CEL came on last week on my 2020 Ecodiesel for P0407 EGR Valve Position sensor B - low input. Truck runs fine otherwise. I've cleared the code a few times and it seems to come back after a few days. I have 37,500 on my truck so it's out of warranty for EGR. Dealer claims they tested wiring and power and ground check good so they recommend new EGR sensor for $1300. Thoughts other than a delete? I live in a state with emissions testing. Thanks!
