Any ideas why my 04 Optima V6 keeps blowing Throttle Position Sensor
Over the last 6 weeks I have replaced, Mass Air Flow sensor, Throttle Body, Crank Sensor, and the Throttle Position Sensor. But the TPS keeps going out, I have put 5 in during that time. the longest that it lasted was 2 weeks, twice it went out within 24 hours of replacing it. This has all happened since replacing the motor after a blown Timing belt. The first time it happened was the day after replacing the motor. The motor is out of an 03 Optima.(and I had the guy put a new Timing belt in it) so I wouldn't have to worry about it again. All of the sensors were brand new. ANY IDEAS???? I'm at my wits end!!!!
It sounds like there is a short to power on the TPS circuit , a live data scan should be able to tell you if it is a circuit problem or and ECM problem.
