No new mods or other changes to my truck...havent ever had this code and now i've gotten it 4x's in the past month....put's the truck in reduced power mode....

Any common causes? e.g. boost leak, boost fooler issue, reset apps/throttle by wire? Truck run's fine otherwise so not sure....

Thoughts appreciated.

 

this code is usually associated with the 14 cm housings. i have never seen the 62-65- 13 throw this code. try changing the map sensor, i think it might be reporting the incorrect pressure. check for boot leaks. your 06 has the metal ends on the intercooler so check it last

 

I used to get this code pretty often and tried everything to figure it out however nothing worked and I just lived with pulling over and clearing the code with the Smarty.

Come to think of it I have not had the code since I did the new intake. I know my old set up had a very dirty filter which may have been restricting flow.

Maybe check your intake and filter for restrictions.

 

use a wix 49946 filter
