P27D7 Pressure Control Solenoid S Control Circuit Low
Voltage on the pressure control solenoid S control line is below 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.
Is it safe to drive with P27D7?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
Common causes
- Most likelyControl wire shorted to ground
- PossibleInternal short in solenoid coil
