Re: throttle position sensor
HI did your car have (ETS) electronic throttle control system the TPSis a part of this system but you can test it by using diagnoses scan tool to check the TPS value when press or depress the accelerator pad. so you can tell us the NO. of DTC for example(P0122) ASK FOR MORE INFORMATION

Here are a couple of suggestions, check the throttle position sensor. The TPS circuitry can wear over time, whether it is the sensor body itself or its outboard circuits, and can stick in a "run" position when you put your vehicle into park. The result is a high-rev situation. Make sure the neutral-start switch is also working correctly as it, in combination with the TPS, can also cause this type of condition.
No, actually I would find a different Mechanic. 2000 and newer the TPS, Throttle Position Sensor, is pretty much standard to control idle RPM. Even in Fuel injection, it is just located on an Air control valve instead of a Carburetor.
I'm not exactly sure with out more info.Do you have a check engine light on. This could be caused from several different sensors. The mas air flow sensor controls how much fuel is injected into the engine.So that is one possibility. It could be your O2 sensor or possibly even your throttle positioning sensor.I really need a little more info.
Go to Auto Parts Store and purchase TPS Sensor.
Only if you know that is your vehicles problem.
Codes alone, don't always tell you what is wrong, and what to replace.
Most people are starting to believe it's that simple.
if the code keeps comming back then you would first find the wire that goes from the tps to the computer. check for the five volt reference voltage, at the computer and at the tps and then check to see if the return voltage is also at the computer. ( this wire sometimes breaks)
