The knock sensor on a 1998 Chevy S10 pickup is typically located on the
passenger side of the engine block, near the
front. However, the exact location can vary slightly depending on the engine (4.3L V6 or 2.2L I4). You'll likely find it near the oil filter or the distributor (if equipped).
To be certain, consult a repair manual specific to your vehicle's year, engine, and trim level. A diagram showing the sensor's location will be invaluable. You can find these manuals online or at auto parts stores.
