What is the reason for the trouble light of Honda's new Civic engine?

Hello friend, if the engine fault light is on, you should go to the repair shop first, ask the master to use that special car maintenance computer to detect the fault code for you, and then troubleshoot it according to the meaning of the fault code. I can tell you for sure that the fault light is on because of the performance failure of the electronic components in the electronic fuel injection system of that engine. I hope my answer can help you. Please feel free to contact me if you have any questions.
