Hi all. I’m having a few running issues with the MST. It’s a 1200S Touring 2013. I took the exhaust flap off, an cut the cable, intending to remove the servo. I ran it for a while but it didn’t run well so I put a Heal Tech exhaust valve eliminator on it. Made no difference at all (didn’t activate an engine warning light). It then started to act really strangely, stalling when warm and lack of throttle response. I’m just waiting on a licence from Melcodiag but, in the meantime, I just wondered if I should not have run the bike without the eliminator on, or, could it be a duff eliminator?
Didn't run well could mean any number of things. In terms of the Eliminator, personally I'd go for one of the physical options, like a spring or wotever .
Finally got Melcodiag working. Several errors about the exhaust valve being disconnected - P1009 Status 28, P1007 status 68, P100B status 28, with a few others relating to MAP sensors I think. Does anyone know if this means that the Servo Buddy is rogue?
Clear the errors, run the bike and see what errors then show. Apart from showing an error a disconnected exhaust valve will have no effect on the running of the bike, as long as the valve is open. A dodgy MAP sensor on the other hand certainly will.
ir Thanks Derek. I was under the impression that the servo eliminator, if not plugged in, would make the bike run roughly but I have taken the flap off so open all of the time which makes sense. Errors showing are: P0105 - Manifold absolute Pressure/Barometric Pressure Horizontal Circuit malfunction. P0110 - Air Intake Temperature Circuit Malfunction. P0030 - H02S heater Control Circuit (Bank 1 Sensor 1) Do you know the fix for these? I got a couple of MAP sensors off Amazon and have tried them on the Horizontal cylinder (easier to get to) but make no difference to the running, although only static with the engine running.
Not really. The MAP sensor error would indicate a faulty MAP sensor but if replacement makes no difference then it could be the other faults. The air temperature sensor is mounted in the nose cone. You have to unplug it when removing the nose cone. Are you sure it's connected? P0030 I believe refers to the heater circuit for one of the Lambda sensors.
The MAP sensors I got from Amazon were quite cheap non OEN. £58 for 2 sensors. I’m sure you know that they are quite a bit more than that normally so I’m thinking they may be duff! Or not compatible with the bike even though they stated they are a replacement for the original part number. I’ll check the nose when I get back as that is probably not connected.
Yes, I've heard varying reports about MAP sensors from Amazon. Some saying they worked fine others saying they were no good. It may depend on the seller.
Well, nose cone sensor plugged in. Unplug it I get an EML. tested the vertical map sensor (pig to get at!) with the old sensor that I thought was malfunctioning and when i unplug it, the revs change and engine stops. Plug it in and start the bike again, fine. Unplug the horizontal MAP sensor and nothing at all happens, no increase or decrease in revs whatever sensor I try
Just to be clear are those active errors or memorised errors? Does MelcoDiag differentiate? P0105 is horizontal cylinder MAP and P0106 is vertical cylinder MAP. These MAP sensors from Amazon work and are identical to the OEM ones Germban 55241571A Air Pressure Sensor For Multistrada 1200 ducati Panigale 2012-2017 Diavel 1199 r14 Engine MOtor https://amzn.eu/d/0RNAFCm
Thanks very much for that. Sent the others back and followed your link so, fingers crossed, that should do it. Funny but I spoke to someone in a Ducati dealership who told me that the ones they sell are just over priced
Usually I replace the pair. For the extra cost of the 2nd MAP sensor compared to the time and effort involved in getting to them, it’s worth doing them both. You can bet your bottom dollar that if one has failed the other is not far behind.
They’re certainly not made by Ducati but are bought in. However, Ducati will be doing random sample tests on each delivery to ensure they’re up to spec. Most items like this are made in China these days but, as we all know there are varying degrees of quality in Chinese manufacturing.
