Limp Mode - Many codes

[Ozer]

Ugh, now im getting the passive tank sensor error.
I used Peak DEF to refill it, i wonder if that has anything to do with it.

UPDATE:
After some wire checking with the volt meter, i concluded that the wires are fine.
I read here in a post that MAF throws a cell but the AIT doesnt when they go bad. Since i replaced the AIT already and still got the same codes, i concluded that the MAF was bad.
Ordered one from RockAuto ($189) and installed it.
The new MAF fixed the issues i been having with the sensors. Still have the DEF codes but those are differen issues.

Thanks for the help from fellas who directed me in checking the wires and for giving insight.

Rock Auto price was the cheapest i seen for a OEM BOSCH part so go check them out of you need a MAF or other parts. (Im not affiliated with them at all)
