P20EE / P1288 (2018 ram 1500 eco diesel)

Hey guys, looking for some input here. (Canada)

Those 2 codes popped up on my truck and took it to the dealership. They said that the NOX sensors aren’t working right and that’s probably the issue. I asked to have the def injector tested or other DPF parts and I was told if they did they would charge more Diagnostic time.

They quoted me $2,700 Canadian to replace the Nox sensors, which I think it’s outrageous. I refused but obviously I got charged the 230 diag fee. Although tbh if I’m gonna spend that kind of money, then I will spend it on deleting the emmissions part.

My thought is to remove and clean the sensors myself as I hear people say that that’s often the problem, specially in my case, that I drive lots of short distances etc. if that fixes the problem, great. If not, then it maybe will fix the sensor problem at least and then they will fix my DPF for free.

Note that I say free because my truck only has 50k miles or 80k kms and it has major emissions warranty. The silly thing in my head is that the nox sensors aren’t considered to be under this warranty.

All input is welcome please!
