About Engine Control Module

The engine control module (ECM) is an electronic device that operates the engine. The ECM is in charge of the operation of numerous engine parts based on the data that it receives from the sensors in the engine and exhaust system.

ECM Workings

Modern engines utilize some form of fuel injection to transport fuel to the cylinder. The engine control module called the Engine control unit (ECU) regulates the amount of fuel inserted based on the sensor readings. Sensors like the oxygen sensor tell the ECU whether the engine is running rich or lean. The ECU controls a lot including the engine system's idle speed and the time in the engine cycle when the valves open.

Modern design

Newer ECUs utilize a microprocessor that can operate the inputs from the engine sensors. The electronic control module controls the hardware as well as the software. They also include features like cruise control, transmission control, and anti-skid brake control.

Common issues with a faulty engine control module

A faulty engine control module can lead to an engine misfire, poor fuel economy, and a decline in engine performance.
