Piezoelectric Sensor Corresponds to the original part in colour: black HELLA knock sensors use a piezo element to detect combustion in each cylinder and send data to the ECU, which adjusts ignition timing to prevent engine knock. Contributes to higher engine power and optimized fuel combustion, reducing unwanted engine noise and wear. Faulty sensors may cause a check engine light, error codes, power loss, or increased fuel use.
