P2D7FCharging Start Switch Circuit High

P2D7F indicates that the powertrain control module (PCM) has detected an abnormally high voltage on the charging start switch circuit, which is the input that tells the module the driver has requested the charging system to begin energizing. The PCM expects a specific voltage range on this circuit and sets the code when the signal exceeds the upper threshold, typically because the circuit is shorted to voltage or the switch contacts have failed open.
