Component Testing
- Ignition OFF, disconnect the harness connector of the CKP sensor.
- Test for 500-700 ohms between the signal circuit and low reference circuit of the CKP sensor.
- If the resistance is not within the specified range, replace the CKP sensor.
- Disconnect the fuel pump relay.
- Set the DMM to the AC voltage scale.
- While cranking the engine, test for greater than 500 mVAC between the signal circuit and low reference circuit of the CKP sensor.
- If less than the specified value, replace the CKP sensor.
IMPORTANT:
If the CKP sensor lead is damaged in any way, replace the CKP sensor.
