GPD 1812957 Ignition Knock Detonation Sensor Direct-Fit Replacement

The GPD 1812957 is a direct-fit aftermarket ignition knock sensor (also known as a detonation sensor) engineered to meet or exceed original equipment specifications. Designed as a reliable replacement for a worn or failed knock sensor, this part restores proper engine management function and helps protect against engine damage caused by uncontrolled detonation.

The knock sensor is mounted on the engine block, cylinder head, or intake manifold, where it continuously monitors for abnormal vibrations associated with pre-ignition and engine knock. When the ECM receives a signal from the sensor, it adjusts ignition timing to eliminate knock, optimizing both performance and fuel efficiency.
