( over 3.5vdc on the TP pin can cause UNFLOOD mode and all injections stop, depends on ECU year and its software) "Check . (thus real, and no errors set) If these ck ok there are other more complicated issues you would need a scan tool to ck. See 1989/90 procedures here and quite unique. (on say a Toyota ,we set it to 0 ohms), (I then look down the Throttle air horn and be sure the brass yellow TV valve is 100% closed, if not?, all this is hopeless. These settings adjust how much fuel, at varying . Connect the voltmeter red lead to this pin and place the black lead on a good engine ground. This is caused by worn carbon on the above rings, end of life. . Put back to stock and sold. (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 !! It should be mounted to your throttle body, which is on top of your engine. If the ECU Pin A14 blue-white wire grounds, to the body of the car , the car is DANGEROUS ! 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. In the example below we're using the Zenith Stromberg 175CD carbs but the same idea applies to any of the carbs used. : (the others are for validation steps). So, I took the TPS out of the throttle body, and plugged it into the harness and . Turn ignition switch is "OFF' wait at least 10 seconds. Push the multimeter pin into the TPS screw and check the voltage. Test the voltage of your TBI using a multimeter. Do not over tighten the driver like a nut as there are few threads on the throttle shaft and it can be stripped. I use tinyalligator clipsto comment my DMM meter to the TPS male pins, or I remove old female pins from spare connectors to make up test wiring. they are set loose per the FSM. If the engine doesn't have enough air, the air-to-fuel mixture ratio is off, and some fuel might be left after the spark. An electronics guy, calls this the wiper pin, that is because it wipes the carbon, as it moves and picks off a new resistance, as it moves. '96 ext. At idle, its .54 volts, which i think is correct. as a secondary function to adjust the minimum air setting. (to avoid this nasty EFFECT) TPS part numbers. Locate the throttle position sensor on the throttle body, and unplug the attached electrical connectors from it. ( 2 nuts hold the bracket on, only) The throttle shaft is somewhat flat at that point. The idle switch must be closed and near 0v running or the timing freezeand many things will fail. 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. If your Chevy Equinox has a bad throttle body, it can cause it to run terribly. This test result doesn't condemn the TP sensor as bad just yet. For sure BENCH setting is super easy, and works best do to , you see carbon blockage at TV/ Bore , and fix that. The TPS usually can never causes stalling, the #1 cause of that bad act, is EGR stuck open. Key ON: No start(we will measure, the 4 pins live and hot, anduse back-probing method)All connections, normal, no disconnects! fast. PRO GRADE. So there are 2 tests and only 1 calibration. After replacement of Idle Air Control (IAC) valve, system must be cycled as identified for PCM to properly control idle speed. TPpin is the Throttle angle pin (wiper) of the TPS, not the idle switch. The wires related to TPS, were cut/shorted to the ECU or TCM or Cruise controller, or shorted by theAudio/Alarm installer from HELL! 300 or less is a better goal as most do near 50 ohms pin 1 to pin 2. Below is Throttle body shown up side down, setting the TPS the easy way, its near impossible to set on car, with the above bracket in place. If you also look carefully the TV throttle stop screw isblocked from anyone touching it !!! Select the configuration button. J18 idle speeds out of control are covered here. on the engine (such as what would occur if the automatic transmission was it is must be indexed correctly ! Seechart on top of this page. On a 100% factory stock engine, you should never and kick down cables. see? (the ECU idle serve fights the drivers actions) (idle speed controls) can be more.. 1,287. ON THIS at all ! This mode of running is very rich fueling (and very crude) and the CAT converter will overheat. TEST 1: Checking The Throttle Position Sensor (TPS) Signal. (not indexed to the body correctly, per the FSM) The engine has huge induction air leaks , making the TPS ECU monitor software report false TPS errors. this late discovery causes lean bog and self corrects. TV= throttle valve, that is the butterfly valve, dead center inside theTB,the Throttle body. Sides: The screw is set with very tough loc-tite. (the red numbers below , are odd GM /GEO numbers, I ignore them) All sizes are in inches (imperial USA inches) times 25.4 for mm. The TPS angle pin is watched by the ECU for the driversfast moving right foot. The TPS is the key sensor (instigator) to Enrich mode, that ends STOICH air/fuel/ratio , entering Enrich mode,as seen here. Adjustment is made by rotating the TPS driver slightly clockwise to increase voltage. it must not be stuck at 5volts. more to allow more air to enter the engine. IF the TP pin hasglitches as you accelerate? Michigan. This may be .045-.065 volts. POT wiper pin or throttleanglepin : (Cold circuity test), (POT side is never calibrated , only the switch side is calibrated on any of the 1.6L). ---===<<< 2001 Xtreme X-Cab 4.3 W.I.P.>>>===---. (common on high mileage cars) TB. even when your driving and just cruisin like 30 mph . Be sure to wiggle all connections while watching scan data/voltage readout to make sure the problem is not a loose or bad connection. You control the throttle body position with the . Click to zoom image. The TPS is now calibrated and validated. What you do is: (3 ways to joy? The throttle stop screws primary function is to If all is good, we can skip the calibration. There are three pins in the connector, 5V, Ground, and Sensor. Push the multimeter pin into the TPS screw and check the voltage. Bucking or misfiring (rich) You are done. 50-1000 ohms is typical before the infinity CLIFF. neutral (manual trans). This may be .045-.065 volts. Seeing the ceramic substrate and the carbon thin films , is very visual and clear what is going on inside. THE REAL DEAL ! See Full PDF (8pages) factory CALIBRATION. all years. even a $10 analog Walmart meter will work PERFECT here, no need to buy expensive tools to measure 5v and 300 ohms. This occurs because the ISC idle servo action was not canceled, at throttle tip-in. are you using the stock TPS? operated at normal road speeds (35mph or more). but at with the pedal to the floor, it only goes to 3.9v (the old sensor did this too, probably didnt need replaced.) Push the multimeter pin into the TPS screw and check the voltage. It comes from the factory with a protective metal cap over it. NOTE: On (A/T) models, connector terminals are identified by This method guarantees some tiny fractions of inches ( of over/under-travel.) Photo #2 (early TBI) this is a real photo. Any one of the above issues can cause a an IAC fault code to set in the ECM. If it does not vary in this range or has glitches or has dead spots, it is bad. Lock down those TPS side screws. If your meter is a fixed range meter not auto ranging then ,use the 2000 or 2k ohm range. This is no gold contact switch, its only CARBON! Diagnostic Trouble codes: Idle Air Volume Learning (Throttle Position Learning) What is it, what does it do? Then the ECU causes a hesitation when you demand power. (auto ranged meters, works ok too) Theidle switchwill be below 300 to 500 ohms or near0 voltsidling (lower ohms, is ok , higher not, when at idle) {mine reads 50 ohms } It will never read 0 ohms. (on say a Toyota ,we set it to 0 ohms), The reason 3 gauges (feeler) are used is to compensate forhuman errors setting this switch. Never touch this screw below, the feeler is the Calibration tool . end test 4: Predicates: intake manifold and outside (ambient) air. repeat them all. what do you mean? TheNincompoop section, there areno limits to damageor people doing crazy things to cars, wrong parts, or damaging them. I'll post a pic of it later. plugs. Photo 2: TPS (TBI G16A only) This TPS connector shares the injector connector. The key to success is understanding the threshold issues during calibration. There are many failures on the EFI system that can seem like a bad TPS and is not. internal loads/friction which can also result in a drop of idle vacuum levels. This damage happened during and engine removal. (the ECU cant tell the difference from a glitching TPS or a driver with a wild right foot) The easiest way to adjust the Throttle Position Sensor (TPS) is to use the shareware program WinALDL. Lock down the TPS side screws. Remove the key from the ignition. Eg. If you dont have a scan tool and you are working with a pre 1994 model Gray/ yellow 0 Volts. The FSM instructions, are are linked in every section on calibation and does cover this step. This shows you why the switch part never hits 0 ohms, like a real switch, that is because this one is Carbon, not gold contacts. car is only sputtering on low rpms. Again, percentage and voltage are co-dependant and at WOT the red arrow points to the TPS voltage reading which should read 4.2 or more. To help us guarantee the correct parts for your classic car. Dashpotmust be retractedby hand, during tests, any of 3 ways. FYI: CW = clock wise. To be sure,must guys just set it to .026 drive around the block and all is well. 1991+, Graphic 1: You can do on car voltage tests, or simple ohms (resistance )test. Hold the TPS in place and tighten the retaining screw with the Phillips-head screwdriver. Wrong engine in car, wrong ECU, wrong, THROTTLE BODY, some joker put the wrong generation parts on top of engine? The late to open idle switch, will case Tip-in fuel mixing problems. edicts. neutral (manual trans). and forming a tar like substance.GUNK prevent the throttle blade from closing too far and getting wedged/stuck in the The TPS isinfamousto go intermittent first, then fail hard. (7/16 inches). Once youve downloaded and installed the program, configure it per the directions below. Turn the throttle down by tightening the TBI's screws. Close the hood of the car. ), In all cases, if the TPS is not installed and indexed and preloaded correctly, to the TV end pins per FSM, all bets are off. 92-98 Thedash potdevice must be retracted engine running. The TPS was calibrated using the wrong feeler gauges, as seen on many store, rag books or on line. The 89/90 TBI is a very hard car to adjust, because the Idle adjust screw(stop), changed at ANY time?, wrecks the TPS calibration (Suzuki corrected this pain, in 1991, folly?) This was. (off topic ) The Dash Display TPS reading is almost Zero and the voltage reading has moved into the 0.50 volt range. (all ways) If idle speed is not okay after cycling system, problem is usually caused by a dirty throttle plate or vacuum leaks. If the TPS goes bad it can make the machine run erratically, or cause a hesitation at certain rpm's. G16A. and Fast idle commands(ECU) will never happen. The TPS acts oddly, because the ECU is in. That would put the main line pressure to maximum. Location. Pin B must not be stuck at 0v. The Switch side Low ,will vary from about 20 ohms (50 ohms is par) to 300 ohms closed (experience) and then go to open circuit, very soon ,as you crack the throttle open just slightly. (blocking it open). the observed IAC position counts come to rest within the spec range I If you have a scan tool, I recommend allowing the engine to warm up to The throttle crank (where cable end fit) must land on the throttle stop screw head. Disconnect the TPS main connector , this connector has 2 other pins, for the injector , please ignore the injector pins.(red/yell). so the engine idle speed obtains 550rpm in drive (auto trans) or 650rpm in The idle switch is the only device calibrated here. The IAC works by bypassing the closed throttle plate, the valve allows air to circulate inside the car's combustion area and allows the vehicle to idle smoothly. I think your Throttle Position Sensor is different from mine. Rotate TPS CCW , very gently and get the TPS switch to just close, just barely. (over range, on the meter , means Infinity , and that is what causes, DTC-44 flash code errors, at idle. What is it? adjustments dont (factory set) (the bracket does come off easy) It also sends a signal to the ECU when the throttle is closed, so it can adjust timing and fuel delivery accordingly. This Graphic is just to see where pin 1 is and all 4. this would result in it getting wedged/stuck closed in the throttle bore), some As noted above, when you have the percentage number correct, the voltage number will also be correct. allowing unmetered air to enter the engine, The throttle stop screw The throttle body costs between $200 and $500, while the labor cost is around $50 and $150. November 11, 2019 by Jason. Thats very very helpful! The TPS should read between 4.0 and 5.5 volts. Open ground pin, the TPS goes to 5v and ECU may give warning and engine may not start and DTC code 21 It will never read zero ohms ever, like real gold contact switches would. The Fora platform includes forum software by XenForo. Tighten the screw by turning it clockwise. Setting the throttle stop screw can be (the ECU does not use this way, but I check it so I can find glitches not found , B to D.) at throttle tip-in (evil effects here). 1. There is a Torx screw on the side of the throttle body. The ECU uses this signal to adjust the fuel injectors and ignition timing. Adjust the TPS sensor by reading the ranges of the high and low increases and adjusting the bolt on the top of the sensor until all four readings are in the normal range according to the meter. Loosen the two screws securing the sensor to the throttle body using the Phillips screwdriver. Just give it a try. BATTERY from A to D (plus on A) connected directly then add a resistor from B to D(minus battery side) this simulates a real ECU load. 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. Any time the IAC valve is replaced, this learn procedure should be 1. If not get one of the HAYES or CHILTON manuals manuals and do some reading. TPS not bad ,so test it first (using volts above live or resistance tests). End fast testing. (suck means, use vacuum hand pump tool) or remove theDPwith that single stud screw. Never ground out the +5vcd refr. Keyon, NOT RUNNING test: The 16v TPS has no pig tail connector like 8v has, but has 4 pins, and pin 1 is on the bottom. Yes, the TPI bikes have a screw to adjust the throttle plate idle position but it's not user adjustable in stock form (most likely for emissions reasons). I attached a photo to this post. Use a hand vacuum tool to retract it for calibration. Back probe the TPS connector, using theneedleson the red meter test lead. that is allowed to enter the engine thru a closed throttle. By the way, if idle speed is out of control ?,with the switch closed (0-volts) is coveredfound here. This program lets you connect your laptop to the ECM to conduct data logging sessions while driving the car. (below 300 is TPS spec) {ECU wants below 500 ohms but spec is 300}, If the TPS screw mount slots bottom out, here theTV valve shaft is bentor the valve stop screws were. (put the. This short video covers the instillation and calibration of a new TPS unit. You will see a menu with multiple different settings, and you need to focus on the Accel pumps (20f, 65f, 170f) and Fast Accel (20f, 65f, 170f). Any voltmeter can work here, even a $10 one. Pin 3 TPS TP pin wiper POT or TP throttle angle Gray wire output varies from .5v to about 3.5v idle to WOT. These 3 cables must not be set tight, with dash pot retracted on 8v TBI engine. See very different 1989/90 G16A. Myth 1: No, the TP side does not set fuel injection rates, that is, the ohms (voltage) does not get scaled directly to injection quantity. (a fool proof calibration) All pins names and locations are seen inFigure 1 above. This is the Fast ohms tests, unplugged tests. It can also be used with the cars ignition turned on but the car NOT running to check other data relative to the TPS. It is not the device that determines, fuel rates (flow) at idle, cruise or WOT ! This program lets you connect your laptop to the ECM to conduct data logging sessions while driving the car. Pull the air duct off the throttle body. on the engine (such as what would occur if the automatic transmission was Car won't accelerate, lacks power when accelerating, or accelerates itself. 1.8L DOHC J18 engine (or 2.0L J20) Sport Suzuki TPS calibration on the throttle body. If You cant get zero volts (or near) the throttle is blocked open by something or the TPS calibration is way off, or the TPS is bad, at Calibration proves this out later Connect voltmeter negative lead to terminal "B" (M/T), or terminal "D" (A/T) of sensor connector. NO MPI engine G16B has such a device. (myth debunked)The exceptions. 6932 Views 1 Reply 2 Participants Last post by Matt_vs_YJ, Aug 7, 2008. They utilize a MAP sensor, coolant sensor, knock sensor, and other TBI controls appropriate for the model year of the engine. after 100k miles many TPS can fail on any car, and depends, on utility, be that, city ,highway or mix, when that happens. It also shows you how the carbon works, the Gold wiper device is missing here. The ECU now throws, DTC errors for the TPS. Buy TPS Sensor Sender Throttle Position for Volvo Penta TPI MPI EFI MERCRUISER 805226A1 3855184: Throttle Position . TBI Adapters; Throttle Position Sensor; . (warning the TPS actual wire colors can vary, but not the car harness colors that dont. On my 1996 the top of the TB has this huge black beauty plastic cover blocking all linkage,; remove that first,. With the IAC valve Loosen the top bolt on the TPS sensor a couple turns with the socket wrench. Tips for adding power to a throttle body injected (TBI) Chevy 305, 350, or 454 V-8 engine. Connector unpluggedat theTPS 16v: (it has connector locks, be careful we cant buy new ones) Throttle Position Sensor 1991 Chevy Silverado Throttle Body Idle issues SILVERADO BLUES MEMBER 1991 CHEVROLET SILVERADO V8 2WD AUTOMATIC 89,900 MILES I just completed an installation of a 400 SBC into my 1991 Silverado C3500. DC voltage is measured between pins Sensor (+) and Ground (-). Patton Machine offers a large library of product information and support videos in our Installation Support Center. Ohms. Sorry I didn't have enough time earlier to post up all the details. Icle > IAC Startup > IAC Park Position Using the software - Idle ICF (tachometer icon) > IAC Parked Selection 1. due to fuel cut at cranking time. Attach an Ohm meter (DVM set to ohms resistance starting on the 2k range 2000 ohms) per instructions. Cheers !, you are now calibrated. the TPS is out of adjustment or the sensor has failed. This TBI 8valve device (back side of Throttle body) must be retracted someway to do the TPS calibration. the vacuum level to drop at idle, which will require the IAC or throttle blade Remove it and check it. Those values are perfectly fine for the TPS. I check that C to D is equal to or below 300 ohms throttle closed (if not it needs calibration) (G16A TBIDash potIS FULLY retracted) if infinity its out of calibration, if 300 or below its OK. Tools: We also have OE-level training and advanced diagnostics, including reset adaption, adjust/reset of the throttle actuator and EGR valve coding. 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. TPS installation and adjusting the TPS. (minimum air setting). on pins C to D. or other errors. TBI throttle position sensor chevy small block throttle body injected Efurd Garage 7.12K subscribers Subscribe 35 Share 3.2K views 10 months ago One way to change the throttle. AHof13. Adjust the TPS to 0.5v that is 1/2 volt, exactly. (just harnesses, if lucky). Factory TPS calibration procedure for the 16valve MPI 92-98 Sidekick or Trackers. ), Photo #1:(aka.
