P0913Gate Select Actuator Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Set when the drive circuit of the gate select actuator of an automated manual gearbox shows a voltage that is too high for the current switching state. Usual causes are a short of a motor or control line to battery voltage, or a driver stage in the module that no longer switches off; depending on the circuit design an open load can also read high. No manufacturer documents this code publicly. Patents by Isuzu and Hyundai/Kia describe electric select and shift actuators that the transmission controller powers directly, and CARB requires circuit checks on such outputs. P0912 is the opposite low fault, P0910 the open circuit, P0911 the plausibility fault and P0909 a select movement that misses its gate. The driver sees a warning lamp and a gearbox that can no longer change gates.
- What you may notice
- Check engine or transmission warning light on
- Gearbox stops changing gates or holds one gear
- Actuator may run noisily or get hot
- Likely causes
- LikelyActuator wire shorted to battery voltage
- PossibleOpen motor winding read as high voltage by the driver stage
- RareDriver stage in the transmission control module stuck on
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
