Does anyone have, or know a source for engine diagnostic codes for a 2012 3.5L Ecoboost?

Mine threw a #111 code likely due to a tuner and changing elevation. I got rid of the code and it likely won't come back, but I'd like to know what the codes mean in greater detail. The #111 code has to do with air intake I believe, likely the MAP sensor.

Thanx in advance for any help!

OBD Codes are not necessarily car specific. You can also just search on Google for the error code. All errors start with a letter P and are 4 digits, so yours would be P0111.
