I have a 2012 ford f350 6.7 diesel....I have the following check engine light codes..

P0073 Ambient air sensor circuit high output
P009a Intake air and/ambient air correlation.

I replaced ambient air sensor in passenger mirror and auto zone said to replace the air charge sensor. I have done both still have a check engine light. Please help

 

The ambient air sensor in the mirror has nothing to do with a check engine light.
Next look at the air intake and make sure that all the connections to the engine are tight and no leaks. Check the connections to the turbos, intercooler are not damaged.
If you find no leaks or anything just take it to the dealer and let them fix it.
