As above, I'm having a recurring code 12 fault & need to replace the CPS...
What is the OEM part #?
All replies greatly appreciated
Seems to be: 5YU–81670–00, Pick-up assy.
I've ordered one for mine too has all the tell tales signs of failing.
£93 inc post from MPS (A J Sutton)
Not with me yet though
Ordered my sensor a week ago from cmsnl.com, €103 including P&P, 2 weeks before they can ship, part not in stock
Finally arrive and fitted, bike the same so it wasn't the problem

I think I've found the problem (famous last words:))
When I took off the Idle control valve I linked the two cylinders together (pipe intake to intake) I think may have upset things as there are cylinder pressure sensors? unlinked and intake stub now blocked, I took her test ride she seamed better eliminating the spluttering at lower revs.
