I have a 1500 Classic SLT 3.6l and just started getting this issue today. At first, I thought it was something to do with an electrical issue. The reason I thought that is because on Thanksgiving, my 12v DC outlet fuse blew when using a tire pump. I replaced the fuse and about a week later, my washer fluid stopped spraying. Everything was going fine when I drove the truck last night. Today, I used the remote start and it started right up. As I took my dog out, it shut off (after maybe 2 minutes). Tried to start it again but it honked once and didn't start. That's when I felt like the CEL was on. I started it up with the key and saw the CEL lit up. When I scanned it, I only had the P2681 code. When I got back home, I scanned it again and this time, I also had the P26A7 code. I had the P2681 code earlier this year and had to replace the 3 way valve. I replaced it with the Four Seasons 3 way valve from Rock Auto. I had no issues since and CEL went away with no codes until today. It did get down to -6 recently so not sure if that would affect it since we've had -20 degree and below before with no issues. After digging into the codes, I found the P26A7 could do with the thermostat or the valve but I know the P2681 is for the valve. Not sure where I should start digging into this. I've driven for a while and tried to clear the codes to see if the come back but the CEL doesn't go away. Anyone have any suggestions what it might possibly be?
