Hitachi Automotive Ignition Knock (Detonation) Sensor KNS0004

Ignition Knock (Detonation) Sensor. (KNS0004) by Hitachi Automotive

As part of an engine's protective network, Hitachi's knock sensors are designed to work in harmony with the engine control module and other sensors to ensure your vehicle runs optimally. Highly sensitive and accurate piezoelectric crystals convert vibrations generated by the engine into electrical signals. The ECM then uses these signals to decide whether adjustments are needed to the ignition timing and other operating characteristics to reduce engine knock and possible engine damage. Designed to meet the exact needs of each specific vehicle, Hitachi knock sensors are the premium choice.
