Hey curious before I take my car to AutoZone but my check engine light came on and was wondering if the 2008 civic si sedan has a ECU fuse as I looked in the manual and did not see it, would it be the F1 Main fuse to reset the light? Trying to see if it is just a faulty light before I take it in as I literally bought the damn thing from a dealer just last week.

 

Have the dealer correct it.

 

The vehicle stores various specific data in non-volatile memory even if there is no electrical power such as when the battery negative terminal or some fuses are disconnected. Only some system stored data is lost when the battery or some fuses are disconnected. It is not like older Hondas.

An OBD-II compatible scan tool can reset error (trouble) code(s) depending on the type of trouble code and the scan tool.

Even with the code(s) reset, the error messages will continue to show up if the problem/fault still exist or is detected. Some faults take more than one or more trips and/or conditions for them to trigger the Malfunction Indicator Lamp (aka Check Engine Light).

For some issues, if the problem gets corrected, the Check Engine Light go off on its own.
