P2727: Pressure Control Solenoid E Control Circuit / Open — what it means, the affected system and what to check before replacing parts.
Meaning, symptoms, causes and checks
Pressure-control solenoid E command: The monitor reports a circuit/open condition. The wiring arrangement must be identified before interpreting continuity. The letter E identifies a control channel, not a universal valve location. An electrical control-circuit result must be distinguished from the valve's hydraulic response.
Affected system: Transmission pressure-control solenoids
Symptoms
- Warning light may illuminate
- Related system function may be impaired
- Vehicle-specific symptoms vary
Possible causes
- Transmission fluid, hydraulic, solenoid, connector, or control-circuit issue
- Related wiring, connector, power or ground fault
- Vehicle-specific mechanical or control issue
What to check
- Record stored and pending codes and freeze-frame data
- Compare commanded and actual transmission data, inspect fluid condition and level according to the vehicle procedure, then test the relevant circuit and solenoid.
- Confirm measured values against the vehicle service information
- Retest under the conditions that set the code
- Compare commanded and actual transmission data, inspect fluid condition and level according to the vehicle procedure, then test the relevant circuit and solenoid.
- Repair the verified cause and confirm the code does not return
Also written as: P2727-00, P272700 (some scan tools add the fault-type byte, e.g. -00).
