At the very end of our ride Sunday my sled would not idle or idle like crap. It would run fine when above 2500 rpms but would struggle at idle and give me a check engine light with code 13. I have the service manual and see that it is a fault with air intake pressure sensor 1 which could be a bad sensor or connection. The sensor it is referring to is the throttle bodies air pressure sensor not the outside air pressure sensor. Anybody have this problem or remember seeing this problem before?

I had a code 14 on a sled a week or so ago. You can check the sensor in the diagnostics of the gauge cluster. I pulled the line off the sensor and blew air through it to make sure it wasn't pinched/plugged and it has been working fine since.
The code #13 is the sensor "12" on that picture. It will be closest to the clutches. Remove the seat, fuel tank, etc and you can get to it from there.

You're right, I looked at the picture too quickly. It is the sensor towards the chaincase side!

Fix this problem. Diagnostics mode works great and I highly suggest using it for any problem you may have with a sensor, INCLUDING T.O.R.S, but I found all my air pressure sensor within range of what they are supposed to be so it didn't help me but was still kinda neat. So I started taking things apart (seat, tank, spark plugs, steering post, air box, thorttle boddies, and moved wiring to get everything off) I found three problems it could:
1. Oil every where in the throttle bodies including some of the vent lines that went to the sensor. (from rolling sled over out west)
2. Main wiring harness was rubbing on the frame around the place where the service update was done.
3. Exhaust flex joint clamp on cylinder #3 was lying in the bottom of the heat shield, donut was still in good condition just the clamp fell off.
After fixing all three of these and replacing the spark plugs in starts up very easily and idles good. It is mostly something to do with all the oil in the throttle bodies, I cleaned my air box out after my west trip but it seems some must have gotten sucked in before I clean it.
