ACDelco GM Original Equipment Ignition Knock (Detonation) Sensors monitor the engine for pinging or spark knock, and are GM-recommended replacements for your vehicle's original components. These sensors create a voltage signal based on the vibrations caused by erratic air/fuel mixture combustion; the engine control module uses these signals to adjust the ignition timing and air/fuel mixture. These original equipment ignition knock sensors have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Product Features:
  • Sends signals to the engine control module (ECM) to adjust timing
  • Helps prevent damage to the engine caused by pre-ignition
  • GM-recommended replacement part for your GM vehicle's original factory component
