GPD Ignition Knock Detonation Sensor

The GPD Ignition Knock (Detonation) Sensor is a replacement engine knock sensor. It detects abnormal combustion vibrations (engine knock or detonation) and sends a signal to the engine control module. The ECM can then adjust ignition timing to protect the engine and keep it running smoothly.

Key Features:

• Monitors engine vibration and reports knock events to the engine computer
• Helps the ECM retard ignition timing to reduce the risk of detonation damage
• Supports fuel efficiency, smooth performance, and emissions control
• Built as a direct replacement for the original sensor
• Designed for durable operation in the heat and vibration of the engine environment

A failing knock sensor can cause a check engine light, reduced power, poor fuel economy, hesitation, or audible pinging. Replacing it restores proper engine protection and timing control. GPD offers this sensor line in multiple part numbers, so choose the one that matches your application.
