I had my car scanned at AutoZone due to my check engine light staying on. It came up that I need a knock sensor. I need to know where it is located and how to put a new knock sensor on to save labor charges. My friend is replacing it for me tomorrow and my car listed above is the SS Series 2.

Good afternoon,

What was the code number? It may or may not be the sensor. Codes rarely identify part failures, just system failures.

The procedure below and a picture.

1. Turn Off the ignition.
2. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in Vehicle Lifting.
3. Remove the splash shield.
4. Drain the cooling system. Refer to Draining and Filling Cooling System in Cooling System.
