Mitsubishi Knock Sensor

Description

Knock sensors are devices used in internal combustion engines to detect engine knock or detonation, a metallic knocking or pinging sound caused by premature combustion. These sensors help protect the engine from damage and maintain its performance, efficiency, and lifespan by sending a signal to the engine control module (ECM) to adjust the ignition timing and prevent further engine knock. Knock sensors are essential in modern engines as they help to protect the engine from damage, optimize its performance, and reduce emissions. They also help increase the engine’s lifespan and improve fuel economy.

When a knock sensor is faulty, it can cause reduced engine performance, reduced fuel efficiency, Check Engine Light illumination, and difficulty starting the engine, among other symptoms. It is vital to have a proper diagnosis and repair done to prevent further engine damage and to ensure that the engine is running optimally.
