The DELPHI AS10240 Detonation Sensor is engineered to precisely identify abnormal combustion events, commonly known as engine knock or pinging. By accurately sensing these vibrations, the sensor provides critical data to the engine control unit (ECU). This feedback allows the ECU to make real-time adjustments to ignition timing and fuel mixture. These adjustments are crucial for preventing engine damage caused by detonation and for maintaining optimal engine performance and fuel efficiency. A functioning detonation sensor is a key component in modern engine management systems. DELPHI is a trusted name in automotive components, known for producing high-quality parts that meet or exceed original equipment specifications. The AS10240 is built to the same rigorous standards, ensuring reliable operation and longevity. Installation of this sensor will help restore your vehicle's performance and protect its engine.
