    Can anyone help please? My 08 Prius check engine light was intermittent but now on all the time- car runs great. Went for state inspection and they gave me codes p1116 and p1120. Failed inspection.

    Thank you for this information. I am taking my Prius to a hybrid mechanic. My car failed NJ inspection because of the check engine light. It runs without issues and the AC is great. Will this be an expensive repair? Just seeking more info from owners who's car threw these codes.
    TIA

    If the mechanic is sourcing "used" OEM parts, the total should be under 1k.
