Hi Chaps - my 2006 machine has developed a fault which is very suspect of a faulty TPS unit. This all started on Tuesday. Was 3/4's of the way to work, filtering through usual London traffic, and i lost all 'drive' - the engine RPM's went from 1450 to 900, 750, 500/450 and 0...
This has never happen before to me since owning the bike. I did notice that the bike was not revving properly as I was getting closer to work, and I could not control the throttle properly at low RPM/speed
Slowing down was also a challenge, as it kept on sputtering... I lost all drive and finally if i didn't keep the RPM's high, it would just cut out. I managed to get to work after about 15 restarts - luckily the other bikers behind us were cool as I think they knew I had issues The ride home was fine, however the next day it started to cut out again.
I do have a PCIII fitted too, and was also thinking it could be a faulty commander which is causing this, however not likely, but a possibility. I also noticed that if you turn the key to the 'off' position for a few seconds, start the bike backup, it rides perfect again - Weird. TPS check via Diagnostics menu shows no faults, but this could be because i have turned the key to the 'off / on' position to get to Yamaha's DIAG menu [reads 16 – 99 btw].. This morning I started the bike up, and it was spitting out black/sooty, kinda wet to the touch exhaust smoke.
RE Power Commander - I suppose i could dis-connect the PC, and see how it rides... ? This would rule out a faulty PCIII I guess.
Has anyone replaced a TPS sensor themselves..? Easy, PITA / Not so bad?
Thanks in advance everyone, i know its been discussed before... but i have a PCIII in the mix
Cheers, vj
