How to Replace a Throttle Position Sensor

The throttle position sensor (TPS) is used to inform the powertrain control module (PCM) of throttle position. The PCM uses this information to determine control of various output devices, such as the fuel injectors, transmission shift solenoids, etc. Basically, the throttle position sensor is a variable resistor. Its internal resistance and output signal voltage change in relation to throttle position. Some common symptoms of a failed throttle position sensor include hesitation, poor acceleration, rough idle, increased emissions and an illuminated Check Engine Light.

I was very happy with my experience. He was prompt, knowledgeable, and did the job with no problems. However, my check engine light came on again after driving four miles, so I believe there is another problem not related to the service I received. Dan may hear from me again when I find out what's goin g on now. Thanks!
