The TPS is good, and checked the wiring and the voltage is low, do the wires for the TPS run direct to the ECM? the wiring is fine from the firewall to the TPS but not sure which ones are inside the vehicle for me to test. So could it possibly a faulty ECM?
TPS not mounted securely.
TPS circuit short to ground or another wire.
Faulty TPS.
Damaged computer (PCM).
to fix this code you can try this:
Carefully check the throttle position sensor (TPS), wiring connector, and wiring for breaks, etc. Repair or replace as necessary
Check the voltage at the TPS (refer to a service manual for your vehicle for specific information). If the voltage is too low that is indicative of a problem. Replace if necessary.
If recently replaced the TPS may need to be adjusted. On some vehicles the installation instructions call for the TPS to be properly aligned or adjusted, consult a repair manual for specifics.
If there are no symptoms at all, the problem may be intermittent and clearing the code may resolve the issue temporarily. If this is the case then you should definitely check the wiring to be sure it's not rubbing on anything, grounding, etc. The code may come back.
