41 Throttle Position Sensor Signal
Diagnosis:
* Open or short circuit in throttle position sensor signal.
Trouble Area:
* Throttle position sensor circuit
* Throttle position sensor
* ECU
When it says "circuit," it is referring to the wiring from the sensor to the ecu. Most common problem is that the connector is loose, the wires are pulling out of the connector, or the insulation on the wires is deteriorating, and two wires are randomly touching. It's the first thing I always check.
Have you tested the tps with the volt. readings I gave you? With + on VTA, and neg. on E2, slowly open the throttle to wot(key on, engine off). If there is a dead spot(a spot that suddenly reads 0, then continues on normally), then the sensor is bad. If not, and the readings don't match the readings I listed above, it needs to be adjusted.
