Well fellas I reset everything bought a cummins map sensor so far everything is looking good except I'm still getting p0521 and p0112

And for iat I was getting 4.96v also now have a p0236 code. The map had a good reading of 5

So I'm messing with the map sensor and it's read 3.42 and jumping 4.74 consistent with the truck no running is this normal or is it suppose to stay at a set voltage

I have 2001 dodge 2500 cummins and I keep getting this pain in the butt p0238 code. What could be the causes of this. For the other codes I've already replaced the sensors but yet they are still illuminated I'm new to the diesel life so shine some light on this problem thanks!
