Posted: 13:14 - 31 Aug 2021 Post subject: MAP sensor failure - causes? |
|
|
On Friday I went for an annual mini-tour with a few friends, total of around 600 miles. It involved riding to a central meeting location where we stay for the weekend with a Saturday ride-out. Anyway, part-way into the outbound journey the FI light came on - the bike was still running so I kept going and found a safe place to pull over.
Once I had stopped and put it into neutral the FI light blinked its error code to me - code 9. This translates as "Manifold absolute pressure sensor cylinder 1 - input too high/low". Since the engine was still running I kept on going and completed the weekend with few issues - on first starting it would run a bit rough and occasionally stall until the ECU realised the sensor had failed and, I assume, defaulted to a fixed pressure value, after which it would run OK, if a little 'off'.
Anyway, this same sensor failed around 18 months ago and I replaced it with a genuine new KTM one. My question is, could there be an underlying cause of the sensor failing? Spiky voltage? Vibration (it is fixed on a rubber-damped mount)? Or is it just bad luck and/or poor quality parts?
There appears to be a global shortage of this particular sensor; as I was riding the rest of the way to the meet my wife phoned every KTM dealer in a 100 mile radius of my route to see if anyone had one - no luck and some saying back-ordered until November. I have found some used ones on eBay which I will try, pending the arrival of a new one from a KTM supplier. The good point (if there is one) is that I can change it in 30 seconds with no tools (which prompted me to wonder if I could swap it with any other LC8-engined KTMs or Husqvarnas I came across during the weekend... ). ____________________
