Product Description

The Arrowhead SENSOR KNOCK 3PIN is designed to detect engine knock or pinging in modern vehicles, helping to protect your engine from potential damage. This knock sensor features a round sensor body with a metal insert and an integrated wiring harness, equipped with a brown 3-pin rectangular connector for secure and reliable connection. It plays a crucial role in monitoring engine vibrations and sending signals to your vehicle’s ECU to optimise ignition timing.

This knock sensor is suitable for select Audi, Seat, and Volkswagen models. It is commonly used in vehicles such as the VW Golf, Jetta, Polo, Audi A1, A3, S3, TT, and various Seat models with 2.0 TFSI engines. Please confirm your vehicle’s model, year, engine size, and engine code to ensure correct fitment before ordering.

Common symptoms of a faulty knock sensor include engine warning lights, reduced engine performance, poor fuel economy, rough idling, and unusual engine noises. You may also notice increased exhaust emissions or your vehicle entering limp mode. Addressing these symptoms early can prevent further engine issues.

Replace your knock sensor if you experience any of the above symptoms or if diagnostics indicate a sensor fault. Timely replacement helps restore proper engine operation and prevents potential damage caused by uncontrolled knocking or detonation.
