NOTE: The left sensor is identified by an identification tag (LEFT). It is also identified by a larger bolt head. The Powertrain Control Module (PCM) must have and know the correct sensor left/right positions. Do not mix the sensor locations.

Disconnect knock sensor dual pigtail harness from engine wiring harness, this connection is made near rear of left valve cover ( Fig 1 ).
Remove intake manifold. Refer to INTAKE MANIFOLD .
Remove sensor mounting bolts ( Fig 1 ). Note foam strip on bolt threads. This foam is used only to retain the bolts to sensors for plant assembly. It is not used as a sealant. Do not apply any adhesive, sealant or thread locking compound to these bolts.
Remove sensors from engine.
