- Ensure that the CKP sensor circuits are not routed too closely to the fuel injector wiring after-market add-on electrical equipment, solenoids, relays or motors.
- Ignition OFF, inspect the CKP sensor for correct installation.
- If the sensor is loose, inspect the sensor and the O-ring for damage, replace as necessary.
- Engine running, observe the CKP Sensor Signal Present parameter of the scan tool while manipulating the related harnesses, connectors, and wires of the CKP sensor. The parameter should display Yes.
- If the parameter displays No or fluctuates between Yes and No, inspect the related harness, connector, or wire for damage or poor connectivity at or near the point of the manipulation. Repair or replace as necessary.
- Inspect the engine for the following conditions:
- The engine oil for debris
- The crankshaft reluctor wheel for damage or foreign material passing between the sensor and reluctor wheel
- The timing chain, tensioner, and sprockets for wear or damage
- If no other condition is found, replace the CKP sensor.
