When the check engine light comes in on the 2009 Toyota Prius it means that there was a problem detected with the vehicle. It can mean a broad range of things from something simple like a loose gas cap or something more serious and more costly. If the light is blinking You should park it and not drive it any longer until the issue is resolved. To figure out what is wrong with the vehicle You can either try fixing stuff, see if it goes off by itself or plugging in a scanner and seeing which code(s) pops up. Sometimes the light will just go away by itseLFAfter being driven for a while. You can also see if the problem is with the gas cap by trying to tighten it and seeing if that resolves it.

If the check engine light on the 2009 toyota prius has come on it can mean many different things. It can be something minor like a loose gas cap or a reminder to get the vehicle serviced. It could also be a major issues like engine misfires, low oil pressure, ect. Generally if there is any problem on the car and the ecu detects it then the light will come on. When it does you can take it and have it scanned with an obd scanner and find out what the specific issue is.
