An ACDelco Professional, premium aftermarket Ignition Knock (Detonation) Sensor is the ideal high quality replacement for your GM vehicle. It monitors the engine for pinging or spark knock. The sensor creates a voltage signal based on the vibrations caused by erratic air/fuel mixture combustion; the engine control module uses this signal to adjust the ignition timing and air/fuel mixture. This premium aftermarket replacement ignition knock sensor is manufactured to meet or exceed your expectations for fit, form, and function.
