What is an ECM? The Engine Control Module (ECM) is similar to the ECU but may be used interchangeably in some vehicles. It is responsible for monitoring and regulating engine functions to maintain peak performance and efficiency. The ECU receives input from various sensors in the vehicle, such as the oxygen sensor, throttle position sensor, and mass airflow sensor. Based on this input, the ECU makes real-time adjustments to the engine's operation to optimize performance and fuel efficiency....
