P2738 — Pressure Control Solenoid F Control Circuit Low

Pressure-control solenoid F command: The monitored electrical value is below its permitted range. This signal-level finding does not by itself establish a mechanical failure. 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: P2738-00, P273800 (some scan tools add the fault-type byte, e.g. -00).
