The ECM, or Engine Control Module, is similar to the ECU in that it manages engine functions but is typically used in older vehicle models. It controls ignition timing, fuel injection, and emissions systems to keep the engine running smoothly. The ECU is responsible for managing the engine's performance, fuel injection, ignition timing, and emissions control. It collects data from sensors throughout the vehicle and adjusts settings to optimize engine efficiency. Common issues with the ECU...
