What does code P26A7 mean?

Q: What does code P26A7 mean?

Engine Coolant Bypass Valve A Position Sensor Circuit High. P26A7 indicates that the engine control module has detected an abnormally high voltage on the signal circuit of the engine coolant bypass valve position sensor for circuit A. This high voltage reading typically means the sensor signal wire is shorted to a voltage source or the sensor's internal ground reference has failed, causing the computer to see a position that is higher than physically possible.
