Diagnostic Aids

The ECM compares the signal of each of the APP sensor to each other throughout the entire range of operation. Clear the DTCs and actuate the pedal through the entire range with the ignition ON and the engine OFF.
Use the J 35616 Connector Test Adapter Kit for any test that requires probing the ECM harness connector or a component harness connector. Using this kit will prevent damage to the harness connector terminals.
For intermittent conditions, refer to Testing for Intermittent Conditions and Poor Connections .
