The engine control module (ECM), also known as the powertrain control module (PCM) or engine control unit (ECU), is a crucial component in modern vehicles.
It plays a key role in controlling the various functions of the engine, ensuring optimal performance, efficiency, and emissions compliance. In this blog post, we will delve into the inner workings of the engine control module, discussing its functions, components, and importance in vehicle operation.
The engine control module is essentially the brain of the vehicle's engine system. It receives input from various sensors throughout the vehicle, such as the oxygen sensor, throttle position sensor, and crankshaft position sensor, and uses this information to regulate key engine functions, such as fuel injection timing, spark timing, and air-fuel mixture ratios. By constantly monitoring and adjusting these parameters, the ECM ensures that the engine operates smoothly and efficiently under a...
