    I just did the 15 000km service on my 07' 990 Adventure.
    But now when I'm in neutral, my FI light gives me the following error code:
    FI blinks 4x long, 5x short, pause.

    The owner's manual tells me that error #45 is
    Signal / component: Lambda probe heater for rear cylinder
    Error description: Short circuit to ground / positive

    Is that something I can fix myself, or should I head straight to a KTM workshop?

    Thanks for your help.

    you may have gotten a wire pinched during reassembly. I had a FI code come up too, and mine was loose connector. Don't worry though, the greatness of CPModem will shed some light on this. He even provided pictures on my particular problem. Good luck!

    Go trace the wire from the sensor up and see if you can find the issue. It is some kinda ground issue.........

    Thanks guys.
    My post was a little misleading as I didn't service the bike myself. A KTM workshop did. But I'll try to trace the problem.

    IMO take the bike back and make them repair the problem... aftertall you paid for the service, right?

    It's real easy to get the rear lambda probe wire pinched in the left side crash bar clamp (if you have one). Or so it has been reported.:nod

    I stripped the left tanks on Saturday, and the cable is not obstructed or pinched by anything.
    The error message keeps on coming up.

    I think I'll drop the bike to a KTM workshop...
    Unless I'm missing something.

    If the wiring checks out, sounds like it did, it is very possible the Lambda sensor is bad. At the very least, now you have some knowlwdge so the 'stealer, will have a harder time trying to B.S. you.

    Did you do a continuity check onthe wires to make sure there isn't a short somewhere? Sometimes the short is not always caused by a pinch. SOmetimes if the wire has been pulled is can cause the wiore to come out of connectors and such and cause a short.

    I'll check again thanks.

    My KTM workshop says that they never saw a faulty lambda sensor before...

    2 questions:
    Does anyone know if the 2 year warranty covers faulty lambda sensors?
    Should I really be bothered by a faulty lambda sensor? In other words, can I ride without it?

    When the ECU senses a bad sensor it changes from closed loop mode and enables a preset map. Performance and fuel mileage will suffer as the FI will no longer adjust to engine and ambient atmosphere conditions. The Lambda sensor should be covered under the warranty. Your KTM workshop should have told you that when they said that they haven't ever seen a faulty lambda sensor.
    Just sayin'

    Thanks again cpmodem!
    My KTM workshop doesn't even know if the lambda sensor is covered under the warranty!:bluduh

    That's BS - big time
    Happened to me. Clamped rear sensor wire on left crashbar and caused the earth short.
    It's possible they clamped the wire, noticed the error and removed the crashbar to rectify and never reset the error code
    Your bike has a 2 year warranty - get the sensor replaced !!

    Did shorting the wire cause an ignition fuse to blow or just a code?

    I just did what cpmodem pointed out: clamped the cable while reassembling the crash bars. TuneECU reported it and here are some pics that might help others

    I had an issue with a cylinder temp probe that turned out to be an intermittent short due to a wire rubbing on a machined bit of the engine case. It took a LOT of time and light to find it. SLOWLY go over your wire with plenty of light bending it a bit.
