I've got a 2015 Prius 3 and the check engine light came on today. It's giving me P0445 and P0441 codes. The internet says it has something to do with the evap system. Anyone know what it can be? My Prius has just a little over 36,000 ,lies but I have the extended warranty. I have an appointment at the dealer tomorrow.
JC is right. However, the code indicates a major leak that may require you to clear the code to make the light go out. Just be prepared in case the light doesn't go off after a few miles. This code is usually caused by the fuel cap being cocked in the fill neck as opposed to just being loose. In either case, it should be very evident when you check it.
