What the source says
The documented condition
Subaru extended warranty coverage for the thermo control valve on specified Outback model years after identifying that coolant vapor could enter the sensor portion of the valve. That condition can set P2682 or P26A-series codes. The codes must be read and the vehicle checked because unrelated cooling, wiring and sensor faults can produce similar warnings.

Repair paths and safe checks
Match the action to the evidence.
Run a coverage inquiry and replace the valve if confirmed
Ask a Subaru retailer to read the stored codes, check the VIN for the active extension and follow the service-manual thermo control valve replacement procedure when the condition is confirmed.
The procedure involves the cooling system, fuel delivery pipe and one-time-use gaskets. It is intended for trained technicians.
Save the codes and check coolant only when cold
Save a scan report before clearing anything. Once the engine is completely cold and on level ground, compare the reservoir level with the owner's manual marks and photograph any warnings for the service visit.
Never open a hot cooling system. A code match is not confirmation that the valve is the only fault.
