This sensor is a kind of potentiometer which transforms the throttle position into output voltage, and emits the voltage signal to the Engine Control Module (). Throttle Position Sensor Replacement Hey all, I purchased my car with 99k on it and recently completed the replacement of all belts pulleys, water pump, thermostat, plugs and coolant and cleaned the throtte body. When the throttle position sensor is repaired or replaced, it will need to have the minimum idle speed reset to factory specs, and the trouble codes will need to be cleared. The ECM is a type of electronic control unit (ECU), which is an embedded system that employs software to determine the required throttle position by calculations from data measured by other sensors, including the accelerator pedal position sensors, engine speed sensor, vehicle speed sensor, and cruise control switches. 1) In order to read the code the battery must be 11v or higher, throttle valve fully closed, transmission in neutral position, and AC turned off. Searching the p1239 code, it pulls up posts where some people suggest replacing the throttle PEDAL sensor at the base of the gas pedal. I found a forum post that recommended lubricating the throttle position sensor internal wipers. Don't sweat it. During the reset procedure the display will count from 0 to 9. If the TPS sensor is your problem, you will need to reset your ECM after replacing. Great! However, that was last week. I had to change the whole throttle body out because the TPS is connected to it. u but still have an awful misfire on occasion at idle. When the codes were reset, it shifted normally again. My issue is that I am not sure how to test the Throttle Position Sensor to see if it is ok or if it is a wiring issue. This sensor is a kind of potentiometer which transforms the throttle position into output voltage, and emits the voltage signal to the Engine Control Module (). As such they lack a mechanical carburetor and instead split the function of the carburetor into three parts, namely the Air Flow Meter in the air cleaner box, the throttle body and the fuel injector. i have a similar problem to original post i have a black 99 xr6 its just had o2 sensor bosh super 4 plugs and full reset of e. We were having to clean it roughly every 3-4 weeks at first and then more frequently as time went on until it wouldn't last long enough to get to the end of the driveway. The sensor is usually located on the butterfly spindle/shaft so that it can directly monitor the position of the throttle. Some forum users are using a clever method to reset their Throttle Position Sensor (TPS) and get more throttle response. Warm up the engine to its normal operating temperature (the engine requires extra air and fuel when cold). Another weak point is the throttle position sensor. Car won't accelerate, lacks power when accelerating, or accelerates itself. That pot is part of the throttle control! You might be able to reset the throttle sensor, turn key to on position and pump pedal 4-5 time from 0 -100% then back off and then start engine. Any of the TPS codes; test out the Throttle Position Sensor both at the sensor and at the ECU connector, Also make sure the TPS connector is tight. Align the TPS pickup lever with the tang on the throttle actuator lever (TPS drive lever on the throttle shaft). Throttle Position Sensor? I've read a few threads from way back (2005) about a possible faulty TPS. The engine just stays at low revs. There is a screw (might be torx, can't remember) holding it in place. P0122 Description The throttle position sensor responds to the accelerator pedal movement.
