Where is the crankshaft positioning sensor on a 2004 Chevy Silverado 5.3 liter v8?

On a 2004 Chevy Silverado 5.3L V8, the crankshaft position sensor (CKP sensor) is typically located on the passenger side of the engine block, near the front of the engine, below the oil filter. It's often mounted on the engine block itself, rather than on the bellhousing.

However, it's crucial to consult a repair manual specific to your vehicle's year and engine code. The exact location can vary slightly depending on the specific engine configuration and even minor manufacturing differences. A repair manual will have diagrams and precise instructions to avoid any mistakes. Don't rely solely on general information.
