What this code means

Gear Shift Position Circuit High.

P0917 is a generic code: it means the same thing on every make. P0917 belongs to family P09xx — Transmission and controls. Its page explains how to read a code and groups all its codes by part.

Type of fault

The control unit reads a voltage on this circuit above its expected range. Usual causes: a broken wire or a poor ground, a short to a supply voltage, or the component itself. As with a low signal, check the wiring and connector before the part.

Automated gearbox actuators

Automated manual gearboxes are manual gearboxes whose clutch and gear changes are operated by actuators, hydraulic or electric. Sensors measure the clutch position and the selector position, and the control unit learns these positions.

What you notice

Jerky starts, a slipping clutch, a gear that will not engage, a gearbox stuck in neutral.

How to check it

Check the hydraulic fluid level if the system uses one, the actuators' connectors and the battery voltage, since these gearboxes are sensitive to it. After any repair or a battery disconnection, a relearn of the positions with a suitable tool is often required.

What to do

Have it checked this week. The car remains usable, but the fault will not clear itself and will fail the roadworthiness test.

Clearing a code switches the light off but repairs nothing: if the fault remains, the code comes back. Clearing a fault code yourself →
