GPD Ignition Knock Detonation Sensor with Wiring Harness

The GPD ignition knock sensor (also called a detonation sensor) with wiring harness helps your engine management system detect abnormal combustion and engine knock. The sensor monitors vibration in the engine block or cylinder head 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:

• Detects engine knock and detonation so the ECM can adjust timing
• Includes a wiring harness or connector for plug-in installation
• Built to meet the performance and durability expected of a replacement sensor
• Helps maintain fuel economy, drivability, and engine protection

A failing knock sensor can cause a check engine light, reduced power, poor fuel economy, hesitation, or engine pinging. Replacing it with a GPD sensor helps restore proper engine control feedback. Select the correct part number for your application from the variants listed on this page.
