Hi guys,

My FP3 keeps throwing up a Crank Position Sensor issue. It clears and resets but it's becoming a pain in the proverbial!

Has anyone ever changed this? I have had a quick look and it would seem that the engine has to be separated to get to it! Can't see this being the only way to replace such a small part that is likely to need replacing at sometime.

Thanks in advance.

Is it only the FP3 or is the bikes ECM also throwing the code?

Well, after many hours of messing about and despite the error code stating that the crank sensor had failed it would appear that the issue was created by moisture entering the engine kill switch. If anyone else gets an issue with this before spending £££'s and hours dismantling things just take apart the throttle handlebar control and completely drown it with WD40 - the result is that the bike runs 100% now and the kill swich no longer causes an issue!!!

Good tip. Another one is to learn from the mistakes, or at least the hard work of others. Your post reminds me of similar problems another member posted about but couldn't solve. I'll point him to this thread.

Hi, Old Git. Before I go taking apart my component do you have any advice maybe even a how to vid somewhere of what exactly you did? My fear is that it just plops off the handlebar, and I can't get it back together. Also, I am concerned it might be real intricate in there or I overspray everything.

Hi
Well there is only a couple of screws located at the bottom of the handlebar mount. Once these are removed the component just splits open - nothing falls out as the actual switch and the throttle cables need more dismantling before you can remove them and refitting is simply a case of retightening the screws. In reality this should be removed when you service the bike anyway so that the throttle cables can be lubricated so may be a good thing to do with some decent oil at the same time?
There is nothing intrecate in there at all, just a switch and the throttle cables / pulleys.

With regards to overspraying - with WD40 THAT IS SIMPLY NOT AN ISSUE.
WD40 expells moisture and as such does not cause short circuits or damage to any electrical components - just spray everything with as much as you can.

I spray WD40 all over my bike - it brings up the plastic brilliantly and makes the black engine look new. I also spray it on wheels and hoses, in fact everywhere except the brake discs / pads and the result is that my bike is 3 years old yet looks brand new!

Hope no-one else has the crank issue but it's worth remembering ;)
