P20BD & P20EE :(

[FullyRox]

Hi everyone,

I’m new to the forum. I bought a 2017 1500 Big Horn three weeks ago. Love the truck!

Last week I used the remote starter and it failed, gave me a P20BD error (Reductant Heater B). I took it into the dealership and they changed the DEF heater line and an injector ($1600). Tried the remote this morning and got a P20EE error (Catalyst Efficiency Below Threshold Level). This seems kinda suspect given the work I just had done, has anyone experienced this before? I’m calling the dealership Tuesday morning, just wondering if I’m in for a long haul of issues.
Any thoughts?

Heck, a lot of times they are just throwing parts at emissions codes. Did all of these start with the remote starter ?

That was the cause of the first error (P20BD) after “fixing” that it gave me P20EE when I tried it again.
