Generally, on most Dodge Ram 1500 engines of that era, the CMP sensor is located on the passenger side (right side) of the engine, near the front of the cylinder head, but its exact position varies based on the engine. It's often mounted directly to the cylinder head or on the valve cover.
To locate it accurately:
1. Identify your engine: Check your vehicle's paperwork or look for an engine code stamped on the engine block.
2. Consult a repair manual: A repair manual specific to your year and engine will have diagrams showing the exact location of the CMP sensor and other components. This is the most reliable method.
3. Use an online parts diagram: Many auto parts websites (like AutoZone, Advance Auto Parts, etc.) allow you to enter your vehicle's information and view diagrams of the engine. Look for the CMP sensor in the diagrams.
Caution: Working on your vehicle's engine can be dangerous. If you are not comfortable performing this task yourself, it's best to take your vehicle to a qualified mechanic.
