Wiz,
As a refugee of Detroit engine labs of many years, I can tell you that those codes only tell you what the ECU thinks is a problem.
MAPS kind of come in two kinds. There are some that are hard mounted to the throttle body and others are off on a bracket somewhere with a small hose that goes to someplace on the intake.
The ones mounted on the throttle body can get gummed up. They would sometimes accumulate fuel and such. Those can be cleaned with electrical cleaner. Just be real careful to not hit it too hard. If you stick the straw in and hit the button, that may kill it. Be sure to shake it nipple down when you think you are done.
If it is on a hose, check the hose for cracks and blow some solvent through it also check the port where it is attached. Try cleaning it as recommended.
They can go bad, but that was very rare. Our durability test were huge mile equivalent, but run in hours (weeks actually). We never figured out how to do more years in less time.
