Nox codes i think?

DTC P22FE00
DTC P229E13
DTC P22A100
DTC P220F93

The first one and fourth one have stopped dinging for events, but middle two have still pinged last couple days. My cel first came on when i had bluetooth headset plugged in while driving which i normally dont do cuz truck is electronically sensitive i would say with this eld plugged straight to the fuse panel and my relays started clicking like crazy so i unplugged it and my cb too, but codes cleared themselves away later that same day although light stayed on. Then couple days later i notice all these are now active. I called volvo guy, he said they point to nox sensor (bank 1 sensor 2) get it to a shop when i can, made seem like it wasnt a life or death situation for my truck. Jus wondering if sensor 2 means nox outlet sensor possibly bad? Changed my 20amp nox fuse under hood and it's got power, not sure if there are any other electrical places i could check just find it funny this all happened after my relays went crazy having too much power sucking i guess

 

Yes needed new nox sensor dang thing was $688.11, part # 22303391

 

Yup think that is what he said, i prob shoulda changed inlet too
