TP SENSOR SIGNAL CIRCUIT(S) SHORT TO VOLTAGE
With the ignition off.
Disconnect the PCM C3 harness connector.
Note: Check connectors — Clean/repair as necessary.
Turn the ignition on.
Measure the voltage on the TP Sensor Signal 1 and the TP Sensor
Signal 2 circuits at the Throttle Body harness connector.
Is the voltage below 1.0 volt?
Yes >> Go To 13
No >> Repair the TP Sensor Signal circuit(s) for a short to volt-
age.
Perform POWERTRAIN VERIFICATION TEST - VER 2.
13.
CHECK THE TP SENSOR SIGNAL CIRCUITS FOR A SHORT TO OTHER CIRCUITS
Turn the ignition off.
Measure the resistance between the TP Sensor Signal 1 circuit and all
other circuits in the Throttle Body harness connector.
Measure the resistance between the TP Sensor Signal 2 circuit and all
other circuits in the Throttle Body harness connector.
Is the resistance above 100 kohms for all measurements?
Yes >> Go To 14
No >> Repair the circuits that measured below 100 kohms for a
short together.
Perform POWERTRAIN VERIFICATION TEST - VER 2.
