Engine code P06A3

I keeping getting this P06A3 engine code (P06A3 Sensor Reference Voltage D Circuit Open). That's the only code. The truck is a 2015 (early build) duramax with 126k. It is deleted with kory willis tune and Ez Lynk tuner and blocker plates. The truck has been deleted for over a year with no issues. I have tried clearing the codes, different tunes, unhooking the batteries to reset the system and running out of ideas, checking connection on egr valves( which shouldn't matter). Any ideas guys? Thanks in advance!
