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...
