Air Gap Inspection

Verify that the CKP sensor is securely installed.
Using a thickness gauge, measure the air gap between the plate projections at the back of crankshaft pulley and the CKP sensor.
- If not within the specification, inspect the plate projections for cracks or bending.
  - If there is any malfunction, replace the Crankshaft pulley.
