    Does anyone know if a fuel pedal position sensor can go bad without throwing a code ? 06 f350 / 6.0

    When it comes to electronics, anything is possible.
    What's the issue?

    rpm's will drop momentarily while driving down the road.if I keep steady pedal pressure trying to keep same rpm it will drop to an idle speed & then pick back up again. It will do this in park also, trying to keep steady rpm it will drop & then pick up again.but I see no codes that are associated.I have pulled egr & cleaned.It didn't look clogged.And I also cleaned tube leading to EBP sensor.

    Easy test, what happens if you are driving with cruise on?

    Well.......I ran down the road with no rpm drops & cruise worked fine . An hour later I ran down the road again & it was acting up with rpm drops & cruise would not come on.

    If it acts up with cruise on, I would say the pedal isn't the problem.
    Do you have a way to watch live data?
