P2680Coolant Degassing Valve Control Circuit High

⚙️ Powertrain (Motor y Transmisión)
Moderada

Voltage on the coolant degassing valve control line is above the expected window. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
