VDO Gauges Ignition Knock Detonation Sensor

The VDO Ignition Knock (Detonation) Sensor line offers replacement knock sensors that monitor your engine for detonation, also called pre-detonation, engine knock or pinging. When the sensor detects knock vibrations, it sends a signal to the engine control unit. The ECU can then adjust ignition timing and fuel delivery to protect the engine.

Key Features:

• Detects engine knock: picks up the vibrations caused by abnormal combustion and sends an electrical signal to the engine management system.
• Helps protect the engine: prolonged detonation can damage pistons, cylinder walls, the head gasket, spark plugs and valves, and early detection helps prevent that.
• Supports performance and efficiency: accurate knock feedback lets the ECU keep ignition timing optimized for smooth running.
• Quality construction: built with durable metal and plastic components for reliable, long-term operation.
• Trusted brand: VDO, part of the Continental/Siemens family, is known for automotive sensors, instruments and electronic components.

A failing knock sensor can trigger a check engine light, so replacing it promptly helps restore proper engine management. Choose the individual part number that matches your application from the options on this page.
