Just got the code for P20B9 looks like my heaters went out, $249 for the parts will see how changing them goes when I get a min to do it.

I know mine went out and the dealership just changed the tank. Maybe they stuck it to GM and found it was quicker just to replace the tank and not fool with disassembling it to replace the heaters. Too it seems like I read where you couldn't just replace those.
I wonder if this would take care of my P205b temp sensor issue?? Might be worth looking into till I get to where I can delete everything.
I had a heater code which would prevent my remote start from working until cleared. The dealer replaced the whole tank under warranty. Delete is on the way though I can't wait!!
Not entirely true I have a door module code that reoccurs frequently and does not prevent remote starts. I also had an oil pressure sender go bad which would throw a stop engine message and it would still remote start! Delete is on it's way and I have a free Dyno day at my cousins shop next weekend ����

Yes the temp sensor is part of the sending unit but there is also a temp sensor module on top of the tank that the recommend replacing along with the sending unit. Both should be covered under the 10/120 warranty
Everybody who has a Diesel Particulate Filter and DEF tank WILL have an issue with the tank heater and then probably the DEF pump. It is not a matter of if it will go bad but when. And it will probably happen right after the 120,000 mile mark. That Urea crap is extremely corrosive and it is going to corrode the heater. I just had this happen and am the 3rd person I know it happen to recently. My brother went to South Carolina and it got a little cold up there a few days ago and his truck went into limp mode. Had to drive straight to the dealer and they told him it was DEF heater. He had about 120,050 miles on his truck and they replaced the heater and fudged the numbers to do it under warranty. Then they sent him on his way and headed home back to Florida and as soon as he got home the DEF pump went out and again went to limp mode and had to go straight to dealer. Would not cover under warranty and had to spend $950 to replace the pump. 2 days later I had the exact same thing happen to my truck here in Central Florida where the temperature dipped into the 40's. My truck had 121,000 miles on it. I took it straight to dealer and they told me it was just out of warranty and i would have to pay to fix it. No way in hell was that going to happen as I know it will just happen again some time down the road. I ordered the EZ link programmer with exhaust, EGR delete and cold air intake. Should have done it when it was new.
