Don't quote me, but I think it's a diagnostic code 3 to test the sensor, have to do a search for the expected results, can get back latter on today.
The sensor is up near the fuel rail, it's air tube can get pinched or perish.
Likewise the coolant temp sensor has a lot to do with the initial basemap for the FI.
Do you use ethanol fuel, the times I've had to use it the consumption drops quite a bit. Don't know where you live, but do you have summer / winter fuels ??
The Gen1 service manual gives a real good writeup on the FI System and how to check the various sensors.
Give the bike a good run, chuck in some injector cleaner and check the codes once more.
