    Engine Management Light

    Sometime last year, the engine management light stayed on after engine start. As the bike was still under warranty, my local Honda dealer took it and diagnosed a faulty front wheel speed sensor, replaced it and I took the bike back.

    A couple of months and a few thousand miles later, the same thing happened, quickly sorted by the dealer by again, replacing the front wheel speed sensor.

    Near the start of the lockdown, I saw that the light was staying on again. This time I insisted that when they re-opened, they did a deeper investigation as I did not want a repeat. I managed to get the bike into the dealer at the start of this week and they have diagnosed the same front wheel speed sensor as the issue but have contacted Honda asking them for further guidance as to potential causes. Honda have replied saying that the next step, following a thorough check of the bike wiring, will be a wiring loom change.

    The bike is a 2018 model with around 10k miles on the clock.

    I've not heard of this issue before on the new model VFR800 but thought I'd let everyone else know just in case someone else experiences the same thing.

    Skids, good morning.
    Just trawling through some older posts. Did you get a final resolution to this issue?

    Yes,  it was the abs sensor, which they've replaced twice.  No recurrence since, yet.

    Glad it's sorted. Must've been a batch fault, a tub full of Friday sensors  :013:

    Sadly this has recurred and the bike is with the dealer who is looking at wiring change. Not sure yet what the extent of the wiring change is and still waiting for them to confirm it's still a warranty claim, which it should be as far as I'm concerned.

    Sorry to hear that Skids 😕
    The only consolation is that we're heading into the least bikeable (new word) season.
    I feel your frustration though. That they can't seem to bottom the fault is bad, that there's even a hint that it might not be covered under warranty is worse 😠
    That said, you have plenty of evidence and several dealer visits for this fault which has occurred repeatedly during the warranty period. It really needs proper investigation not just throwing parts at it till it goes away. Hopefully their best technician has access to the best fault-finding gear and knows how to use them. I'd be concentrating on loom connectors in-line with the sensor, particularly near any point of flex (steering etc).
    They need to get the wheel in the air and keep it spinning whilst simultaneously wiggling the loom. If they can get an oscilloscope on the signal they can watch that?

    They also need to check the gap between the sensor and rotor if possible compare this with another CR. I read once of a bike which started having abs issues after a rear tyre change. The wheel spacers were of slightly different length and had got mixed up during refitting which meant the wheel (and abs rotor) then sat slightly further away from the sensor. As a result the abs signal was occasionally lost due to slight run-out.

    Thanks m8.

    Luckily, the front wheel spacers are the same width......I think!  :003:

    A two year old bike with only 9000 on the clock?  Certainly should be a warranty claim.   :211:

    Amazing how these things can escalate.  There is a Youtube review channel in the States that is having real issues with a new Defender.  After just over 200 miles the engine check light came on, the dealership seemed to fixed it, but broke the cameras in the process, then the check light came back on.  Eventually JLR declared that they could have a new engine, a new Defender or their money back.  They accepted another vehicle - although it was not to the basic off road spec they wanted; so they asked for a winch.  In fitting the winch the dealership cut through a loom that quote "cannot be replaced" thus temporarily at least, writing off that vehicle.  They have a third on order...

    I think they were just checking whether they could claim it was out of warranty, which it is now, but the first iteration of this fault was in-warranty so I don;t think they would have a leg to stand on.

    Anyway, the dealer has ploughed into loom checking and test riding but I haven't heard back from them since yesterday.

    Just a well I don't need the bike.  :015:

    I hope they find something conclusive Skids. Rather than "thinking" they've sorted it. You don't want this going on and on.

    Mine is back at the dealer - but that's for tyres. They agreed with me that there was insufficient tread. I think they're the original tyres (Bridgestone Battlax Adventure). They are fitting me some Sport Touring road tyres. I'm aching to get it back but like you said, can't really use it at the moment anyway.
    Good luck with yours 👍
