Pressure Sensor!

The Air Mass Sensor is a known weakness on the earlier bikes. There are 2 fitted in the air box and it's a pain in the arse to change them as you have to remove the petrol tank to get at the air box. Andy

 

Yep, that's about right. Andy

 

It was done during a major service so no biggy. However, I have recently removed the petrol tank on more than one occasion and it’s a llloooonnggg job. Even knowing what I was doing, I’d say 5 to 6 hours, start to finish. Doable but a real pain. Both the air grills, both the metal side panels, both the infill panels and the lower dash need to be removed before you can get the fuel tank cover off. The tank has 2 bolts at the front which when removed, allows the tank to pivot up from the seat end which exposes the 2 quick release fuel connections and the electric plug for the pump and fuel sender which need to be disconnected before the tank can be removed. That then allows you access to the air box. The 2 sensors take a couple if minutes to change. Can’t remember the cost if the sensors but not pounds cheap, more tens of pounds expensive. Andy

£75 each from Ducati, easy job once the tank is out of the way!

I had the same issue with an intermittent red pressure sensor warning on my ride out a week ago on my Diavel. Bike ran rougher below 4k and backfired a bit more than usual. Diagnosed one open circuit air pressure sensor and other one playing up. Changed both sensors (£164 for both delivered).
The bike was never the smoothest before the fault code on the dash showed up but it is now so much smoother at below 4k. Guessing that one of the sensors was not working fully before the light came on last week.

 

Sensors are about 80 quid if I remember rightly ... had mine done at Pro Twins
