P0069,p0237,p0483 I can not find a code chart.

 

P0069 MAP-Barometric Pressure correlation.

P0237 is for map sensor low voltage.

P0483 cooling fan rationaly check malf.

This is just what I have found, not sure what could couse them.

06 DIESEL

 

The 483 is a nuisance code and wouldn't pay any attention to it. The other 2 typically come up for 2 reasons. The first is the sensor was removed from the intake tube during an intake replacement going from stock to a stage 2 AFE or the like and the truck was started before it was plugged back in. The second is the MAP (intake manifold next to the fuel rail) or the Baro sensor (cold air intake) have gotten dirty for whatever reason. Could be too much oil from a air filter, turbo seal is leaking oil into the intercooler piping and coating the MAP sensor, etc. Or it could be one of a hundred different other things. But those two are the most common.
