Code P0326 MINI Description

The Knock Sensor (KS) senses engine knocking (also known as detonation or pinging) using a piezoelectric element. The sensor is attached to the cylinder block, cylinder head or intake manifold. A knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the Engine Control Module (ECM). The ECM uses this signal to retard the ignition timing and protect the engine from this damaging pre-ignition.
