Vehicle: 2002 Hyundai XG350 L
Today while driving to work on the Interstate, my check engine light clicked on and suddenly my gas pedal seemed to just stop working. I managed to coast off an exit and stop near a service station. The mechanic hooked it up and it showed a problem with the Throttle Position Sensor.
However, immediately after turning off and restarting the car, it starts up and seems to just run fine. I've had numerous other strange electrical-type problems with this car, and I worry that the TPS failure is just the latest victim (or symptom, rather).
Are there any other reasons the TPS might report a problem during a diagnostic? If it IS a bad TPS, why would it just stop working althogether, and then start working again once I restart the car?
