Where is the cam shaft sensor on a 1989 Oldsmobile 88?

The exact location of the camshaft position sensor (CMP sensor) on a 1989 Oldsmobile 88 depends on the engine it has. Oldsmobiles of that year used several different V6 and V8 engines. There's no single answer.

To find it, you'll need to:

1. Identify your engine: Check your vehicle's paperwork or the engine bay itself for the engine displacement (e.g., 3.8L V6, 5.0L V8). This is crucial.

2. Consult a repair manual: Once you know the engine type, get a repair manual specific to your 1989 Oldsmobile 88 and that engine. The manual will have diagrams showing the location of all sensors, including the CMP sensor. Chilton, Haynes, and factory service manuals are good options.

3. Use online resources: Websites like AutoZone, Advance Auto Parts, and others often have diagrams and parts lookup tools. You'll need your engine code (if you can find it) for the most accurate results. However, these are often less detailed than a dedicated repair manual.

Without knowing your specific engine, it's impossible to give you a precise location. The sensor is usually located on the engine block near the distributor (if equipped) or near the camshaft gear, but its exact placement varies depending on the engine design.
