The camshaft position sensor (CMP sensor) on a 1995 Dodge 2500 with the 3.9L engine is located on the
passenger side of the engine, on the front of the cylinder head. It's usually near the distributor (if equipped) and points towards the crankshaft. You'll likely find it near the timing chain cover.
However, it's best to consult a repair manual specific to your vehicle year and engine. A diagram will show the exact location and help you avoid confusion with other sensors in the area. A picture search online for "1995 Dodge 2500 3.9L camshaft position sensor location" might also be helpful.
