This DELPHI Detonation Sensor (part code AS10201) is engineered to accurately detect engine knock or detonation. Upon detection, it sends a signal to the Engine Control Unit (ECU), allowing it to adjust ignition timing and fuel mixture. This process is crucial for preventing engine damage caused by uncontrolled combustion and for maintaining optimal engine performance and fuel efficiency. Manufactured by DELPHI, a trusted name in automotive components, this sensor ensures reliable operation and longevity.
