The ECU is responsible for managing the engine's functions, such as fuel injection, emissions, and ignition timing. It collects data from sensors throughout the vehicle and adjusts settings to optimize performance and efficiency. Understanding the role of this crucial component and how it relates to the powertrain control module (PCM) can help you diagnose and resolve problems quickly and effectively. In this comprehensive guide, we will break down the differences between ECM, PCM, and other ...
