Hi All! Started my ST1300 today for the first time since last fall and the FI light came on showing a Code 2 error. Bike was in the garage during some construction works this winter and there was a lot of dust. I wonder if this can be related? I tried to reset the code following the procedure found in the forum with the jumper but keeps coming back. Starts normally and FI indicator is not flashing. It starts flashing as soon as the engine start to rev a little faster during warm up. Doesn’t go away after. Thanks in advance for your help and I wish you all a great motorcycle season!

Often is a plugged up five-way Tee (vacuum hose issue).

Article [13] - ST1300 - FI Codes (MIL) Malfunction Indicator Lamp | ST1300 Articles

The PGM-FI MIL denotes the failure codes (the number of blinks from 0 thru 33). When the indicator lights for 1.3 seconds it is equivalent to 10 blinks. When more than one failure occurs, the MIL shows the blinks in order of lowest to highest number. Code Reset: Turn the engine stop switch...

Yup, code 2 is for the MAP sensor except it’s usually not actually a faulty sensor but rather the 5-way T and or one or more of the vacuum lines are plugged.

Thanks for the reply. Is there by any chance a video on that « procedure » somewhere?

It's some work to get to it, you have to raise the tank and remove the air box.

Easier access if you remove the upper tank (run it dry first, to flashing tank level lights).

Try searching the site on this 5-way Tee.

It is not very sturdy, so best to have one or two spares on hand before you get there and disconnect/connect it from the vacuum lines.

And while you are there.....many have changed the length/routing of the vacuum lines to raise the 5-way so it is not on the bottom of this vacuum manifold like it is now and where it can collect slush and plugs up. Worth doing while you are at it.

Not a quick job!
 
SO I found this 5-way tee and it was indeed clogged with some dirt. Cleaned it all up and took some time to clean the air intake piece which was also dirty. When I was replacing the cover, I noticed some oil splashed in the inside…see pics. Is this normal or is this something to be worried about?

That is just blow by from the crank case breather hose (forward hose on bottom of airbox)
Caution, do not use any spray or cleaner along the inside sealing rim of the airbox cover, it is foam and will easily be damaged.
Gently use some q-tips to wipe away the oil in the channel.
You would be best served to replace the vacuum lines with new ones, or you will risk air leaks after to take it apart then put it back together.
