Where is the location of a crankshaft sensor on Chevy S-10 1994 4.3?

On a 1994 Chevy S-10 with the 4.3L V6 engine, the crankshaft position sensor (CKP sensor) is typically located on the passenger side of the engine block, near the rear of the engine, close to the bellhousing. It's often mounted on the engine block itself, pointing towards the flywheel.

However, the exact location can vary slightly depending on specific engine variations. It's best to consult a repair manual specific to your 1994 Chevy S-10 4.3L engine for a precise diagram and location. A visual inspection with the engine bay somewhat clear will also help, looking for a sensor near the described location that has a single wire connector.
