P2739: Pressure Control Solenoid F Control Circuit High — what it means, the affected system and what to check before replacing parts.
Meaning, symptoms, causes and checks
Pressure-control solenoid F command: The monitored electrical value is above its permitted range. This is an electrical finding, not an instruction to replace the monitored component. The letter F 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: P2739-00, P273900 (some scan tools add the fault-type byte, e.g. -00).
