    My 2006 Prius has had it's check engine light on for about a year. I've continued to drive it, though!

    Today it failed state emissions inspection with diagnostic trouble codes: P0301, P0441, P0455, P0505. Attached is a screenshot of the report.

    Any idea if these are going to be expensive fixes? I'm trying to decide whether to keep the car or buy a new one.

    Basically, it's talkiyabout your evaporative mission system; misfires on cylinder one, and a speedomer readins has some issues. I don't think they'd be all that expensive. Depends what the reasons are for the misfire on cyl1, vis-à-vis.

    Called a mechanic who said that the codes are possibly related to different issues.. he said it'll be a few hours to diagnose the issues.
