A $250+ Suzuki part. Ground the black multimeter test lead on the battery negative (-) terminal. Patton Machine offers a large library of product information and support videos in our Installation Support Center. Setting the throttle stop screw can be (put the. they are set loose per the FSM. Verified Purchase. Be sure to wiggle all connections while watching scan data/voltage readout to make sure the problem is not a loose or bad connection. loosen the TPS screws until just a tad loose. Insert a safety pin into the 3G connector on the voltmeter, sliding it between the rubber seal and the electric wire. You need to back off the driver set screw 1/2 of a turn to set them properly. TPS is connected to its harness. Other pins open will throw over voltage DTCs for TPS. My broken TPS, internals,hackedopen. at throttle tip-in (evil effects here). Side one is called the IDLE SWITCH , the other side, is the TP (throttle position side or Throttle Angle), This side form a basic Potentiometer, (POT) or variable resistor. Closed means less than 300 ohms. (due to flooding) (it the ECU, mimics the bad TPS and runs VERY BADLY). All pins on allMPI TPS look like this and rules and wire colors ! (all makers of this part, have rip off prices, its no Toyota, so they can do that) Stick the pin in the center wire of the throttle position sensor plug. If the idle switch fails, the ECU will not allow idle speed controls. (+5 vdcis applied to the TPS pot pin A, from ECU, if not , ECU is bad or this pin A wire is grounded out.. or cut) 4.75 to 5.25vdc is factory spec.. Plug the cable leads into the TPS sensor. Any ohm meter works, here, even the $10 Walmart meter, works very well. Select the Dash button which will open the Dash Display (Yellow Arrow). Photo 2: TPS (TBI G16A only) This TPS connector shares the injector connector. Rotate the sensor left or right until the voltmeter displays 0.50 volts. if any of these steps fail. If your Ford Ranger has a bad throttle body, it can cause it to run terribly. This switch is not a gold contact switch, its just a carbon chunk, It has only 2 readings. Thats very very helpful! 1) Connect volt meter just like above atsetup1. (7/16 inches). Seeing the ceramic substrate and the carbon thin films , is very visual and clear what is going on inside. This is very common , this failure of the TPS. Code 44s, and timing freeze fails to work (the jumper). First of the throttle angle pin is not calibrated (the ECU auto calibrates that in software) and is a crude device. The TPS can crack inside (see photo just above) or wear out inside and give totally random symptoms. See chart above (table) for exact Go , NOGO and CAL feeler gauges. (it is just a vacuum servo motor, a vacuum actuator Attach the negative (black) wire of a voltmeter to the vehicle's frame to ground the device. The PCM on that truck will look for a TPS input signal to help determine the shift points and main line pressure of the 4L60E. (example of throttle angle testing and finding dead spots or glitches) AT4X versions of the GMC Sierra and Canyon. Very bad that. Get. (aka SPI ,er, single point injected, bla bla) Tepco Cycle Repair 16.1K subscribers Subscribe 166K views 3 years ago Sweet tool by TPStool.com to make adjusting the TPS quick and easy. This mode of running is very rich fueling (and very crude) and the CAT converter will overheat. This fuel then makes its way through the system and could . (minimum air setting). Adjustment is not possible. Side1 is the calibration pin. on the throttle blade or throttle body bore, The throttle stop screw a tad, so the TPS can move easy, and rotate. problem with the engine resulting in lower than expected vacuum levels at idle Turn the stop screw back in until it just touches the linkage, then turn in turn more. Turn the key ON but don't crank or start the engine. If all is good, we can skip the calibration. All tests are done keys in pocket. Plug the cable leads into the TPS sensor. To check that the TPS is getting power, go to: TEST 2: Verifying Throttle Position Sensor Has Power. on TPS look here. Leaky throttle body base gasket.Very comon on this engine.I don't know if you serviced this when you pulled the intake. Larger displacement engines require more air to Do not over tighten the driver like a nut as there are few threads on the throttle shaft and it can be stripped. Throttle Position Sensor Diagnostic Manual $2.99 USD All of the information you need to diagnose the throttle position sensor problem or trouble code. This table was made from real USA FSM data. Pin 2 must be below 500ohms key off connector off. throttle body is being used than what originally came with the engine. Factory TPS calibration procedure for the 16valve MPI 92-98 Sidekick or Trackers. The IAC valve cannot be tested using conventional You've adjusted the Throttle Plates using the idle stop. (A/C fast idle), If not closed this idle switch, at idle the, if set (closed switch) to far into the TPS range, then the car , will have TIP-IN bogging. The reading should be the same as the previous reading. Never touch this screw below, the feeler is the Calibration tool . Loosen the two screws securing the sensor to the throttle body using the Phillips screwdriver. loosened the mounting screws unintentionally -- it happens) then minimum air should be adjusted. The throttle stop screws primary function is to (Infinity) Adjustment is made by rotating the TPS driver slightly clockwise to increase voltage. It tells the ECU how far open the butterfly in the throttle body is. 5) FYI: Myths: MPI is 16v Multipoint Injection motors, and has no Dash pot steps, or device. Make sure the throttlefully drops the butterfly and end crank against the stops,there is a screw there, that bottoms out, do not ever touch that screw. Un-flood mode. Adjust the idle stop screw Loosen the throttle position sensor retaining screw with a Phillips-head screwdriver. but at with the pedal to the floor, it only goes to 3.9v (the old sensor did this too, probably didnt need replaced.) This TPS was stuck in UNFLOOD mode, car will never start. There are many failures on the EFI system that can seem like a bad TPS and is not. The TV must not bepacked in GUNK causing TV to not fully close. The TPS switch is not closed at idle, for any reasons. (gotsymptoms?) to be opened up to compensate. (auto ranged meters, works ok too) Sides: CASE 3: The multimeter DID NOT register any voltage. (your meter manual shows these facts) (89-95 years) Eg. pin on the TPS, or you MAYblow upthe 8v ECU copper circuit trace, 16v is better protected. The throttle position sensor (TPS) is a device on the engine that detects the position of the throttle plate. AHof13. stop screw on the throttle body. less than 500 ohm and infinity. (takes human testing to find this flaw, the ECU is very dumb here), Warning,(TPS calibrated to open late) Your Ranger's throttle body controls the amount of air that enters the engine. Easy to install to replace 20 year old components. Only the Dashpot on top left of TB throttle body, is allowed to do this. Now press the accelerator pedal all the way to the floor and hold it there until the Dash Display stabilizes with the Wide Open Throttle (WOT) percentage reading. Adjust the TBI. Figure1 What Does a Throttle Position Sensor Do? TPS Throttle Position Sensor Extension Cable Fits Camaro Firebird Corvette TPI. Michigan. Pre-conditionals: There is little to no adjustment on the TPS assembly, 2. THE REAL DEAL ! NOT start the engine. One example of this is when the engine is modified, or a different Secure the bolt at the bottom of the TPS sensor and attach the hoses to the sensor and inlet pipe. The ECU checks for errors (DTC) on the Angle side., or wires cut to it (cut means , really cut broken or any connector in this path RUSTY) (rusty , corroded, broken pins, bent pins, smashed ,etc) now just put the throttle body back on while being care full not to bump the TPS, put . Also, the IDLE switch part is not a real gold zero ohm switch , it too is carbon, reading about300 or 500 ohms. Turn your car off by turning the key counterclockwise. Seen moreclearly here. Unflood mode forever. This page covers calibration or testing the TPS. (0 volts connected on a running engine at idle (hot)) To help us guarantee the correct parts for your classic car. DTCs? to discuss your individual requirements, final costs and delivery interval. THE OHMS test. Omg what is a Carb? It is nota precision voltage or ohmic reading. Note now that the main resistor A to D is very crude, its not precision at all, so if yours reds 4000 ohms and steady , then that is what it is. Seeing this aberrant glitch with some DMM can be very hard, as they are so slow to measure, and can miss the glitch. I am hoping to get some advice about an issue I had with my Cruze earlier today. Pin 4 +5vdc from ECU. Change along with o2 sensor . Follow normal service procedures to remove the TBI assembly from the intake manifold. (8v example) or hackers messed up my car? BEGIN TESTING the G16A, TBI engine 1991- 1995: (8 valve , engine only) The 3 video tests (mp4) PHOTO 3: 92-98 look same. When they do, they usually freeze up or get stuck in a fixed position. You may see a Com Port error message. TPS idle switch Calibration G16s , J18/J20 engines. So there are 2 tests and only 1 calibration. are you using the stock TPS? It will never read 0 ohms. This allows the installer to simply and easily mount the TPS sensor and adjust it so it delivers precise throttle position information to the transmission controller. Unscrew the TBI's bolt with the wrench and pull the TBI from the car. The TPS was not set with the feeler gauge on the threshold of closure. The TBI engine G16Adash pot devicemust be retracted first ! This page covers calibration and testing , on car or off, volts and ohm methods. Keep in mind, when you set the.016setting (example) you then remove the feeler , and the throttle retracts .016 and you get a solid repeatable less than 300 ohms each time. Locate the TPS on the throttle body near the air intake hose. cab 4.3l 5spd 2wd, '07 4.3l out of GMC sierra, centerforce stage II clutch, HURST Sport Truck Shifter, Richmond Powertrax, 3.73, underdrive pulleys, gutted airbox, & one bad azz driver! Resetting the throttle body on a Honda is very simple. Preliminary setup: (have the 3 feeler gages in hand, or stack them, only 1 feeler is needed to do just the CAL. You need to back off the setscrew in the driver 1/2 of a turn to set the voltage properly. To start with, turn the key to the on position and then find Go EFI Tuning on the main menu and press enter. M/T = Manual transmission, A/T , yes, automatic (this is all ASE /SAE jargon. Throttle Valve Closed Position Learning. (despite vast myths) NOGO= Open Switch. Tighten mounting bolts. 1985-1992 Firebird 305 and 350 TPI. The throttle position sensor (TPS) circuits (wires) that we're gonna' be testing are: Throttle position sensor (TPS) circuit A: GRY (gray) wire and it connects to the F-14 terminal of the blue PCM connector. The next steps are an audit of your work. 1. The engine is.030 over with a EFI cam and 9.5:1 compression with aluminum 63cc heads. it needs calibration or error 1 ,2,3 corrected above) If the ECU is infailsafe modedue to a Dead MAF (MPI) or Dead (MAP)sensor, the ECU then uses the TPS tomimic this dead sensor, and now becomes the only (+ RPM) way to measure air flow. This occurs because the ISC idle servo action was not canceled, at throttle tip-in. a $2 tool. Test 2: Pin D, the ground pin test, it must read 0 volts , zero volts 0 to 0.5v. (using just a cheap SMOKE detector battery) Angleis never calibrated. 1. You will need a couple of paper clips or pieces of thin solid wire to reach into the back of the TPS connector when its plugged into the harness. FYI: CW = clock wise. No dash pot. The readings should be the same as seen above in the WinALDL testing method. Never adjust the painted or capped off,throttle stop screw, for any reason. The two numbers are dependent on each other so if you fix one, youve also fixed the other one. operated at normal road speeds (35mph or more). This program lets you connect your laptop to the ECM to conduct data logging sessions while driving the car. the vacuum level to drop at idle, which will require the IAC or throttle blade These 3 cables must not be set tight, with dash pot retracted on 8v TBI engine. (the reading of 4.0K is 4000 ohms.) SFYAUTO CPS Crankshaft Position Sensor 12596851 5S1695 Compatible With GMC Pickup Chevy Silverado Suburban C1500 K1500 K2500 K3500 G30 P30 Cadillac . That means it can't calculate the fuel and air ratio. (if the auto ranger shows 2.01 K that means near 2000 ohms, K means times 1000. Ensure all vacuum components are functioning properly. The TPS is the key sensor (instigator) to Enrich mode, that ends STOICH air/fuel/ratio , entering Enrich mode,as seen here. Consult the engine diagram that came with your vehicle for extra guidance. The primary purpose a throttle position sensor (TPS) is to give information to the car's computer about the throttle. The late to open idle switch, will case Tip-in fuel mixing problems. use tie wraps or bailing wire to tie it back some way. The TP usually has 4vdc output at 100% throttle. Infinity resistance ohm, is open = ( meterDMMdisplaying O.R, over range, or O.L, over load,see your metersoperational manual, some show over range in different ways) fast. You may cause the throttle to stick open. on the left. Unique changes to J18 engine (evolution) are seen here. Graphic #2 This is not calibration yet, this is just checking throttle angle. TheAnglepin is used for fast throttle enrichment detection and to detect cut throttle. TB. Push the multimeter pin into the TPS screw and check the voltage. This method is used mostly by the hardcore technician. The TP pin pin can do that (DTC #22) and is a bad TPS. If not, remove it using a sharp pointed tool. Put back to stock and sold. WARNING: THEDASHPOTDEVICE MUST BERETRACTED for all TBI, on car checks below(TBI is 8valve engine) (ECU sees, idle switch closed and RPM is a 4000 RPM, and low plenum vacuum..oops.?). The switch side is a bit strange, let me explain. connected, ground the diagnostic (ALDL) terminal (same as you would do to flash Measure the resistance between the TPS connector terminals "A" and "C" with a multimeter. (after the key has been off for at least 10 seconds). (called a load) Engine idle controls dead, the RPM dont hold at. ON THIS at all ! Loosen the 2- bolts that hold the TPS. and kick down cables. This is only one test out of the series of tests you carry out on the throttle position sensor and we . Make sure that accelerator pedal is fully released: 2. See 1989/90 procedures here and quite unique. If you also look carefully the TV throttle stop screw isblocked from anyone touching it !!! Zero=zero opens the throttle vane 1.92 degrees when the lefthand stop screw is adjusted from 10 mV to 250 mV, however, the Motronic only reads 0.32 or 0.64 degrees. 2.Misadjusted or bent throttle linkage.You don't know what was done before you got to it. One is a cold engine. I then drop the DASH pot, arm and the throttle opens and the PIN C goes to near 5 volts, (closed switch ) (however an analog meter may see them or a graphic GMM may, and all scope for sure can). Move the safety pin and positive wire to the 3F connector and repeat the process, checking the increase in voltage. The ECU goes rich, from STOICH mode, and lasts only long enough for the MAP or MAF sensors to catch up. Threshold is setting it, just so the switch has just closed. (I will use harness side colors, because they do not change) This test is long, but is better than guessing and paying $250 for a new sensor !! Test 1: Pin A, power pin test. If not unplug it and check it with the TB closed. Failure of Idle switch: If you have a need for a kit to be custom built to order, please reach out to us to discuss your individual requirements, final costs and delivery interval. Push the multimeter pin into the TPS screw and check the voltage. But there are times when the adjustment of this screw is necessary. 6. Then rotate the TPS CCW, then rotate CW it until the TPS (pin1 and 2 )just barely(at the threshold) go toInfinityon, Remove Feeler gage, note the Ohm meter (Resistance meter) shows continuity (less than 300ohms) (ECU expects less than 500 ) (do not expect zero ohms! This is the reason why GM installs a tamper-proof plug over the throttle The TPS acts oddly, because the ECU is in. The original tps costs too much. 50-1000 ohms is typical before the infinity CLIFF. Use a hand vacuum tool to retract it for calibration. ( except some 1.3L Carb. the 2 (not shown) wipers short the inner and outer rings as they wipe. (but can if the ISC goes dead and other failures, prevent air flow to the engine or very weak fueling as this idle switch will shut down, the ISC) spec is. TPS not bad ,so test it first (using volts above live or resistance tests). The Howell TBI unit was installed by the PO. Lock down the TPS side screws. We do the 4 TPS tests below first, before Calibrationsteps hereto be sure its even working at all. Gray/red To be sure,must guys just set it to .026 drive around the block and all is well. Throttle position sensor (TPS) circuit B: DK BLU (dark blue) wire and it connects to the A-15 terminal of the red PCM connector. Throttle body INJECTED with just 1 injector. (or to the engines shinny metal) For a ground reference. Vehicles Motors Vehicles use the Vehicles in the same manner as most automobiles. keep your foot off of the pedal You want the TPS reading in both the Dash & Sensor Display to be as close to zero as possible (-0.3 in this example). If POT TP wiper pin B or 3(16v) (reads above +3.75vdc ,when trying to start the car, the car will NEVER start. (we cant burn air), ergo the TPS angle pot was invented. Throttle Position Sensor adjusting the easy way! replacing the IAC valve, you should check all of these possible issues first. There are many features and function in the ECU that trigger off this TPS switch, most or all will malfunction. A Missing Dashpot on G16a engine. If the TPS goes bad it can make the machine run erratically, or cause a hesitation at certain rpm's. (all ways) (about 300k) The TPS was calibrated using the wrong feeler gauges, as seen on many store, rag books or on line. (or cause bore wear) Suzuki has NO SPEC. < with good skills you can set it with one feeler(calib). The idle switch must be closed and near 0v running or the timing freezeand many things will fail. They utilize a MAP sensor, coolant sensor, knock sensor, and other TBI controls appropriate for the model year of the engine. special tools available that are designed to test GM IAC valves, but I have If it fails on TB and is good off body, , TPS was mounted WRONG ! plug It is located on the left front corner of the TBI body, just ahead of the throttle arm. Photo 6: The idle stop screw must never be turned. This works on all TPS sensors, only the pin names vary. First, put in Your key and set the ignition to RUN for 3 seconds. This is a simple, stainless steel conversion kit which mounts the very popular GM three-pin Weatherpak TPS sensor directly on the side of the carburetor with an adjustable linkage. The TPS can be tested on a bench too. Part 1 of 2: Removing the throttle position sensor. Connector pin out. The ISC will be dead ! (nor pray tell short this to 12vdc. Install the air cleaner duct and tighten with the Phillips screwdriver. The 89/90 applies but the stop screw has special rules and steps for calibration and idle speeds. The 16v TPS has no pig tail connector like 8v has, but has 4 pins, and pin 1 is on the bottom. More 5.2L, 5.9L Dodge Ram Diagnostic Tutorials. If you get a Check Engine light error indicating that a TPS failure, it is most likely caused by not having the TPS driver nut in the correct position. means potentiometer or variable resistor. When you purchase through links on our site, we may earn an affiliate commission, which supports our community. Pin B must not be stuck at 0v. PO= Previous owners, (mostly with no books or tools) or potentiometer, or variable resistor. A bad idle switch makes calibration , impossible. The Throttle angle pot is acrude5,000 ohm(3500- 6500 ohms) Pot. Removing Your Sensor Follow these steps to replacing your sensor. Neverhot wireanyECU output pins, or you will damage these simple ECUs . DOA: Show and tell: (when things go wrong, never hit your TPS, oops , damaged , I bought a spare like this.! ) The TPS is indexed correctly , that is, inside below the TPS are index pins they must be aligned, and for sure not jamming the throttle open. (cruise , throttle and a/t kick down cables) They then have an idle speed air bleed that is end user adjustable. The reading should be the same as the previous reading. The ECU watches for legitimate fast throttle angle changes, and when it sees them it BELIEVES them (A.Turing brain,mind set) and that they are DRIVER CAUSED. This is what needs to be turned to adjust minimum air, or more commonly known as "idle speed". We must first discount, some the nincompoops reasons to messup (or bad luck) the TV or TPS indexing: See JARGON here Suzuki calls this the TP pin, but is known today at Throttle Angle. back probing pro needles , banana cables to needles. If your Chevy Equinox has a bad throttle body, it can cause it to run terribly. The Suzuki named TP pin is called throttle angle today. BENCH Glitch TESTS? These 2 years, are very unique. If the TPS reads outside of this range, the sensor must be adjusted. (will cause , engine that loves to flood ,cranked cold) but does make calibration easy, sure (1/2 joking). C and D Pins. It is a passive device, no electronics inside, only carbon . disconnect the IAC electrical connector. amount of vacuum an engine can generate at idle. close all of the way, There is carbon buildup The Throttle Position Sensor, or TPS testing (theory). 6932 Views 1 Reply 2 Participants Last post by Matt_vs_YJ, Aug 7, 2008. Hit the Exit button on the configuration box. If you dont have a scan tool and you are working with a pre 1994 model CUTFUEL cranking. Set the scan tool to TPS voltage (or connect DVM) then set the adjustment screw for the lowest value & still touching the throttle arm stop. Turn the TPS center shaft and see that the voltages are linear and that they never glitch. Adjust rear TBI throttle stop screw to approx 6" of H2O on manometer. TPS WIRES This other devices must not short out the throttle angle pin, ever. The dash pot device on the TBI 8v must be. The on car live, key on,voltage testis here. Remove the TBI using an Allen wrench. (hesitations). 1991+, Graphic 1: You can do on car voltage tests, or simple ohms (resistance )test. The voltage will rise to at least 4v (5.2v max) as you advance the throttle, it must be smooth and linear, with no glitching. Theidle switchwill be below 300 to 500 ohms or near0 voltsidling (lower ohms, is ok , higher not, when at idle) {mine reads 50 ohms } I have seen new switches vary from 50 to 1000ohms (in the first .030 of travel.. the goes to infinity (and open circuit) Do not over tighten the driver like a nut as there are few threads on the throttle shaft and it can be stripped.
