ELECTRONIC CONTROL UNIT
What does the ECU do?
The ECU is responsible for monitoring all aspects of engine operation, making adjustments based on driver input, and more. It reads the amount of airflow entering the engine to adjust the throttle and it controls the Check Engine Light (at least partially). It also manages ignition timing, idle speed, variable valve timing, electronic valve control and more. Information is sent to the ECU from sensors located throughout the engine bay that do everything from measuring coolant temperature to camshaft position. In short, the ECU has a huge impact on your vehicle’s operation, including everything from the available power to emissions control. Enjoy the video for more details informations.
Thank you.
