Our expert insights into knock sensor replacement in Liverpool

Our expert insights into knock sensor replacement in Liverpool

What does a knock sensor do?

The knock sensor is bolted directly onto the outside of the engine block and is used to detect vibrations and detonation “knock” noises from the engine to prevent engine damage.

What are the symptoms of a bad knock sensor?

Below are the top three symptoms that could indicate you need to replace your knock sensor:

  • Engine pre-detonation known as “pinking” or knocking
  • Reduced engine power
  • Increased fuel consumption

What happens when we do a knock sensor replacement on your car?

Our certified mechanics will:

  • Perform a diagnostic check to discover any fault codes coming from the knock sensor and other related parts of the engine.
  • Once they confirm that the knock sensor is faulty, they will fit a replacement knock sensor.
  • Once replaced, the mechanic will start the engine and recheck for fault codes.
