GPD 1815037 Ignition Knock Detonation Sensor

The GPD 1815037 is a direct-fit replacement ignition knock sensor, also known as a detonation sensor, designed to restore proper engine management function. Knock sensors are mounted on the engine block, cylinder head, or intake manifold and play a critical role in protecting your engine from damage caused by pre-ignition or detonation.

The sensor detects abnormal engine vibrations associated with knock or ping events and sends a signal to the engine control module (ECM), which then adjusts ignition timing to prevent engine damage. A failed or faulty knock sensor will typically trigger a check engine light and can result in poor fuel economy, reduced performance, and long-term engine wear if left unaddressed.
