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 that helps regulate and monitor the various functions of the engine to ensure optimal performance and efficiency.
This sophisticated electronic control unit is responsible for controlling fuel injection, ignition timing, and other key engine functions. The ECM plays a crucial role in maintaining the balance between performance and fuel efficiency by constantly monitoring and adjusting various parameters such as air-fuel ratio, engine load, and exhaust emissions. It uses sensors to gather data …
