P2729 Pressure Control Solenoid E Control Circuit Low
Voltage on the pressure control solenoid E 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 P2729?
Usually safe for short trips, but don’t ignore it: the underlying fault can get more expensive over time.
Common causes
- Most likelyControl wire shorted to ground
- PossibleInternal short in solenoid coil
- Less likelyConnector pins corroded - high contact resistance
