P2734Pressure Control Solenoid F Electrical
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2734 is the catch-all electrical code for solenoid F: the driver stage notices coil current or voltage at odds with the command, without saying whether the line is broken, touching ground or touching battery voltage. Public documentation of P2734 by any maker is lacking. Those that publish data on valve F use the specific circuit codes instead: GM's 2025 table 25OBDG03A runs P2736, P2738 and P2739 on the same valve, which there feeds a clutch of the nine- or ten-speed, the line pressure circuit of the eight-speed or the binary pump of the CVT. Ford's 2024 summary maps the odd clutch cooling valve of its TR9070 dual-clutch unit to the same three codes. CARB counts such solenoids as comprehensive components whose circuits must be checked for faults.
