Where is the knock sensor located on a 3.5 aurora engine?

The knock sensor on a 3.5L Aurora engine (typically found in Buick, Pontiac, and Saturn vehicles) is located on the engine block, near the cylinder head. However, the precise location varies slightly depending on the year and specific engine variant.

To find it definitively, you'll need to:

* Consult your vehicle's repair manual: This is the most reliable source. The manual will have diagrams showing the exact location of the knock sensor.

* Use a repair database: Sites like AllDataDIY, Mitchell 1, or others will provide diagrams and information specific to your vehicle's year and model.

* Look for a small, one-wire sensor: It's usually a relatively small sensor with a single wire connector near the engine block, often near the oil filter or in the vicinity of the exhaust manifold. You'll likely need to be fairly familiar with your engine compartment to spot it visually.

Caution: Do not attempt to locate or work on this sensor without the proper tools and knowledge. Improper handling can damage the sensor or other parts of the engine.
