    Exclamation Fault DTC-8901: UEGO Microprocessor Internal Fault

    Hey everyone! Just picked up my 2017 Moomba Helix this spring and am loving it so far. We live in Spokane, WA and have a place up at a Priest Lake in Idaho and the boat lives up there. I did the engine diagnostic and I am getting DTC 8901: Microprocessor Internal Fault. Looked in these forums and all over the internet and can’t find a thing. Called the dealer and they told me they’ve never heard of this code and if it’s not affecting performance, which it’s not, then I shouldn’t worry about it. Just want to make sure this will not cause long term issues. Anyone able to help me out with this or give me some troubleshooting steps?

    Does it come up anywhere on the screen, or was this only something that shows using g a diagnostic tool?

    Can you clear it? If so, does it come back?

    It shows up on the screen. When I turn my battery off, it clears, but when I check for faults again, it comes back. IMG_2205.jpg
