GPD 1811946 Ignition Knock Detonation Sensor

The GPD 1811946 is a direct-fit 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, where they monitor for abnormal vibrations caused by engine pre-ignition or detonation — conditions that can lead to serious engine damage if left unaddressed.

When the sensor detects knock or ping, it sends a signal to the ECU, which retards ignition timing to protect the engine and optimize performance. A faulty knock sensor typically triggers a check engine light and may result in reduced power, poor fuel economy, or engine damage over time.
