Generally, on most 4.3L V6 engines (like those found in GM vehicles), the CMP sensor is located on the passenger side (right side) of the engine, either on the top of the valve cover near the camshaft, or sometimes on the front of the engine block, near the timing chain cover.
To find the exact location on *your* 4.3L engine, you should:
1. Consult your vehicle's repair manual: This is the most reliable source. The manual will have diagrams and specific instructions.
2. Use an online parts diagram: Websites selling auto parts (like AutoZone, Advance Auto Parts, etc.) often have online diagrams you can browse by entering your vehicle's year, make, and model. Search for "camshaft position sensor" or "CMP sensor."
3. Visually inspect the engine: Look for a sensor that's connected to a wiring harness and is positioned near the camshaft. It often has a single connector. Be careful not to touch hot parts of the engine.
Without knowing the specific vehicle, I cannot give you a more precise location. Always refer to your vehicle's specific documentation for the most accurate information.
