    DTC P2111 - throttle valve drive error

    I have just wheeled the old dear out of the garage after three months of inactivity due to me having a knee operation. She has been connected to an optimate for this period so the battery is fine, but there are a number of DTC codes: P1574 Cruise Control Issue due to other problem; P1135 Traction Control issue due to ABS problem; P2111 Throttle Valve Drive Error.

    Short of getting her recovered to the Stealer, does anyone have any advice on the above, particularly the Throttle Valve Drive Error, which is probably what is preventing her from starting?

    that's odd, maybe a rodent chewed up wiring?

    Seriously, the first thing I would try is to disconnect the battery for 30 minutes or so and reconnect.  sometimes works miracles...  Beyond that depends on how willing you are to remove the lady's skirts and dig deeper...

    Shaun, did she start ok? Even with a battery charger if the battery is done its done. When I had battery issues I had all sorts of errors showing up but they were all linked to low voltage. You should put a volt meter across the battery to see if its ok.

    that is true, I had a BMW R1150RT that would throw codes and actually disable the ABS when cold starting with a battery that was getting old.  You really need to have the battery load tested at a battery store, as a battery that shows ok volts doesn't necessarily provide enough current for the bike to start/run properly.

    My KLR will turn over with a failing battery, but will not start, apparently not enough juice to power the ignition and turn it at the same time.
    Good luck, hope it turns out to be that simple!  I always love a simple solution..

    This is so true,.....I did look at buying such a load tester myself but the range/choice is huge and the cost of course. :033:

    Hmmm, I didnít think of that. She turns over really well, with no signs of slowing down, but she has done 50K miles since I bought her new in 2015 (so nearly 4 years old).
    However, I do get a traction control error as soon as I turn on the ignition (which has been linked to the P2111 code in the past), so I am wondering whether said valve is checked, and maybe even operated through a cycle, during the initial ignition-on period?
    Iím thinking that perhaps it is just a sticking valve due to not being used for 3 months and that it can be freed off? But what is needed to do this? Tank & airbox off? I donít have a workshop manual, but I should be able to get that far...?

    Just to be clear - she doesnít start at all, but does turn over with enthusiasm!

    Hi ShaunDW,

    Just got back from work !

    P2111 - Throttle Valve Drive Error -

    The Service Manual gives a possible cause as a "Return Spring Malfunction".
    I would also interpret that as being a possible stuck Throttle Valve Drive.

    The other DTC's for the Traction Control and Cruise Control could well be spurious
    and/or related to Low Voltage, but they should not prevent the engine from starting,
    so I would concentrate on the Throttle drive first.

    To get at the Throttle Bodies, the Fuel Tank needs to be removed.

    To remove the Fuel Tank, first the Fairings need to come off :

    HOW TO: Remove the Fairings and ......

    Then : HOW TO: Remove Fuel Tank and .....

    There's also a useful article about Balancing the Throttle Bodies,
    which has some Photo's and useful information ....

    HOW TO: Balance Throttle Bodies

    If you are going to attempt this work yourself, I would recommend getting a Service Manual
    ( from any Authorised Triumph Dealer ), and the after market "DealerTool" device -
    which allows a number of Tests and checks to be carried out, and DTC codes to be erased.

    When the Throttle Valve Drive error has been sorted, and the Main Battery confirmed as being in good order,
    then a Reset of the Cruise Control system may sort those other two issues out,
    which can apparently be accomplished with a sequence of button presses as described here :

    Digital MPH and Cruise Control Not Working.

    Cheers  :821:

    Thanks for all the above Coconut, I hope to attempt all this tomorrow.
    Failing that, Iíve got a 50K service booked for next Friday, including collection.
