The ABAKUS Detonation Sensor (part code 120-09-053) is engineered to accurately identify engine knock or detonation. This critical sensor monitors vibrations within the engine block, signaling the engine control unit (ECU) when abnormal combustion occurs. By detecting detonation, the ECU can adjust ignition timing in real-time, retarding it to prevent potential engine damage. This proactive measure helps maintain optimal engine performance, prevent pre-ignition, and contribute to better fuel economy. This sensor is designed for reliable performance and durability, ensuring consistent and accurate readings under various operating conditions. Its direct fit design simplifies installation, making it a straightforward replacement for your vehicle's original component.
