Information:
position sensor is a PWM sensor. The sensor operates at a frequency of 5000 Hertz. The duty cycle is proportional to the position of the pedal. The duty cycle will operate from a range of approximately 10% to 90%. The possible causes of this diagnostic code are listed below:
The sensor has failed.
The signal circuit of the sensor is shorted to the + battery circuit.
The sensor needs to be calibrated.
The ECM has failed. This is unlikely.Note: The following test procedure may create other diagnostic codes. Ignore these created diagnostic codes and clear the diagnostic codes when the original diagnostic code has been corrected.Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.Test Step 1. INSPECT THE SENSOR
Perform a visual inspection of the sensor, the wiring for the sensor and the hardware that is associated with the sensor.Expected Result:There is no apparent damage to the sensor, the wiring for the sensor or the hardware that is associated with the sensor.Results:
OK - There is no apparent damage to the sensor, the wiring for the sensor or the hardware that is associated with the sensor. Proceed to Test Step 2.
NOT OK - There is apparent damage to the sensor, the wiring for the sensor or the hardware that is associated with the sensor.Repair: Replace the damaged part. Proceed to Test Step 8.Test Step 2. CHECK FOR POWER AT THE SENSOR
Do not disconnect the harness connector from the sensor.
At the back of the harness connector for the sensor, insert a 7X-1710 Multimeter Probe along the voltage supply wire (contact A).
Turn the key start switch and the disconnect switch
