Diagnosing and Repairing Gearbox Actuator Faults – Toyota & Peugeot
Gearbox actuator faults are a known issue affecting several small Toyota and Peugeot models, including the Toyota Yaris, Aygo, Auris and the Peugeot 107. These faults can cause gear selection problems, flashing dash warnings, or even prevent the vehicle from starting. In this post, we’ll cover how to recognise the symptoms, diagnose the fault, and outline the repair options available to get your vehicle shifting smoothly again.
Common Faults:
- Randomly drops into neutral
- Stuck in gear
- No gear selection at all
- Transmission warning light
Common fault codes:
- P0909 – Transmission Gate Selection Error
- P0919 – Gear Shift Position Control Error
Common Faults and Diagnosis
Fault Code P0909 – Transmission Gate Selection Error
This code indicates the actuator is unable to correctly select the intended gear gate position. It typically arises when the internal gear selector motor struggles to align with the expected position due to wear, electrical failure, or resistance in the mechanical linkage. In practice, this may result in the vehicle being stuck in neutral, skipping gears, or failing to respond to shift commands.
Fault Code P0919 – Gear Shift Position Control Error
P0919 points to a fault in the system’s ability to verify or control the current gear position. This can occur if the shift position sensor is reading incorrectly, the actuator is not moving as commanded, or the internal gear mechanism is out of alignment. Drivers may experience the car refusing to select any gear, or the vehicle displaying an incorrect gear on the dashboard.
