The Engine Control Module (ECM) detects the following conditions:
•The signal frequency from the accelerator pedal position sensor is less than 150 Hz or the signal frequency is greater than 1050 Hz for more than two seconds.
•The ECM has been powered for at least three seconds.
Probable Causes:
1) ECM Connection/Harness
2) Accelerator Position Sensor
3) Accelerator Position Sensor Harness
4) ECM Failure
