I have a 2004 with 30,000+ miles on it and just recently started getting the error code 46 and 13 . When i start the bike cold the far left header (if your standing on the shift side looking forward to the front of bike) is not hot and will not get hot. When this issue started i was running it hard (fast as **** boi hard) and the temp outside was cold af. The diag. code says its a Intake Air Pressure sensor fault . Im thinking its the coil pak or plug and not the sensor. Ive got a full yoshi exhaust , new air filter, has block off plates and i just finshed lapping and polishing the heads and valves. The code 46 is what is causing me to second guess my common sense. Has anyone got any ideas or suggestions on this issue ?
