Modern vehicles are equipped with a variety of electronic components that help control and monitor the engine for optimal performance.
One of the most important of these components is the engine control module (ECM), also known as the powertrain control module or engine control unit. The ECM is essentially the brain of the vehicle, responsible for managing fuel injection, ignition timing, emissions controls, and more.
The ECM is a small computer that is typically located in the engine compartment or under the dashboard. It constantly receives input from sensors throughout the vehicle, such as those measuring engine speed, temperature, and air intake, and uses this information to make adjustments to the engine in real-time. This allows the vehicle to run smoothly, efficiently, and with minimal emissions.
One of the key functions of the ECM is to control the fuel injection system. By monitoring engine speed and load, ...
