The engine control module refers to a specific part of the car’s electronic system. Its primary function is to determine whether a signal from a sensor is significant enough to need further attention. The engine control unit then generates an output signal accordingly. What makes it unique among other circuits is that it has fewer or no external ports or connectors.
