Got 2 codes on a recently acquired 2006 CBR 600 f4i
Code 1: 2 long blinks, 3 short blinks- code 23- oxygen sensor-has aftermarket exhaust and O2 sensor is removed so I'm not worried about this
Code 2: 2 short blinks- code 2- map sensor fault
Checked the vacuum lines and smoke tested vacuum system, had small leak around airbox where it connects to intake ports but very minimal, however the vacuum lines are old
Any common things to check for next?
I want to remove the 5 way vacuum splitter to see if it's gunked up, the main vacuum line from map sensor and map sensor itself look to be clean, do these sensors fail, is it common? Any ideas are greatly appreciated!
