Attention Turbo Gurus!!!

[BOOST]

Just purchased an 07 apex with MCXpress turbo. Heading to revy. in a couple days and just ran the thing around the yard a few times to test it out. Was ok for the first few times, but now keeps throwing a code. If its outside and cold, sometimes, it wont fire up great and code 23 is up. I get it running and take it out and it runs alright. Bring it in the shop shut it down, fire it back up and its fine. Take her out again and its ok for run, then throws 23 again. One time I noticed it wouldn't throw it if you just putted around, but as soon as it builds some boost, it throws it. It wont idle on its own if the code is flashing. It also threw 14 a couple times, but not as often. I saw a chart and 23 is supposed to do with the atmospheric pressure sensor, 14 is air intake pressure sensor. It's intermiditant which kind of worries me ( after all I also own a 900 polaris!) Anybody got any ideas?? Would be muchly appreciated. I dont want to have a bad start with this thing as I hear the ranting and raving about them. Thanks for the time guys!! MJ

The atmospheric pressure sensor is unpluged or shorted out.That's the one under the intercooler down by the bottom of the battery.

spunds like you have moisture in the line from your itercooler to your sensor , mine did it last year. i cut the line from cooler to sensor and put in a tee and drop tube to catch moisture. is your air cleaner still under the seat like the stock kit from mc? if it is the turbo melts the snow and sucks that water to your cooler and gets to your sensor. hope this works for ya.

Mount the sensor so it can not get moisture inside of it. There should be no hoses or lines hooked up to it. If there is something hooked up to it, then take it off and try it. Been there done that.

ya it was the barometric pressure sensor aperantly. As far as i know there is a vaccum line hooked to it. Ya i rode it this weekend and noticed that the sensor were covered in snow in the engine compartment, wondering what i should do to keep em clean.
