The DELPHI Detonation Sensor (AS10238) is engineered to accurately detect engine knock or pinging. This critical component monitors vibrations within the engine block and sends signals to the engine control unit (ECU). The ECU then adjusts ignition timing to prevent detonation, safeguarding the engine from potential damage and ensuring optimal power output and fuel economy. Designed for reliable performance and durability, this sensor is a direct fit for compatible vehicle applications.
