Need help with p20ee
Truck has been throwing p20ee. It’s a 2017 with 37,500 miles roughly. I have a banks idash so I have been trying to monitor all the emissions information I can. So far it seems like nox11 is always reading higher then nox12, changing throttle positions can sometimes make 12 jump higher then 11. I obviously don’t drive the truck much so the def in there is probably close to a year old I only had 1/4 tank left so I put 5 gallons of new stuff on top of it (maybe should have drained the old stuff first). What can I look for to help me out here. I am praying this isn’t going to be a new scr job.
