Where is cam sensor on dodge ram truck 1991?

On a 1991 Dodge Ram, the camshaft position sensor (CMP sensor) location varies slightly depending on the engine. You'll need to specify the engine size (e.g., 3.9L, 5.2L, 5.9L) to get a precise answer.

However, generally, the CMP sensor is located on the front of the engine, near the distributor (if equipped) or the timing cover. It's usually mounted on the engine block itself, and its location will be near the camshaft gear. It's a relatively small sensor, often with a single wire connector.

To find it definitively:

1. Consult a repair manual: A Haynes or Chilton manual specific to your year and engine will show you exactly where the sensor is located. This is the most reliable method.

2. Use a parts diagram: Many online auto parts stores (like AutoZone, Advance Auto Parts, etc.) have online parts diagrams you can browse using your vehicle's year, make, model, and engine. Searching for "camshaft position sensor" will likely highlight its location in the diagram.

3. Visual Inspection (Use caution): Once you've identified the general area (front of engine, near timing cover/distributor), carefully examine the engine block and surrounding components. Look for a small sensor that looks like it might be connected to the camshaft timing mechanism.

Important Safety Note: Before working on your engine, always disconnect the negative battery terminal. Be aware of moving parts and hot surfaces. If you are not comfortable performing this task yourself, it is best to consult a qualified mechanic.
