hi everyone
since i bought the car, couple of years ago, i have repeating problem with the TPS of high voltage. in the first time i bought new sensor and i had quiet for few months. when to problem returned i change back to the old sensor and again, unexpectedly, the problem solved for few months. since then the problem returns form time to time and i change between the sensors and it run ok.
today i tried to do it again but the tps voltage remain stuck on 5V. i checked the wires with volt meter and found that the input sign wire (j1-18) getting +5V from the ECM. i thought that maybe i have short in the TPS wiring so i disconnect the sign wire from the ECM and checked the voltage directly from the ECM pin and still got +5V.
ideas?
thanks
