ECUs, PCMs, and ECMs rely on sensors that monitor various parameters such as engine temperature, air intake, throttle position, and more. Based on the data collected from these sensors, the control modules adjust fuel delivery, ignition timing, and other parameters to optimize engine performance and efficiency. PCM (Powertrain Control Module) The PCM, or Powertrain Control Module, is an integrated control unit that oversees the engine, transmission, and other components of the powertrain sy...

The Engine Control Module (ECM) is another term used interchangeably with the ECU or PCM, depending on the vehicle manufacturer. It performs similar functions in monitoring and regulating engine performance but may have slight variations in design and features. The ECM is another term for the ECU but is often used interchangeably. It focuses specifically on controlling the engine's operation, including fuel injection, ignition timing, and emissions control to ensure proper functioning and eff...
