Hi, I left my 2013 6.7 outside and it was in the single didgit temps. I started it once and moved it access the yard and shut it down. Then I started it up and let it warm up for around 10 minutes. The check engine lifht came on. Drove 15 miles to a friends house, let it run for 10 minutes while I went inside. Then got a car wash and hopped on the interstate. I noticed that my boost was around 37 PSI and stuck there (stock truck and didn't run different). I found the next opportunity and pulled over and restarted the rig. Boost was back to normal. Truck never missed a beat or acted odd in any way. I ran over to the auto parts store and checked the code. It said P0069 and something about BARO Manifold Pressure. It couldn't clear with the code reader. Truck still doesn't show any signs of issues and the CEL is off. I do have a NOX code from a known issue. Any thoughts on the new P0069 code or the high boost reading? Thanks!

 

see page 90. Not sure it will tell you what needs to be changed to fix it.

I think I would call it a fluke based upon what you were doing and the cold temps.


Unless it comes back I think I would just leave it alone.

 

That's hand info. Do you have a link to the same data for 2015?

 

I'm glad that the issues went away, CowboyUp!; if they come back, I'd recommend having your dealer diagnose the truck. What's the current mileage on it?

Just got P0069 & P0471 codes. Boost gauge right to the top and engine clattering when I try to accelerate. Not sure if it's something I can fix on the side of the road as I'm sitting in Marathon, TX

Cleared codes,reseated connection running north, fingers bro

 

I was going to say those should let you continue on. MAP and EBP I think are those.

 

After I first cleared them the boost gauge was pegged and engine very noisy. Reseated the connection to the map sensor and it seems to be running OK. Can't tell if the bucking is from wind on the fiver or the engine. In Ft Stockton now waiting for the parts guy to come back from lunch to see if they have a sensor

 

Dealer gave me pn cx-2432 bc3z-9f479-b I'll hold onto it for now and put it in if the codes come back

 

hope that it was just a dirty connection...at least till it is warmer outside.

 

I hope it's just a dirty connection or flaky sensor until I get home at the end of March

Players/Cowboyup! - I hope you get it resolved. I have found that going from hot to extreme cold ad cause sensor issues and they resolve themselves...

 

Thanks Larry!
