Lol, all that brain power just to unplug and reset the ecu! Glad you got it working again...
I would suspect a bad water temp sensor or ECU or Both...hey bro sorry for taking so long to get back, fan does run with sensor unplugged so what does that mean??
Mine was bad and never turned the light on. Truth of the matter is the inside of the sensor has to fry into, or your wire has to get damaged or disconnected to make the EFI light come on for a water temp sensor issue. Wiring short or open is all it codes.well the light does not come on unless i unplug the switch which makes the fan stay on as well as the light the whole time so what do u think? ecu or sensor? and if sensor where would i get one? Thanks for your help bro!
Sounds like a bad relay (not closing inside). Try swapping it with one of the relays that has a brown wire running into it.Duster
I have similar problems on a machine i just bought used.
fan has never come on after 2 rides, last ride it overheated and light came on. i found the fuse blown. replaced it and no luck.
i have checked everything and replaced the water temp sensor and ECU with a procom and still no luck.
the only way i can get the fan to run is to short the pink/blue to ground at the relay connection and the fan comes right on.
the relay tests good but i have not replaced it.
any ideas? i'm just totally frustrated at this point.
