P2709Shift 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
- P2709 flags an electrical fault on shift solenoid F, found by the output driver rather than by watching the gearbox shift. Hyundai and Kia list it as the circuit code for that valve: Kia bulletin TRA 051 and Hyundai 15-AT-010 call solenoid F SS-B on their six-speed transaxles and replace parts instead of the gearbox, Kia first the solenoid, then the harness to the PCM, and only then the PCM if the code returns; Hyundai 12-AT-015-1 does the same for the 2012-2013 Genesis eight-speed. Ford is inconsistent: its 2024 summary text sends shorts on solenoid F to P0998/P0999, yet its tables give P2709 for a short to ground on 10R and 8F35/8F40 units and as the general electrical fault on 8F57/8F24, flagged after 1.5 s of driver feedback. Shifts using that clutch are lost.
- What you may notice
- MIL lit and transmission in a fail-safe gear
- Missing gears or sudden harsh shifts
- Code returns immediately after clearing if the fault is permanent
- Likely causes
- LikelyDefective coil in shift solenoid F (Hyundai/Kia replace the solenoid first)
- PossibleChafed or corroded wiring or connector between PCM/TCM and transmission
- PossibleDamaged internal transmission harness or lead frame
- RareFaulty output driver in the PCM/TCM
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
