Air Gap Inspection

  1. Verify that the CKP sensor is securely installed.
  2. 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 plate.
      • If the monitor item condition/specification (reference) is not within the specification, even though there is no malfunction, carry out the "Circuit Open/Short Inspection".
