To find the location, you must know the specific engine displacement (e.g., 4.8L, 5.3L) of your truck. Once you know the engine, you can:
* Consult a repair manual: A Haynes or Chilton repair manual specific to your year and engine will show you a diagram and precise location. This is the most reliable method.
* Use a online repair database: Sites like AllDataDIY or Mitchell 1 (subscription required) provide detailed diagrams and information.
* Search online forums: Search forums specific to your year and engine (e.g., "2001 Chevy Silverado 5.3L knock sensor location"). Be aware that information found online can be inaccurate, so always cross-reference with other sources.
Without knowing your specific engine, providing a precise location is impossible.
