True Tech Ignition Knock Detonation Sensor

The True Tech Ignition Knock Sensor, also called a detonation sensor or engine knock sensor, is a replacement part that monitors engine vibration. It helps the engine control module detect knock and adjust ignition timing to protect the engine.

Key Features:

• Detects engine knock: It senses the vibrations caused by detonation and sends a signal to the engine computer.
• Supports proper ignition timing: The engine computer uses the signal to retard timing when knock occurs, which helps prevent damage to pistons, rings and bearings.
• Replacement design: Built as a direct replacement for the original knock sensor in the applications it covers.
• Part-specific variants: Each part number in this line is made for its own application.

A failing knock sensor can cause a check engine light, poor performance, hesitation, reduced fuel economy or an emissions test failure. Replacing it restores the engine computer's ability to monitor knock and keep timing accurate. Always confirm the correct part number for your application before ordering.
