On a 1990 Chevy 454SS engine, the knock sensor is typically located on the engine block, near the oil pan. Specifically, it is situated on the driver's side, towards the rear of the engine, usually around the area where the block meets the transmission bell housing. It's a small sensor with a single wire connector. Make sure to consult the vehicle's service manual for exact location and specifications.
