While PCM, ECM, and ECU are often used interchangeably, there are subtle differences between them. The Powertrain Control Module (PCM) typically controls both the engine and transmission, while the Engine Control Module (ECM) focuses solely on the engine. Faulty Sensors: Sensor malfunctions can cause inaccurate data to reach the ECU, leading to performance issues. Wiring Problems: Poor connections or damaged wiring can disrupt communication with the ECU. Software Glitches: Software bugs o...
