MEASURE THE RESISTANCE BETWEEN GROUND AND THE APP SENSOR 5-VOLT SUPPLY CIRCUIT
With the ignition off.
Disconnect the PCM C4 harness connector.
Note: Check connectors — Clean/repair as necessary.
Measure the resistance between ground and the APP Sensor 5-Volt
Supply circuit at the PCM C4 harness connector.
Is the resistance above 100 kohms?
Yes >> Go To 21
No >> Repair the APP Sensor 5-Volt Supply circuit for a short to
ground.
Perform POWERTRAIN VERIFICATION TEST - VER 2.

MEASURE RESISTANCE BETWEEN THE APP SENSOR 5-VOLT SUPPLY CIRCUIT AND SENSOR
GROUND CIRCUITS
With the ignition off.
Measure the resistance between the APP Sensor 5-Volt Supply circuit
and all Sensor Ground circuits in the PCM C4 harness connector.
Is the resistance above 100 kohms for all measurements?
Yes >> Go To 22
