Perhaps, but I have yet to see it mentioned on forums or re: diag, only mentioned on parts websites.

FWIW my GFs diesel jeep (2.8 turbo, '05.. Fairly modern design) has a MAP sensor and it gets NASTY thanks to tons of erg/recirculating pcv and other oil vapors through intake system. Causes lots of boost and other engine problems but it is the primary air/fuel sensor as there is no vacuum in a diesel thus no MAF sensor (hers has a MAF technically but it's only used for EGR and emissions).

Sounds like the AJ 4.4 uses as cross correction against MAF, but again I've heard zero mention of it.

 

Since it threw multiple codes for it, it's certainly a good place to start troubleshooting. I'm not saying replace it. Unless it's cheap.

 

Update: I tried cleaning the EGR valve which didn't help the issue, so I ended up replacing it. Surprisingly, it seems to have fixed the problem. Took all of 30 minutes and $200. I replaced it last Saturday and have had no problems since (and I would have had problems by now). Just wanted to post an update in case anyone in the future has a similar issue.
