Knock sensor location

Hi and thanks for using 2CarPros. Com

The only engine I am seeing available for all models of the Deville is a 4.6L V8. If you have something different, you will have to let me know.

The first picture I attached is the location of the knock sensor. There are two. They are located on the lower left side of the engine block. When looking at the picture, locate numbers 4 and 5.

_____________

Here are the directions for replacing them. Picture 2 correlates with these directions.

Removal Procedure

1. Raise the vehicle. Refer to Vehicle Lifting.

2. Remove the knock sensor harness connector (4).
3. Remove the knock sensor retaining bolt (3).
4. Remove the appropriate knock sensor (1 or 2).

Installation Procedure

Notice: Refer to Component Fastener Tightening Notice.

1. Install the knock sensor (1 or 2) and the bolt (3).

Tighten the sensor to 25 N.M (18 lb ft).

2. Connect the knock sensor harness connector (4).
3. Lower the vehicle.
