Reply With QuoteI'm thinking engine temp sensor, but the odd thing is last time I rode it the fan functioned fine, and on this day now it's done?
Help, I turn the ignition , hear the fuel pump prime, and within half a second the fan kicks in, I turn the key off, wait for 30 seconds, then the fan switches to the 1/2 speed, and then off, each time I turn the ignition on the fan will turn back on. When I hit the started I can hear it cranking, so it has plenty of battery power, tried taking off the cables from the battery, hooked it back up and same problem, and suggestions?

Temp sensor, probably fouled the plugs.
Just ordered 2 new plugs, I figure if I'm already in there replacing the sensor might as well just be safe and do the plugs, anyone know the best deal for the sensor or have the part #, 05 XB9R
nik: don't know if in conjunction you're also getting a CEL activation but agree it sounds like rear head temp sensor. there is no suitable aftermarket or automotive application sensor i am aware of. either evilbay or surdyke.com probably best pricing. here's your part # son.
Buell part #P1278.K which superseded part #Y0605.K
Thanks lunatic, placed the order, I'll give an update once it's replaced!
I do know depending on how the temp sensor failed (failed open or fail closed circuit), sometimes they will fail open and continuously read the bike is overheating when in actuality it's ice cold. Just good for thought to put your mind at ease lol if it did then it most definitely Italy won't let it start but try to cool it off
Hoping that's it TC, still waiting on the parts, I hate ordering and waiting on HD :(
Replaced the sensor, wasn't the problem, now dropped 100$ just to replace a sensor that wasn't bad *(&^(*&(&*%)^(). Any ideas?
A lot of diagnostics data can be gathered if you have a data link cable and ECMSpy or TunerPro RT.
Even though you replaced the ET Sensor, what does the ECM think the engine temperature is?
Are there any historic, functional, or current trouble codes?
