ECU (Engine Control Unit): This is the brain of your car's engine management system, controlling various functions such as fuel injection, ignition timing, and emissions. PCM (Powertrain Control Module): A more advanced version of the ECU, the PCM oversees not only the engine but also the transmission, ensuring optimal performance of the powertrain. ECM (Engine Control Module): Similar to the ECU, the ECM focuses on engine-related functions, monitoring sensors and adjusting settings to maint...

The ECM is similar to the ECU but primarily focuses on managing engine functions. It communicates with sensors to regulate fuel delivery, air intake, and exhaust emissions to optimize engine performance. Check for error codes using a diagnostic tool to pinpoint the problem accurately. Inspect wiring and connections for any signs of damage or corrosion. Update software and firmware to ensure optimal performance and compatibility. ...
