I'm looking for some input on a check engine light (solid) that just showed up on my 2015 Ram ecodiesel. I checked it with a code reader and it came back with "P1288 SRV Solenoid CKT", cleared the code and it came back shortly after. The truck is running fine, except the remote start is a little wonky...it'll start and usually shut itself off when I get in the truck. I tried googling this error code, and couldn't find much.

Anyone else ever have this code? Anyone know what the problem might be?

I'm wondering if this can wait until next scheduled maintenance or this needs a dealer visit immediately? I'm not close to a dealer, so getting the truck into the shop isn't easy.

Update: Just heard back from the dealer, they said the P1288 code is actaully:

"cylinder temp sensor out of self-test range"

They said it's fine to drive since it's not flashing. Anyone ever have this problem?

all I had was this :

P1288-00 = NOX sensor 1/2 zero offset too high
P1289-00 = NOX sensor 1/2 zero offset too low

I added your info in my error codes file ,Thanks
