VDO Gauges Knock/Detonation Sensor

The VDO knock sensor, also called a detonation sensor or ignition knock sensor, is a replacement engine management component. It listens for the vibration of engine knock (pre-detonation) and reports it to the engine control unit. VDO has been a well-known name in vehicle instrumentation and sensors since 1929.

Key Features:

• Detects engine knock and detonation and sends an electrical signal to the engine computer
• Lets the engine computer adjust ignition timing and fuel delivery to stop knock
• Helps protect pistons, cylinder walls, cylinder head, head gasket, spark plugs and valves from damage caused by prolonged detonation
• Built from metal and plastic components for durability under engine heat and vibration
• Replacement-style design for straightforward installation

A working knock sensor helps the engine run smoothly and efficiently, and it can help avoid a check engine light caused by a failed sensor. Select the child item that matches your application's part number.
