LBZ: MAP sensor throwing check engine light, things to check for?

[SouthTexasDuramax]

My '06 Duramax is throwing an engine code linked to the MAP. I am running a K&N cleanable air filter, it's been on pretty much since I've had the truck. What are things to check for to diagnose the code?

Thanks in advance!

See if this helps. I ended up replacing the MAF and MAP sensors, used some electrical cleaner and the issue resolved itself.

As I was told, it helps to have the code(s) that is/are being thrown
