2008 Toyota Prius OBD Codes

hmm...I had something similar to this happen to me when I had my 06 Highlander Hybrid during a trip. I knew what it was though (got bad fuel from a small town). I will suggest first to see if it may the same issue. Try running some fuel system cleaner through it such as Seafoam (may take a few tanks of fuel till it stops throwing codes completely). Have you changed the plugs recently or at all? These system are more sensitive than a conventional car when it is watching timing. try the fuel system cleaner and see if it clears up (may have to keep resetting codes). Do the codes come back right away, or does it take a while? Check air filter as well and replace if old and dirty.

Hello, Johnny

Thanks for the reply and the suggestions. Yea I did not change the plugs and don't remember the last time they were changed, if they even where changed. And the codes did not come back right away I think they came back around couple of days.

Ok, I would get the plugs changed cause they are due if they have never been done. Get some Seafoam or Lucas fuel cleaner run it with a full tank and see how that goes. I was having the same problem.
