Resistance Inspection

  1. Disconnect the negative battery cable.
  2. Disconnect the CMP sensor connector.
  3. Measure the resistance between the CMP sensor terminals A and B using an ohmmeter.
    • If the CMP sensor is okay, but the PID value is out of specification, perform the "Circuit Open/Short Inspection".
    • If not as specified, replace the CMP sensor. (See CAMSHAFT POSITION (CMP) SENSOR REMOVAL/INSTALLATION ).
