getting fault codes 25 and 26

[r_cordell]

I'm getting falt codes 25 and 26 after i ride for 10 or 15 miles and the sled won't idle, it'll die. After a while longer the codes quit blinking, but the sled still wouldn't run right. As I'm riding, when I'm onthe gas it feels normal, but if you let off the throttle, it sounds a little boggy and the throttle seems touchy. The codes mean there is a malfunction with the cylinder #2 intake air pressure sensor hose or the sensor itself. Once the sled cools down, it runs fine for a while. Most of the riding has been pretty slow, creeping through blowdown timber and powder. Ay ideas?

Have you had the Airbox off latey Make sure the Map sensor for clyinder #2 is SECURLY plugged in. they almsot double click in place. Also make sure the hose that goes to the sensor is attached.

Map sensor are pretty basic sensor appliyng pressure or voltage changed the signal back to the ECu you can test that with a multimeter and a vaccum guage
