Modern vehicles are equipped with sophisticated electronic systems that help regulate and control various aspects of the engine’s performance.
One of the most important components in this system is the engine control module (ECM), also known as the powertrain control module (PCM) or engine control unit (ECU). The ECM is essentially the brain of the vehicle, responsible for managing and monitoring numerous functions to ensure optimal performance, fuel efficiency, and emissions control. In this blog post, we will delve into the workings of the ECM and its crucial role in the overall operation of a vehicle.
The engine control module is a small computer that is typically located in the engine bay or underneath the dashboard. It is connected to various sensors throughout the vehicle, such as the mass air flow sensor, throttle position sensor, oxygen sensors, and more. These sensors provide real-time data to the ECM, allowing it to ...
