This code keeps coming up with CEL tried resetting it but it keeps coming on 3rd time. This only happens when the ICE comes on and at outside temps of 32-35 degrees. Anyone else having this code, and any fixes.

Your generic code reader might not pick up the codes if they are stored in the Hybrid system

That could be possible also I received a bulletin about the heat degrading in stealth mode with my code. With this CEL only happening when it's cold @ 32 degress, with heat being used. So I'm leaning towards the

REPAIR/RECOMMENDATION:
An updated thermostatic check valve has been released that raises the thermostat’s opening temperature to 65° C which will resolve the condition."

I know this hasn't been done since my Karma was of a California origin, before it made it to the east coast. Also this is the first temp of probably 35 to 30 that the karma has been driven in.

I will be checking in with Lormax to see if he can fit me in next week.

Hope I can find this part the CEL is an annoying sight.
