P2727
Pressure Control Solenoid E Control Circuit/Open
Automatic transmission (pressure control solenoid)
Generic OBD-II
Medium
What it means
P2727 means the control circuit for the transmission's pressure control solenoid 'E' is open or out of range, so the module can't properly command line pressure. Expect harsh shifts, slipping, or a protective limp mode. It's usually an open wire, a bad connector, or a failed solenoid — the engine still starts and runs normally.
Medium
Can I keep driving? Yes but with care — an open solenoid circuit can cause harsh shifts, slipping, or limp mode; extended driving risks transmission wear, so repair soon.
Common symptoms
What you'll notice
- Harsh or erratic shifts
- Transmission slipping
- Limp mode (fixed gear)
- Check-engine light on
Common causes
Most likely first
- Open in the solenoid E control circuitLikely
- Corroded or loose solenoid connectorCommon
- Faulty pressure control solenoid ECommon
- Damaged internal transmission harnessLess often
- Transmission control module fault (least likely)Less often
How to diagnose & fix
Work through it in order
- Check transmission fluid level and condition.
- Inspect the solenoid connector and internal harness for an open or corrosion.
- Back-probe and measure solenoid E resistance against spec (an open reads infinite).
- Repair or replace the internal harness if the open is there.
- Replace the solenoid if it fails; consider the module only after wiring checks out.
FAQ
Quick answers
Is it safe to drive with P2727?+
Short-term, gently. The transmission may shift harshly, slip, or limp. Slipping causes wear, so have it diagnosed soon.
Can I just clear P2727?+
You can, but an open circuit or failed solenoid will set it again. Fix the wiring or solenoid rather than relying on a clear.
