Turbo Apex code 14

[Spur]

My Apex stops idling and is throwing a code 14. I cleaned all electrical connections and thought I had problem solved. After about an hour of riding it started doing it again. It will not keep idling while stopped, and is impossible to keep running while coming down hills even if I try to assist with the throttle. It seems to get worse at higher elevations. Once you get it started if you can keep it running long enough to engage clutch it drives out ok and won’t die until you let off the throttle. The problem is a little inconsistent. I have left it with a reputable Yamaha repair shop twice. Both times they have not been able to help. Its several hours back to the dealer. Anyone have any ideas I can try from home?

Thanks

Don't know if this will help you but here is what the service manual says about code 14:

Symptom: Faulty intake air pressure sensor hose system; a hose is detached, causing constant application of the atmospheric pressure to the sensor or, the hose is clogged.

Probable cause of malfunction: Intake air pressure sensor hose is detached, clogged, kinked, or pinched. Malfunction in ECU.

Replace your tps, had the same problem with mine i thought it was just a problem with ice in a line then i found out it was the tps. The o-ring that seals the tps lets moisture by and the sled will not idle and runs funny.
