An engine control unit (ECU) is the main electronic module responsible for managing engine operation. It processes signals from sensors such as RPM, air flow, temperature, pressure, oxygen sensors, and throttle position to control fuel injection, ignition timing, turbo operation, EGR system, and other engine functions.

The ECU is the central “brain” of the vehicle and directly affects engine power, fuel economy, emissions, idle stability, and starting performance. It communicates with transmission, safety, and comfort systems via the vehicle network.

If the ECU fails, symptoms may include engine warning lights, unstable operation, poor starting, loss of power, increased fuel consumption, limp mode activation, or diagnostic communication issues.
