The camshaft position sensor (CMP sensor) on a 1992 Chevy S10 with the 4.3L V6 engine is located on the
passenger side of the engine, usually on the
front of the distributor. It's mounted near the distributor and often sits fairly close to the cylinder head. You might need a light and possibly a mirror to see it clearly.
Because of the age and potential variations, it's always best to double-check your specific engine's layout using a repair manual or a diagram for that year and engine. A diagram specifically showing the sensor location will give you the most accurate placement.
