(P0120) ELECTRONIC THROTTLE CONTROL MOTOR PERFORMANCE (CONTINUED)
8.
CHECK THROTTLE CONTROL MOTOR CIRCUITS FOR A SHORT TO SENSOR GROUND CIRCUIT
With the ignition off.
Measure the resistance between the Sensor Ground circuit and the
Throttle Control Motor circuit(s) that measured below 3.1 volts.
Is the resistance above 100 kohms?
Yes >> Go To 9
No >> Repair the Throttle Control Motor circuit(s) for a short to
the Sensor Ground circuit.
Perform POWERTRAIN VERIFICATION TEST - VER 2.
9.
THROTTLE CONTROL MOTOR CIRCUIT(S) OPEN
With the ignition off.
Measure the resistance of the Throttle Control Motor 1 circuit from the
Throttle Body harness connector to the PCM C1 harness connector.
Measure the resistance of the Throttle Control Motor 2 circuit from the
Throttle Body harness connector to the PCM C1 harness connector.
Is the resistance below 5.0 ohms for both measurements?
Yes >> Go To 24
>>
Repair the Throttle Control Motor circuit(s) that measured above 5.0
ohms for an open.
Perform POWERTRAIN VERIFICATION TEST - VER 2.
