P0911Gate Select Actuator Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Plausibility fault in the drive circuit of the gate select actuator of an automated manual gearbox. The circuit is neither open nor shorted, but the current, voltage or response measured on it does not fit the command, for example a current that is too high or too low for the requested movement. No manufacturer documents this code publicly. A Hyundai/Kia patent explains why controllers watch actuator current closely: jamming and sticking raise the motor load, and the motor can be damaged if this is not caught early. An Isuzu patent describes electric select actuators controlled by the transmission module. CARB requires functional checks on such outputs. P0910, P0912 and P0913 are the clear electrical faults, P0909 the failure to reach a gate. Gear changes become slow or are blocked.
- What you may notice
- Check engine or transmission warning light on
- Slow, hesitant or aborted gear changes
- Gearbox enters fallback mode with limited gears
- Likely causes
- LikelyWorn select motor drawing abnormal current
- PossibleStiff select mechanism overloading the actuator
- PossibleHigh resistance in actuator wiring or connector
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Hard · Usually a job for a workshop.Typical cost: €100 – €1,800
