The knock sensor on a 1986 Pontiac Firebird with a V8 305 CI engine is typically located on the engine block, near the oil filter or on the side of the engine. It is usually positioned to detect vibrations caused by engine knock or pre-ignition. To access it, you may need to remove some components, as it can be somewhat hidden. Always refer to a service manual for specific details on your vehicle's layout.
