GPD Knock Sensor

The GPD Knock Sensor (also called a detonation sensor or ignition knock sensor) is a direct-fit replacement part for the engine management system. A knock sensor mounts on the engine block, cylinder head or intake manifold. It detects the unusual vibrations caused by engine pre-ignition or detonation. It sends that signal to the engine control module, which can then adjust ignition timing to help protect the engine and keep combustion running properly.

Key Features:

• Designed to meet or exceed OE fit, form and function
• Direct-fit replacement for a worn or failing knock sensor
• Tested for durability and performance
• Helps support accurate combustion monitoring and emission control system operation
• Professional-quality construction for long service life

Choose the part number that matches your application to get the correct connector style and sensor configuration. Replacing a failed knock sensor helps restore proper engine performance and efficiency.
