Visual Inspection

  1. Disconnect the negative battery cable.
  2. Remove the CMP sensor. (See CAMSHAFT POSITION (CMP) SENSOR REMOVAL/INSTALLATION ).
  3. Verify that there are no metal shavings on the sensor.
    • 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".
