Where is the knock sensor located on a 1992 Chevy s10 blazer with 4.3 V6 eng?

The knock sensor on a 1992 Chevy S10 Blazer with a 4.3L V6 engine is typically located on the passenger side of the engine block, near the distributor. It's usually bolted directly to the block itself, and often near or slightly below the oil filter.

However, the exact location can vary slightly depending on the specific engine configuration. It's best to consult a repair manual specific to your year and engine for a definitive location. A visual inspection, with the engine compartment cleaned for better visibility, is recommended. Look for a small, usually one-wire sensor with a threaded mounting.
