The engine control module (ECM), also known as the powertrain control module (PCM) or engine control unit (ECU), is a vital component in modern vehicles.
It serves as the brain of the vehicle's engine, controlling various functions and ensuring optimal performance and efficiency. In this blog post, we will delve into the details of the engine control module, discussing its functions, importance, and how it works.
Functions of the Engine Control Module
The engine control module is responsible for overseeing and controlling a multitude of functions within the vehicle's engine system. Some of the key functions of the ECM include:
1. Fuel Injection: The ECM controls the amount of fuel injected into the engine cylinders based on factors such as engine speed, load, and temperature. This helps to optimize fuel efficiency and performance.
2. Ignition Timing: The ECM controls the timing of the spark plugs, ensuring that the combustion proc...
