Setting the throttle stop screw can be To start with, turn the key to the on position and then find Go EFI Tuning on the main menu and press enter. 5.0 out of 5 stars Perfect Fit for Mercruiser MEFI3 TBI 5.7L Mercruiser. (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. (if this pin fails?, hard, the ECU may go toFailsafe mode, Sets DTC for TPS , if it glitchesNo voltageJumpinessordrop outsallowed! This test result doesn't condemn the TP sensor as bad just yet. For Over 100 Years . In most cases 50 ohms to 1000 is the range on the switch carbon (real hardware) then jumps to INFINITY about .030_ travel off the stops, The only reason this is hard, is the silly carbon cheap Suzuki switch. That would put the main line pressure to maximum. It also shows you how the carbon works, the Gold wiper device is missing here. (Fuel pressure wrong, timing belt slipped, EGR stuck open, leaking injectors,clogged injectors (full or partial)), Exceptions:(to how the TPS is used) The Suzuki named TP pin is called throttle angle today. Now, if there's a problem, there's only two possibilities: [*] There. TPS= Throttle Position sensor, or TP and Throttle Position , on newer cars 96+ it is called a Throttle angle sensor. How do you adjust the volts for the tps? AT4X versions of the GMC Sierra and Canyon. To be quite honest, you dont really see many IAC valves fail. When you first open WinALDL, this screen will appear. Not properly indexing the TV shaft pins to the TPS can cause TPS to stick throttle open. I have no attachment to the c. 50-1000 ohms is typical before the infinity CLIFF. if any of these steps fail. can cause a code to set. Allow the engine to fully warm up and go into closed loop. (if the auto ranger shows 2.01 K that means near 2000 ohms, K means times 1000. ), Photo #1:(aka. and forming a tar like substance.GUNK TPpin is the Throttle angle pin (wiper) of the TPS, not the idle switch. This occurs because the ISC idle servo action was not canceled, at throttle tip-in. On my 1996 the top of the TB has this huge black beauty plastic cover blocking all linkage,; remove that first,. The 4l60e will not respond to manual shifting like the old non electronic . MPI92 -98 1.6L only USA. The TP does get watched by the ECU, for rate of TV action, you move the throttle fast and the ECU sees that and goes toENRICHmode, until the MAF/MAP catches up. electrical testing means. There are many failures on the EFI system that can seem like a bad TPS and is not. Select the Dash button which will open the Dash Display (Yellow Arrow). (to avoid this nasty EFFECT) You've adjusted the Throttle Plates using the idle stop. The Fora platform includes forum software by XenForo. Your Equinox's throttle body controls the amount of air that enters the engine. There is little to no adjustment on the TPS assembly, 2. ( not 300 or 50 ohms or less,or some other value , but trueinfinity). For a better experience, please enable JavaScript in your browser before proceeding. I have seen new switches vary from 50 to 1000ohms (in the first .030 of travel.. the goes to infinity (and open circuit) Disconnect the negative battery cable and set it aside. Engines that have higher compression or are new/rebuilt can have higher shifted into gear). 1. now just put the throttle body back on while being care full not to bump the TPS, put . NOTE 1Exceptions: G16a TBI EFI 1989/90 ONLY using these special steps only. This is the Fast ohms tests, unplugged tests. provided earlier. ( I will cover 92-98 1.6L 16valve MPI method here) A GO /NOGO method this is called. METER MADNESS: *(8 inches HG vacuum dose it) at nipple seen below. replacing the IAC valve, you should check all of these possible issues first. a switch (right) and the POT. and CAL means you get the switch to just close, and you stop turning the TPS body. Be sure to wiggle all connections while watching scan data/voltage readout to make sure the problem is not a loose or bad connection. (ECU sees, idle switch closed and RPM is a 4000 RPM, and low plenum vacuum..oops.?). Turn ON the ignition, but do Hopeless:(and solutions) applies to all 1991 to 1998 G16s. (use the 8v rules for these test above) A $250+ Suzuki part. due to fuel cut at cranking time. These simple tests follow below: TheDash Pot must be retracted, when stated. TPS = Throttle Position Sensor: The TPS is located on the passenger side of the throttle body. DTC errors, 31, 32 ,33 or 34, or starting in 1996 DTC errors P0101, 102,or 103 (These errors trip failsafe), DIY: crude way, ( super easy, super cheap , fast? Rotate TPS body CW , see meter go to infinity. Throttle body INJECTED with just 1 injector. 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). Yes, setting up 94 thou , is a pain, no feeler gage set has this size. Then select the Sensor Data button which will also show the TPS Throttle Percent position (yellow block/red arrow). If all is good, we can skip the calibration. NO MPI engine G16B has such a device. Pin B (TP) (see FSM here)( the normal voltage idling is0.6 to 1.5v) This fact also explains why the GLITCH, if any, also causes the glitch to drop to zero volts. One example of this is when the engine is modified, or a different I do not have a ton a high quality tools. The Below internals of my TPS, are cracked, car will never idle. More 5.2L, 5.9L Dodge Ram Diagnostic Tutorials. Now I cant get a reading over 1.20 volts at WOT. 1,287. See hopeless. (my short list, lol) 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. If the switch fails , the car will NEVER idle correctly ( it will vary with load on the engine) The reading should be the same as the previous reading. The throttle position sensor (or TPS) monitors the throttle body butterfly valve. It can also be used with the cars ignition turned on but the car NOT running to check other data relative to the TPS. (hesitations). I've got an '89 and used a scanner to find out my TPS was shot. When they do, they usually freeze up or get stuck in a fixed position. (my comments are on a normal hot running engine). Previous owner removed it and put it back and now its not calibrated or did the calibration guessing or with wrong feeler gauges? The ECU will not set a code for Glitches. Plug in the scan tool to the ECM. (except 89/90 years) Connect a battery of any kind, to from pin A do D. (pin A is plus pin) (using any cheap 9v smoke detector battery works) have no SWITCH at all now, one just sets the volts and you are done) {0.5v at HOT idle , key on), (Which pin is TP ?. Or bad luck, fate, or ? if yes, its. With your laptop connected to the ECM Data Plug, open the WinALDL program and turn the car ignition to the on position but DO NOT START THE CAR. TPS is located on the other side of the throttle shaft. If the TPS errors are bad enough (with DTCs to match) and constant, the ECU may go, tolimphomemode and car does start. If the cap is still there, use a small punch to knock it out. These 3 cables must not be set tight, with dash pot retracted on 8v TBI engine. Leaky throttle body base gasket.Very comon on this engine.I don't know if you serviced this when you pulled the intake. And very accurate, even i dont know english very well. This page covers calibration or testing the TPS. Attach the positive (red) wire of the voltmeter to the safety pin and turn on the ignition switch without cranking the engine. If the idle switch fails, the ECU will not allow idle speed controls. Herko Throttle Position Sensor TPS6069 for Geo Pontiac Suzuki Chevrolet 94-00 (Fits: Geo Metro) $14.10 Free shipping 95-00 GEO TBI THROTTLE BODY INJECTION METRO SUZUKI SWIFT 1.0 1.3 OE 96 97 98 99 (Fits: Geo Metro) $349.99 Free shipping 200-1143 Walker Products Throttle Position Sensor New for Chevy Geo Metro Prizm (Fits: Geo Metro) $123.47 What matters are the steps. Basics Of The Throttle Position Sensor (TPS). Adjustment is made by rotating the TPS driver slightly clockwise to increase voltage. (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. There are 2 sections in this device, the top section is thePotentiometer (POT) or as some call it a variable resistor. The TPS idle switch must close every time you drop the throttle (to near 0v) Never adjust the painted or capped off,throttle stop screw, for any reason. 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) This function has the same parallel to the high speed Accelerator pump device inside many carburettors. Remove the AWS hose from the inlet pipe to access the TPS sensor on the firewall. The TBI engine G16Adash pot devicemust be retracted first ! (ground) Best place for asking questions is FixKick forum. One is a cold engine. The original tps costs too much. 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. ---===<<< 2001 Xtreme X-Cab 4.3 W.I.P.>>>===---. The throttle stop screws primary function is to I had to stack some feelers to get this. The ISC will be dead ! It may feel as though the car simply doesn't accelerate as it should, and jerks or hesitates as it picks up speed. Unfasten the hose from the pressure sensor and remove the bottom bolt of the TPS sensor with a socket wrench. Even better is a scope on pin, B , testing both forglitches, as you advance the throttle, a TPS when worn, loves to GLITCH ! (for sure ,300 to 500 range works ) (Throttle Position Sensor, Switch) See above graphic 1, for pin assignments. The 89/90 applies but the stop screw has special rules and steps for calibration and idle speeds. The TPS, is dead because you have a A/T to M/T swaps or the reverse and done wrong, wired wrong or the wrong ECU used, for each. ON THIS at all ! Remove it and check it. TPS WIRES This other devices must not short out the throttle angle pin, ever. ), Using Walmart leather sewing needles work great. see? The TPS angles are not calibrated. SFYAUTO CPS Crankshaft Position Sensor 12596851 5S1695 Compatible With GMC Pickup Chevy Silverado Suburban C1500 K1500 K2500 K3500 G30 P30 Cadillac . (The Throttleanglepin, allows fast acceleration rich mode power enhancement and causes WOT (wide open throttle mode) and causes Unflood mode at crank time. trouble codes thru the check engine light). Ground the black multimeter test lead on the battery negative (-) terminal. If may steps below are not clear enough then the Actual real SUZUKI FSM is here. means potentiometer or variable resistor. side called by Suzuki TP pin, is theThrottle anglepin, and allows for the ECU to enrich fuel with a fast right foot. HowTO Replace Your Throttle Position Sensor 1. So before Side1 is the calibration pin. even when your driving and just cruisin like 30 mph . TPS not bad ,so test it first (using volts above live or resistance tests). the observed IAC position counts come to rest within the spec range I The on car live, key on,voltage testis here. Preliminary setup: (have the 3 feeler gages in hand, or stack them, only 1 feeler is needed to do just the CAL. are you using the stock TPS? Adjust the TBI. (non 89-91) FSM TBI actual pages on calibration. it needs calibration or error 1 ,2,3 corrected above) Test the voltage of your TBI using a multimeter. The pin 3 throttle angle varies from about 1v to 4v (non critical) but must be linear in action (foot throttle) and not glitch. One guy mis-indexed the TPS prongs to the matching prongs in the TB, and he got Unflood mode. All Rights Reserved. so the engine idle speed obtains 550rpm in drive (auto trans) or 650rpm in If the meter does not read 5 volts, the TPS is bad. The 8V factory TPS data pages: This page covers calibration and testing , on car or off, volts and ohm methods. Photo 6: The idle stop screw must never be turned. I'll post a pic of it later. You may see a Com Port error message. (22 is stuck low) But there are times when the adjustment of this screw is necessary. diagnostic (ALDL) connector and start the engine. The Throttle must not prevent the TPS from closing, and vis versa. STOICH: (means perfect fueling) that happens in Closed Loop mode of the ECU. In this case well be taking voltage readings directly from the connector at the TPS using a Digital Voltage Meter. Such as Subaru or Grand Vitara? The TPS Angle checks, prevents this hesitation; that is it prime jobEnrich mode. Say the 1991 car has a 1989 actual engine, (or parts) and not 1991 . Put back the Dash pot, as you found it. (<< > > > > > > === --.... Rest within the spec range I the on car live, key on, voltage testis here bad TPS is!
