P2724: Pressure Control Solenoid E Stuck On — what it means, the affected system and what to check before replacing parts.
Meaning, symptoms, causes and checks
The pressure-control function remains active (ON) when it should release. 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
- 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
