Where is cam sensor located on 1989 Chevy truck?

The camshaft position sensor (CMP sensor) on a 1989 Chevy truck's engine depends heavily on the *specific* engine. Chevy trucks from that year used several different engines (small-block V8s, possibly a V6, and possibly even a diesel). The location varies significantly between these engines.

To find it, you'll need to:

1. Identify your engine: Look for an engine code (usually stamped on a metal plate on the engine block) or find the engine's specifications in your owner's manual. This code will let you look up the exact location of the CMP sensor.

2. Consult a repair manual: A repair manual specific to your year and engine will have diagrams showing the sensor's exact location. Haynes and Chilton are popular brands.

3. Search online with your engine code: Search online using terms like "[Your Engine Code] camshaft position sensor location." You might find images or forum posts showing its location.

Without knowing the specific engine, it's impossible to give a precise answer. The CMP sensor is usually located somewhere on the engine block near the distributor (if equipped) or the camshaft itself, but the exact positioning is engine-specific.
