To find it, you'll need to:
1. Identify your specific vehicle: Year, make, and model are crucial.
2. Consult a repair manual: A Haynes, Chilton, or factory service manual for your specific vehicle will have diagrams showing the exact location of the CMP sensor. These manuals are your best resource.
3. Use an online parts diagram: Many auto parts websites (like AutoZone, Advance Auto Parts, etc.) allow you to select your vehicle and view diagrams of its engine components. Look for diagrams labeled "engine" or "camshaft."
General Possibilities: The sensor is usually found near the front of the engine, somewhere on or near the camshaft housing. Common locations include:
* On the top of the camshaft housing: This is a frequent location.
* On the side of the camshaft housing: Less common, but possible.
* Integrated into the distributor (older engines): If your 4.6L has a distributor, the sensor might be inside.
Without knowing the exact year and make of your vehicle, giving a precise location is impossible. Always consult your vehicle's repair manual or a parts diagram.
