An engine control module (ECM), also known as a powertrain control module (PCM) or engine control unit (ECU), is a critical component in a vehicle’s overall performance.
It serves as the brain of the vehicle, controlling and regulating various engine functions to ensure optimal performance, efficiency, and emissions control. In this post, we will delve into the workings of an engine control module and discuss its importance in modern vehicles.
The engine control module is essentially a small computer that is responsible for managing the different systems in a vehicle's engine. It collects data from various sensors located throughout the engine and makes real-time adjustments to factors such as fuel injection, ignition timing, throttle position, and exhaust emissions. This ensures that the engine runs smoothly, efficiently, and in compliance with environmental regulations.
One of the key functions of the engine control module is to monitor the engine'...
