HELLA 6PG 013 114 851 Knock Sensor

Piezoelectric sensor HELLA Knock sensors use a piezo element to detect the combustion in each cylinder and send data to the ECU that adjusts the ignition timing to prevent engine knocking. Contributes to higher engine performance and optimized fuel combustion and reduces unwanted engine noise and wear. Faulty sensors can cause check engine light activation, fault codes, loss of power or increased fuel consumption. DESIGNED FOR DURABILITY - Hella sensors are resistant to vibration, dirt and moisture, ensuring long life and reliability.
