Component Test

  1. Inspect the CKP sensor for looseness and correct installation.
  2. Disconnect the CKP sensor connector. Connect jumper wires from the CKP sensor connector 12-volt reference CKP sensor terminal D and the low reference CKP sensor terminal C to the CKP sensor. Turn ON the ignition, with the engine OFF.
  3. Ignition ON, connect a DMM to the CKP sensor signal CKP sensor 1 terminal B 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.
