Hey guy so I got a 2007 honda cbr600rr. Had a hot start issue from the beginning. So i changed water pump, temp sensor, cleaned radiator. Changed oil and filter and spark plugs.... Changed computer which was bad.
No am getting F1 code to flash.. 2 long and 4 short.. Whats the meaning???
Oh and odometer is reading 270f on start up...

You've already measured resistance/impedance of sensor by itself and measurement shows shorted/bad sensor. Manual says (all measurements are in kilo ohms):

20C = 2.3k - 2.6k ohms
80C = 2.1k - 2.6k ohms
120C = 0.65k-0.73k ohms


As sensor gets hotter and hotter, resistance decreases (NTC type). So your reading of 2.3 ohms is even lower than 120C, thus dash reads even higher. Not sure this is related to 24 O2-sensor code though...
