    We are driving near Dallas.

    Torrential downpour and big shallow flooding (3-6 inches.)
    Made it through, no issues.
    Stopped for lunch.
    On restarting, I have a permanent P0607... And 4 hours of driving left today.

    I assume something got wet. For now I intend to keep going.

    Is it dangerous or harmful to drive with this DTC?

    By that, do you mean it is shown only as a permanent code, and not as a current code? Is the check-engine light now on?

    If it's only a permanent code, I'd assume that something got wet, and is not now. Maybe worth checking the heated oxygen sensor wiring when convenient, see if there's a reason its water-resistance might be less than designed, or a way to improve it.

    What inspired you to scan for codes after lunch?

    Pretty sure he had a check engine light on restart after lunch.

    Maybe try this thread: Well.... my annual P0607 is back (Calling the Gurus) | PriusChat

    Thanks...
    It is historical and current. Doesn't clear. Check engine light-inspired...

    Continuing south. Maybe sunshine in Waco?
