Component Test
- Inspect the CMP sensor for looseness and correct installation.
- Connect jumper wires from the CMP sensor connector 12-volt reference CMP sensor terminal C and the low reference CMP sensor terminal B to the CMP sensor. Turn ON the ignition, with the engine OFF.
- Connect a DMM to the CMP sensor signal CMP sensor terminal A at the CMP 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 CMP sensor.
