FI light just started blinking 1x long, 2x short on startup but bike runs normally and fan comes on when engine is hot

What is going on?

It is the BMW 318 sensor with lower cut in temp
 
Hi guys
I got the 2009 FE 450
Same for me 1 Long / 2 shorts (+ sometime some random half blinks)
Engine run fabulous but it have some random cut off when hot. I have replaced the "pick up" sensor as he die recently.
Today i will swap the injector, but it seem that the one in place was working good...
Any idea?

Click to expand...
1x L, 2x S usually, not always, points to
coolant temp sensor.
this sensor is bolted into the engine to read coolant temp inside the motor.

The bmw sensor on the radiator is aka a fan switch. It's normally not recognized as a temp sensor.
 
Eng tem sensor is next to the plug.
Im gonna to check my 2009 wires for oxidation:rolleyes:, as KTM is too poor to built with marine grade wires real offroad bikes spending $ in orange paint...
