So, my 2019 2500HD has decided to start throwing the P1050 code. I understand what it means..... I cleared the code and added 2.5 gallons of DEF hoping to at least get by for a time. I'm in the middle of a move 175 miles away, and right now I don't have time to give up the truck for any repairs - the closing on this house is in one week and we need to get out. The code went away after adding DEF a few days ago, and the DEF level showed OK, but now, after another 350-mile round trip, the MIL is back on and the level readout is the usual - - . I'm getting 14.5 MPG pulling a 5,000lb trailer so I expect more DEF consumption with the lower mileage. I'm going to get it fixed, but my fear is that at some point the truck will put me in reduced power mode. Can anyone tell me the operating strategy when the P1050 code is stored? Do I add another 2.5 gallons of DEF and hope not to overfill the tank? Next week I need to pull a 10K camper that 175-mile distance, and I do NOT want to get stuck. Any constructive advice would be greatly appreciated. TIA

Whats the status with p1050? I received the same code and found a faulty connection on top of def tank. I reached up jiggled wires and light went out. Need to drop tank to properly clean connections.
Ah. First reply, thank you. I've found that adding a jug of def the light will go out for a while. The light is on now, but before I add more def I'll go out and wiggle the harness and see if that fixes it. We are in between houses and living in a campground until we close next week. There's been lots of rain so the ground is pretty wet. Next time I take the truck out I'll borrow a concrete pad at an empty site and try the wiggle the harness thing.
Hello . Have you found the fix yet. My light reappeared. I believe it might be a stuck float in def tank. I believe when I let the tank get low. The air allows crystallization to form on pump unit preventing the float from moving. My guess . What do you think?
Crap. Just posted a long reply and it bombed. I have been filling the DEF tank to overflowing whenever the CEL comes on, and that seems to help for a while. We are still getting moved into our house so getting the truck fixed has taken a back seat. You could be right about a stuck float, but the code tells us the sensor is 'out of range' so my perception is that is an electrical issue more than a mechanical (float) issue. The issue seems to be sporadic so I'm not sure what to think. I've got to get it fixed, sooner than later. I'll update this thread as I learn things. Keep me posted as well.
Sorry for delay in updating this thread; as I mentioned earlier, wifey was very sick, and at one point I thought I would lose her. She has finally recovered and is back to her old self. Our last doctor visit was today, and he has given her a clean bill of health.
The P1050 code kept coming back over the months and looking at the DEF level on the DIC I could see that the failure was very intermittent at times. At others, it was a hard failure. One pattern did emerge, and that was in the mornings when it was cool out (relatively speaking in Florida) the level reading was normal. After a long drive, or after a shorter drive and hot soak, it would fail.
I took the truck to a local shop to have the oil changed before our trip to the Keys and at that time I had them pull the DEF tank cover, disconnect the harnesses, and apply electrical contact grease. (NOT dielectric grease) That seemed to have no effect on the issue so my best guess is the pump assembly will need to be replaced.
Here comes the 'fun' part: during our trip to the keys the P0191 code set with the even more dreaded 'reduced engine power' message and you guessed it. Almost NO power. Imagine being in bumper to bumper traffic and having that failure. Pulling a camper. Thankfully I had my little scan tool and was able to clear the code and continue driving. It happened two more times, and after that we had no problems with it. The entire week we were in Key Largo presented no problems (although the DEF circuit failure came went 'as usual.' That was great ......... until the trip home. We made it up and off US1 and into Homestead and things got really 'fun.' Seven P0191 circuit failures at the most inopportune times until we got out of Homestead and onto the interstate and after that, no problems. The service bulletin that addresses the code P0191 recommends replacing the connector at the pressure sensor, which I did two years ago.
After that ride home wifey declares the truck is probably possessed (half jokingly) and no longer should be in our world. So..... I found a 2022 Silverado 2500HD diesel at a Ford dealer (really?) with all of 6,600 miles on it and in spotless condition. The darned thing still has that new vehicle smell to it! We got it for 4K under market, and they gave us 45K trade in value for the now 'possessed' 2019 Silverado.
In the end, I wished I had been able to finally have a confirmed fix to share, but it just wasn't meant to be. Thanks to all for their input, I do appreciate it.
