P2723: Pressure Control Solenoid E Performance or Stuck Off — what it means, the affected system and what to check before replacing parts.
Meaning, symptoms, causes and checks
The commanded pressure-control response is unsatisfactory or remains inactive (OFF). Channel E is transmission-specific; the code does not establish the valve location or prove that replacement of this solenoid will correct the hydraulic condition.
Affected system: Transmission pressure-control solenoids
Symptoms
- An engine or transmission warning may appear with rough, delayed or restricted shifts.
- Some vehicles may limit transmission operation or develop excessive operating temperature.
Possible causes
- Pressure-control solenoid E may respond poorly or remain in the inactive position; deposits can contribute to sticking.
- Contaminated or insufficient transmission fluid, restricted hydraulic passages, a valve-body issue or poor electrical connections can affect pressure regulation.
What to check
- Confirm P2723 and read other transmission codes before assigning a component fault.
- Check transmission-fluid level and condition using the gearbox-specific procedure; inspect accessible plugs and wiring.
- Compare the commanded and actual response of pressure-control solenoid E with service data before opening the hydraulic assembly.
