Test Description

The numbers below refer to the step numbers in the diagnostic procedures.

1. 2
   
   This step verifies that the malfunction is present.
2. 3
   
   This step tests for electro-magnetic interference (EMI) on the CMP sensor circuits.
3. 6
   
   Damage to the reluctor wheel can affect the CMP sensor output. Vertical lines across the face of the sensor may indicate foreign material passing between the CMP sensor and the reluctor wheel. This condition can cause this DTC to set. If damage to the sensor is evident, replace the CMP sensor.
