TP SENSOR SIGNAL CIRCUIT(S) OPEN
With the ignition off.
Measure the resistance of the TP Sensor Signal 1 circuit from the
Throttle Body harness connector to the PCM C3 harness connector.
Measure the resistance of the TP Sensor Signal 2 circuit from the
Throttle Body harness connector to the PCM C3 harness connector.
Is the resistance below 5.0 ohms for both measurements?
Yes >> Go To 15
No >> Repair the TP Sensor Signal circuit(s) for an open.
Perform POWERTRAIN VERIFICATION TEST - VER 2.
15.
MEASURE THE RESISTANCE BETWEEN GROUND AND THE TP SENSOR SIGNAL CIRCUITS
With the ignition off.
Measure the resistance between ground and the TP Sensor Signal 1
circuit at the Throttle Body harness connector.
Measure the resistance between ground and the TP Sensor Signal 2
circuit at the Throttle Body harness connector.
Is the resistance above 100 kohms for both measurements?
Yes >> Go To 24
No >> Repair the TP Sensor Signal circuit(s) for a short to
ground.
Perform POWERTRAIN VERIFICATION TEST - VER 2.
