Where is the crankshaft sensor located on a 1987 Chevrolet celebrity 2.8?

On a 1987 Chevrolet Celebrity with the 2.8L V6 engine, the crankshaft position sensor (CKP sensor) is typically located on the passenger side of the engine block, near the bellhousing where the engine connects to the transmission. It's usually mounted on the engine block itself and points towards the crankshaft's reluctor wheel.

However, without a visual inspection of your specific engine, this is only a general location. A repair manual specific to your vehicle year and engine would be the most accurate source to confirm its exact location. A picture search online for "1987 Chevrolet Celebrity 2.8L crankshaft position sensor location" may also yield helpful visual results.
