My bike had been experiencing on and off high RPM idling for some time, but right now it is working fine. How would you like me to provide you this information? I can scan it and email it if you would like.
Thanks for the offer and the quick reply.
My sensor was stuck at open circuit (so after actually pulling it out, it's obvious and I guess I don't need the instructions from the manual).
For diagnosis. After checking several other parts (IAC, throttle blades closing fully, TPS reset) I pulled the connector from the EOT sensor and it immediately dropped to perfect idle, from this I assumed it must be getting a false reading from the sensor.
Checking it like any other temp sensor, I checked at the connector the reference voltage (perfect 5vdc) and the ground (0vdc) and then at the sensor itself for resistance (which for mine showed open circuit). I think these sensors should start at around 2kohms and taper off to near zero when they get hot. The actual voltages or resistances should be in the manual.
I've never seen a temperature sensor fail intermittently, though I guess it could be possible. If I had to guess, our problems aren't the same -- though my bike did occasionally idle high or low when it got really hot for a while now. I'll have to see if that changes after the part gets swapped.
