Hello,

The knock sensor is located in the lower part of the engine block. Here is some diagrams (below) that will show you the location.

Tighten the knock sensor to 19 N.M (14 lb ft)

Knock Sensor (3.4L VIN E)On lower left rear of engine, below exhaust manifold.

Knock Sensor (Bank 1) (3.8L VIN K)On lower left side of engine, near starter.

Knock Sensor (Bank 2) (3.8L VIN K)On lower right side of engine.

(Check out the diagrams below)

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken
