GPD 1811908 Ignition Knock Detonation Sensor

The GPD 1811908 is a direct-fit replacement ignition knock sensor, also known as a detonation sensor, engineered to restore proper engine management function. The knock sensor is mounted on the engine block, cylinder head, or intake manifold and continuously monitors for abnormal vibrations caused by engine pre-ignition or detonation (knock).

When the engine's ECU detects a knock signal, it retards ignition timing to protect the engine from damage. A failed or faulty knock sensor can trigger a check engine light, reduce fuel efficiency, and leave the engine vulnerable to detonation damage — making prompt replacement essential.
