Nissan Maxima Service and Repair Manual: P0327, P0328, P0332, P0333 KS
Description
The knock sensor is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the ECM.
