    vehicle have two knock sensors
    bank 1 on passenger side
    bank 2 on driver side

    BANK 1:

    REMOVAL PROCEDURE
    Disconnect the knock sensor from the wiring harness.
    Remove the generator and the drive belt tensioner.

    IMPORTANT: The knock sensor pigtail is guided past the rear timing belt cover by several retaining clips. Only one retainer clip is shown. Note the positioning of the knock sensor pigtail.

    Remove the knock sensor pigtail from the retaining clips on the rear timing belt cover.
    Remove the bolt in the center of the knock sensor.
    Remove the knock sensor (1) from the engine block.

    INSTALLATION PROCEDURE
    Thoroughly clean the mating surfaces of the knock sensor and the engine block. The entire contact surface of the knock sensor must lie directly on the engine block.
    NOTE: Refer to Fastener Notice in Service Precautions.

    IMPORTANT: Do not use washers, spring washers, or toothed washers when installing the knock sensor. Tighten all of the fasteners to the proper torque.

    Install the knock sensor (1) on to the engine block.
    Tighten
    Tighten the sensor to 20 N.m (15 lb ft) .

    IMPORTANT: The knock sensor pigtail is guided past the rear timing belt cover by several retaining clips. Only one retainer clip is shown. Install the knock sensor pigtail as noted during removal.

    Install the knock sensor pigtail into the retaining clips. Ensure that the pigtail does not contact any moving parts.
    Install the generator and the drive belt tensioner.
    Connect the knock sensor connector.


    BANK 2:

    REMOVAL PROCEDURE
    Disconnect the knock sensor connector (1).
    Remove the power steering pump pulley.
    Remove the knock sensor pigtail from the retaining clips.
    Securely attach a scrap piece of wire about 36 inches long to the knock sensor pigtail. Later, this will be used as a pull wire to guide the new sensor pigtail back through the same routing.
    Remove the left hand engine mount.
    Remove the fastening bolts for the engine mount bracket and remove the bracket from the block.
    Remove the bolt from the center of the knock sensor.
    Gently pull the knock sensor pigtail through the wiring conduit and out. Stop when the pull wire is free of the conduit at both ends.
    IMPORTANT: Observe the routing of the pigtail for proper installation.

    Detach the knock sensor from the pull wire, leaving the pull wire in place.
    INSTALLATION PROCEDURE
    Thoroughly clean the mating surfaces of the knock sensor and the engine block. The entire contact surface of the knock sensor must lie directly on the engine block.
    NOTE: Refer to Fastener Notice in Service Precautions.

    IMPORTANT: Do not use any washers, any spring washers, or any toothed washers when installing the knock sensor. Tighten all of the fasteners to the proper torque.

    IMPORTANT: When routing the pigtail for the knock sensor, ensure that the pigtail does not contact the exhaust manifold or any moving parts and is correctly routed.
