Your cart is empty.An ACDelco GM Original Equipment Ignition Knock (Detonation) Sensor monitors the engine for pinging or spark knock, and is a GM-recommended replacement for your vehicle’s original component. 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 original equipment ignition knock sensor has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Good price on a genuine part. Solved my P0330 code on my 2015 Silverado 2500 6L gas. For anyone wondering, sensors moved from under the manifold to the outside of the engine on 15-19s. Passenger side is pictured, just behind the starter under a silver cylindrical protective cover. Little tight in here but nothing needs to be removed to swap it. The little red locking tab on the harness will probably break but it's not an issue. Torque is 18ftlb.

My CEL came on for a passenger side knock sensor on my 2016 Silverado 2500HD 6.0. There are two sensors located on either side of the block. Bank 1 drivers side bank 2 passenger side. See photo for passenger side (next to starter). Perfect fit. Excellent price. Took about 5 minutes to change out. Drove for a day or two and my CEL went off. Passed emissions. Perfect ðŸ‘

Codes came on my 2009 sierra 2500. Changed both sensors, cleared codes and runs well again.

Semble être une vrai pièce ACDelco fait au Japon, pas une copie ''chinoise''. Installé sur un GMC Yukon 6.2L 2007-2014 depuis 1 mois et tout est parfait. Le sensor défectueux donnais un code P0325-00 Knock Sensor circuit low voltage bank 1. J'ai changer les 2 sensor pour avoir la paix pour un bout. Bon prix et livraison en 2 jours.
