What does code P26A6 mean?

Q: What does code P26A6 mean?

Engine Coolant Bypass Valve A Position Sensor Circuit Low. P26A6 means the powertrain control module (PCM) has detected a low-voltage signal from the position sensor inside the engine coolant bypass valve, which is the valve that routes coolant around the radiator to speed warm-up. The sensor circuit is reporting a voltage below the expected range, so the PCM cannot trust the valve's actual position.
