Component Test
- Inspect the CKP sensor for looseness and correct installation.
- Connect jumper wires from the CKP sensor connector 12-volt reference and the low reference to the CKP sensor; turn ON the ignition, with the engine OFF.
- Connect a DMM to the CKP sensor signal at the CKP sensor and observe the Duty Cycle. Pass a steel object by the sensor repeatedly. The Duty Cycle should increment.
- If the Duty Cycle does not increment, replace the CKP sensor.
