Knock sensors prevent pre-ignition in an engine by noticing irregular vibrations and telling the ECU to delay ignition timing. This highly important sensor is usually mounted on an engine block, cylinder head, or intake manifold and contains a crystal which produces a small electrical current when shaken. The sensor is calibrated to the normal engine vibrations and detects engine knock by sensing an increase or decrease in this current outside its safe parameters.

The crystal contained within a knock sensor is a delicate object and as such can be damaged fairly easily. Damage often occurs during front impact crashes or simply from rough handling when working on the engine itself. The symptoms of a faulty knock sensor show themselves when a vehicle’s engine is under load and include poor fuel mileage and a lack of acceleration when travelling at highway speeds. Fuelmiser makes a range of knock sensors that are precise and durable.
