ACDelco GM Genuine Parts Knock Sensors

4.66 out of 5 stars 105 Customer Reviews

ACDelco GM Genuine Parts knock sensors are the GM recommended replacement for the vehicles original component. They monitor the engine for pinging or spark knock. The sensors create a voltage signal based on the vibrations caused by erratic air/fuel mixture combustion. The engine control module then uses that signal to adjust the ignition timing and air/fuel mixture. These GM Genuine Parts knock sensors have been manufactured to fit your GM vehicle, providing you with the same performance, durability, and service life you have come to expect from General Motors.
