P0913

Gate Select Actuator Circuit High

Severity: High
Driving: Drive only to a garage

The gate select actuator circuit is reading high - typically shorted to voltage or a lost earth. The module cannot drive the actuator, so the selector shaft will not move across the gate and gear changes will fail.

Possible causes

CommonWiring shorted to voltage or a lost earth between the module and the actuator
CommonCorroded or water-ingressed connector at the gearbox
CommonOpen or shorted actuator winding
PossibleChafed harness at the gearbox
RareFailed control module driver

What you might notice

Transmission will not select gears
Car stuck in neutral
Transmission warning message
Check engine light on

What to check, in order

Disconnect the actuator and check whether the high reading persists at the harness.
Inspect the connector for corrosion and water.
Measure the actuator winding against specification.
Follow the harness looking for chafe damage at the gearbox.
Run the calibration procedure after any repair.
