Camshaft Position (CMP) Sensor Removal/Installation

  1. Remove the battery cover.
  2. Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [LF] .)
    CAUTION:
    • When replacing the camshaft position sensor, make sure there are no metal shavings adhering as they can cause the sensor output signal to malfunction from fluctuation in magnetic flux resulting in a deterioration in engine control. Cover a removed CMP sensor in plastic to protect it from foreign material adhering to it.
  3. Disconnect the CMP sensor connector.
  4. Remove the CMP sensor installation bolt.
  5. Remove the CMP sensor from the cylinder head cover.
