There have been a few posts lately where the heater control valve were clogged or defective.

You will get codes when disconnecting sensors or other control parts, this can be normal so I would not get too overly concerned.

I would say plan on replacing the heater control valve and hope this resolves your problem.

You may see obvious problems once you remove it??
