Hello, I’m in desperate need of help especially after visiting the dealer today costing me 2 hours of labor without results.
I started out with codes P20EE, P2BA9, and if I remember correctly, P1288 NOx sensors.
I replaced the NOx sensors, dropped the tank, removed all the def and replaced the with new blue def.
Reinstalled the tank and noticed the def gauge was not correct so I purchased a new tank with new pump and new injector. Drove the truck on the highway for about 20 miles and scanned for codes when I returned and no codes came up. However, the countdown see dealer for def service did not go way and it ended up with 0 miles and the truck wouldn’t restart. The dealer ended up extending the miles to 40 and told me to drive so it could regenerate codes. I drove it for about 20 miles and still no codes.
Does anyone have any suggestion?
