If you need a Toyota Camry throttle position sensor adjustment then this is the post for you.

Usually the throttle position sensor is present in your vehicle to help track or observe the vehicles throttle valve position in the car inner combustion engine. If the throttle position sensor adjustment is needed when the sensor is not reading and displaying accurately.

This post I will like to show you how to adjust throttle position sensor Toyota Camry though this step can also be applied for other Toyota vehicles like corolla and others.

    Concerning the throttle position sensor adjustment, most throttle position sensor are adjusted at throttle close. In normal circumstances, if the other adjustments are perfect, and your sensor is good and fully functional, getting this adjustment correct will get the job done.

    Note that setting switch-type sensors will need the usage of an ohmmeter. However, on some European car models, a loud click from the sensor should be heard when the throttle is exposed just a bit from fully closed, and also whenever in a wide-open throttle. 

    You just need to adjust the switch so that this occurs, however, it is advisable to double-check with the ohmmeter. Combo-type sensors are normally adjusted just like the switch-type sensors.

    However, setting up potentiometer-type sensors will need the usage of a voltmeter. And you will also require the service manual to know the exact voltage spec, and the correct wires so that you can connect them up. Remember that this type of sensor is normally set up while ignition is on, engine off.

    Once you are with your service manual and correct tools, trying to adjust the throttle position sensor will lead to a better car running, more efficient engine life.

    Note that your vehicle’s throttle body injector helps in controlling the throttle and helps in maintaining the Vehicles revolutions per minute (RPM). Also, vehicles Motors makes use of the Vehicles in the same way as most automobiles. 

    So to adjust any throttle position sensor (TPS) of the Vehicles, this is what you should do, just remove the Vehicles and alter its makeup slightly.

    Note that turning the TPS down might help in improving the way your Vehicles performs, but if you turn it too low, then the Vehicles may not start.

    This is because adjusting the Vehicles requires a particular movement and should only be done by a professional who knows Vehicle engines very well.

    You can just remove the air cleaner lid and the air duct that leads to the throttle body by using the Phillips screwdriver. Just pull the air duct off the throttle body.

    After which, stick the pin in the center wire of your car throttle position sensor plug.

    Now you can connect the voltmeter red lead to this pin and then place the black lead on a good engine ground. Just loosen the two screws that secure the sensor to the throttle body by using the Phillips screwdriver.

    You can now turn the ignition key on but do not start the engine. Now rotate the sensor left or right until the voltmeter reads 0.50 volts. Then tighten the two bolts together in the sensor so it won’t move again. 

    Then pull the pin out of the wire on the sensor. You can now install the air cleaner duct and tighten it with the Phillips screwdriver.

    Here are the items you will need:

    1. A voltmeter
    2. Phillips screwdriver
    3. A needle

    One of the easiest methods to adjust your throttle position sensor is to unhook your battery’s negative cable from the battery for at least five minutes or to remove the fuse of your engine control module.

    However, you shouldn’t do this if you are not comfortable working with electricity, as if you remove the wrong fuse or cable from your car battery it could be dangerous for you. 

    Remember that adjusting your car throttle position sensor is sometimes all that is needed to restore your sensor.

    Sometimes error codes can cause your throttle position sensor to work incorrectly. However, you will need the service of professional software to reprogram your sensor. Please note that this job is best done by a professional mechanic around you.

    However, if your sensor requires just repairs, this could be the result of bad or loose wires. Like every other electrical wiring, your throttle position sensor can still have the wrong connections.

    But once you have observed that the issue is with your sensor, meaning it’s not a programming fault, then examine the wiring and connection area before you buy a new one.

    Before doing this, ensure that the accelerator pedal is fully released. Then turn the ignition switch “ON” and then wait for at least 2 seconds.

    Now turn the ignition switch “OFF” and wait for at least 10 seconds. Then turn the ignition switch “ON” and then wait for another 2 seconds.

    Please note that timing is critical for this to work for you. 

    1. Start by turning your ignition switch to on. Meaning, you shouldn’t start the engine! 

    2. You now wait for 3 seconds. 

    3. Now fully depress and release your vehicle accelerator pedal 5 times within 5 seconds. 

    4. Now wait for 7 to 10 seconds. 

    5. Then fully depress the accelerator pedal for about 10 seconds. Once you do this, the check engine light will start to blink quickly which indicates Diagnostic Test Mode II (Self-diagnostic results) has started. 

    6. Now release the accelerator pedal and wait for about 5 to 10 seconds. 

    7. Next, depress the accelerator pedal fully for about 10 seconds. Once done, the check engine light will change to blinking slowly which will indicate “Erasing ECU Memory”. 

    8. Now release the accelerator pedal and then turn the ignition switch to off. 

    9. You can now restart your engine. By now your check engine light should be out. 

    Please note: Once your car checks the engine light doesn’t blink as it is described in steps 5 & 7, it means the ECU isn’t reset yet. 

    However, if the steps above didn’t work, just disconnect the battery negative and then pump the brake to discharge the ECU capacitors. Note that this method is almost foolproof as long as all ECU control parameters are still within their normal ranges.
