Bosch 0 261 231 146 knock sensor

A knock sensor, also called a detonation sensor, is a component mounted on the engine block that detects uncontrolled knocking combustion of the fuel-air mixture. The signal from the sensor goes to the engine control unit, which uses it to adjust the ignition timing angle, protecting the engine from damage caused by knocking combustion.

Use

This Bosch sensor, marked with catalog number 0261231146, is a replacement part fitted to many passenger car models, including several popular Volkswagen Group models. Before buying, it is worth comparing the catalog number with the number of the sensor currently installed in the vehicle, because different engine versions of the same model may require a different sensor.

Symptoms of a faulty knock sensor

• Loss of engine power and worse driving performance.
• Increased fuel consumption.
• A characteristic knocking or pinging in the engine under load.
• The check engine light coming on.
