The DELPHI AS10189 Detonation Sensor is engineered to accurately identify engine knock or detonation. This critical component plays a vital role in maintaining engine health and performance by alerting the engine control unit (ECU) to abnormal combustion events. Upon detecting detonation, the sensor sends a signal to the ECU, which can then adjust ignition timing and fuel mixture to prevent engine damage. This ensures the engine operates efficiently and reliably under various driving conditions. Crafted with high-quality materials, the AS10189 is built for durability and long-lasting performance. Its precise design guarantees accurate readings, contributing to smoother engine operation and potentially improved fuel economy.
