Removal And Installation: Installation

NOTE:

The forward sensor is known to the Powertrain Control Module (PCM) as knock sensor 1, the rear sensor is known to the PCM as knock sensor 2.

  1. Thoroughly clean the knock sensor mounting holes.
    NOTE:

    Over or under tightening the sensor mounting bolts will affect knock sensor performance, possibly causing improper spark control. Always use the specified torque when installing the knock sensors.

    NOTE:

    There may be a foam strip on the bolt threads. This foam is used only to retain the bolts to the sensors for plant assembly. It is not used as a sealant. Do not apply any adhesive, sealant or thread locking compound to these bolts.
