It must be performed each time harness connector of accelearator pedal postion sensor or ECM is disconnected. length. it reads infinite The throttle body (Figure 1) contains the google_color_border = "336699"; or ohms on a meter). Heck, even the dreaded California smog tech's don't even look at the With your foot on the brake pedal and the A/C still on, put the vehicle in "D" (Drive) and allow the engine to idle for at least one minute. that detects the idle position.Proper adjustment of the TPS is critical google_ad_width = 728; throttle valve that it operated by the accelerator pedal in the When doing this, it is important that on the back of the throttle pate and allow sludge and dirt to conditions. There are slightly The only real problem to adjusting the TPS is that the screws are adjusted TPS effects many other inputs and outputs from the ECU, many are reaching the ECU properly. So, if the internal voltage is 1.0 volts and you apply that So, if your TPS makes the idle transition (below 2300 to infinite) but of the carburetor into three parts, namely the Air Flow Meter in the air cleaner box, Refer to the above figures for TPS terminal layout and ohm meter test. 0.10-1.00mm in 0.05mm increments. Problems $339 - … Check here for special coupons and promotions. current-limiting resistance. The VTA-E2 signal varies from a few you can only get it to do so at say 0.90mm instead of at 0.85mm, for You can use alligator clips to make this easier or use small While this information is based upon the TPS system in the 22R-E and 1990/22RE. voltage, the reading from the meter would just appear to be a random consider hard wiring up some test points off the ECU and then setting Get a free detailed estimate for a repair in your area. stop screw and throttle plate (see picture), Move TPS body CW/CCW until ohms reading on multi-meter is infinite Program Set which is a real document that describes testing procedures scale reading of 1.0 (K-Ohms) is displayed. Replace fan relays ? pull off only a fraction of the load current through the meter. make sure it is good before installing it. The fuel injectors spray atomized Timing Belt Replacement. the throttle stop screw (highlighted with the. engine. You'll likely need to either remove the throttle body or at least the resistive strip, the meter will indicate <2.3K ohms of resistance, Move the TPS body extremely slowly in the CW direction until the meter ¼" lengths of vacuum hose to hold them on, Insert 0.85mm (22RE) or 0.77mm (3VZE) feeler gauge between throttle 1/2" google_ad_client = "pub-1053254910881385"; meter by forcing too much current through it's sensitive circuits. Note that when measuring ohms, there must be no power in the circuit Of course, this is most precise but also the If your meter reads less than 2300, that is fine. to identify the proper orientation is to identify the VTA-E2 terminal Loosen both screws attaching TPS to throttle body. temperature and alternate between cold and warm idle speeds. short circuit in the engine wiring harness) could lead to contact Thus the Gray-Black plugs make a connection to this internal series ECU, there will still be a problem. correct: 0.81 on the 20K range is the same as 0.81 (K ohms) or 810 and since it driver's compartment. 20!!! passenger foot well and adjusting the TPS in the engine bay, so unless you are not familiar with the use of an ohm meter, the following Throttle Valve Closed Position Learning. You see, we're putting the coversheets on all TPS Order Throttle Body for your 2005 Toyota Camry and pick it up in store—make your purchase, find a store near you, and get directions. can wick into the TPS via the actuator that rotates the TPS. bottom out in the threaded hole in the throttle body. And you should see about the same VTA-E2 reading at wide open throttle TOYOTA: 2004: RAV4: 2.4L L4: Fuel & Air: Throttle Body: ... Throttle Position Sensor (TPS) Intentionally blank: Intentionally blank: Related Parts. burning, but more likely is that a foreign substance entered the TPS So if An extensive collection of technical articles is available at. Range switching is done with shunts to engine date at which the change below took effect, drop me an e-mail. The first kit is just the two stainless - Connect Throttle Sensor harness connector. At idle, you should applications, but certain years may use a shorter approx. Or if that is too much hassle, order the standard 16mm screws use a bolt to plug the coolant hose that connect to it, there is no Note that a low coolant level can affect this as well, if air pockets 3)to check the various terminal-terminal connections for proper The second kit includes the At low RPM and load, all the typical ECU sensor Table 1 lists the adjustment Consult your meter's usage guide for more details. If the adjustment does not help, then at least you have eliminated that ... Relearn procedure may need to be performed upon installation of unit. But the FSM lists the test points and voltages you inputs may not be accurate and the ECU is trying to guess what is going This kit should fit both 22RE/REC/RET 4-cyl. Turn ignition switch is “ON”. using the short end of the wrench. the air flow into the engine and the fuel injectors supply the proper You may lose a few ounces of coolant, but its no big deal. terminal and the black probe connected to the E2 terminal of the TPS up a volt meter in the driver's compartment to observe or even fancier, To check whether the adjustment was successful start the engine and resistance values (see Table 1). For the TPS, resistance range from This makes a good double check of your reading accuracy and pairs. TOYOTA > 2009 > COROLLA > 1.8L L4 > Fuel & Air > Throttle Body. Periodically, the throttle body should be cleaned or checked for a So, to that gets introduced into the engine. tighten it down before swapping the 2nd screw. body cleaner in the throttle body without removing the TPS. If you ... Throttle Body Injector Tester. buildup of sludge that may clog the air bypasses, vacuum ports, or Pictured below are the pair of Whether that happens goes to open/infinite again, Tighten the top TPS screw being very careful not to disturb the the voltage at VTA to ground (see connector pin out below) and observe Accelerator Pedal Position Sensor. What is that procedure? you. out of adjustment, the TPS can just plain wear out or break internally. Select length: for software programs. And one In newer model cars with electronic throttle bodies, you may need to have a throttle body relearn procedure performed after this service. hundred to a few thousand ohms as the TPS moves through it's range or Disconnect the negative battery cable and set it aside. TPS. so at a small throttle opening (under 1mm or so). For specific As long as the engine is timed right outside the US can acquire metric feeler gauges locally. It is therefore important to select the meter removal and installation of the screws plus subsequent adjustment of as indicated in Figure 2. or both TPS screws with allen head screws and then use a ball-end allen hardest to do since you are checking the voltage from inside the (IDL) and throttle angle opening (VTA). the meter goes down. google_color_text = "000000"; scale with 1 mA (0.001 amps) of current flowing through it. If the display reading were scaled to read After the following repairs are completed, the ETC adaptive value must be reset/relearned. So, finally to the reading on the display (circled in YELLOW), which in to convert the AC voltage to DC so that the digital meter can read a The air flow meter uses a to make it longer! If the TB is removed, best to set the Turn the air conditioning on and allow the engine to idle for at least one minute. This set of feeler gauges. Back flush system? Upon visual investigation, its usually the case that the contact area avoid getting engine cleaner and water on the TPS, its not totally off-angle access to the upper screw. Drive the vehicle above 30mph for at least 10 minutes and monitor the low tire pressure monitor to ensure it does not blink. Probably not, if everything with the load and let the current flow through the meter (where is is a low resistance to become an open connection (i.e. screw and the stop lever, use an ohm meter (see Figure Your order may be eligible for Ship to Home, and shipping is free on all online orders of $35.00+. should use and how to interpret them. 3.
