Product Details
Ignition Knock Detonation Sensor by Holstein®. OE Replacement Parts You Can Trust. The Knock Sensor is able to detect mechanical stress and produces a voltage when the car knocks or pings. Under heavy acceleration, it sends signals to the ECU and the ECU retards the ignition timing to compensate for the knocking, which in effect protects the pistons and rings from damage. Knocking also occurs when using lowgrade fuel and having the knock sensor allows you to use different grade fuels without causing engine damage.
