Default P0125 - Coolant temp for closed loop

Ive been reading some older threads on here to get some ideas but havent found anything that worked for me yet.
Keep getting P0125 - Not enough temperature for closed loop operation. I read it could be the thermostat so i put a new one in, the coolant is full and the light comes on probably 20 mins after being cleared.

I used my low buck scanner to read the ECT and it appears to be 183F on the freeway and about 185-187F around town. I havent been able to capture a blip that could cause the CEL, but am just wondering if anyone know the criteria the ECU is looking to see for the ECT?
