A P0911 trouble code means that the Powertrain Control Module (PCM) has detected a fault with the gate select actuator circuit. Other codes often associated with a P0911 trouble code includes a P0904, P0905, P0906, P0907, P0908, P0909, P0910, P0912, and P0913 trouble code.
The PCM uses the gate select actuator circuit to help when shifting gears while driving. When the actuator fails to work properly, a trouble code is stored and the Check Engine Light illuminates.
The most likely cause of a P0911 trouble code is faulty or damaged wiring and connectors. A bad transmission gate select actuator circuit can also cause the storage of this code, as well as a damaged PCM or Transmission Control Module (TCM).
Some common symptoms of a P0911 trouble code is transmission slippage or a failure to go into a certain gear. In addition, a P0911 trouble code can lead to a reduced fuel efficiency in the vehicle in question.
To diagnose a P0911 trouble code a mechanic needs an advanced scanner, specialized scanner, Control Area Network (CAN) Bus wiring diagram, auxiliary ground cable, and a digital volt/ohm meter. They must also perform the following steps:
A common mistake often made by mechanics when repairing a P0911 trouble code is to overlook a bad gate select actuator switch and repair or replace a component that is not the cause of the problem. The result is the return of the trouble code.
Vehicle owners should have a P0911 trouble code fixed as soon as possible. Otherwise, the vehicle transmission could start slipping or fail to shift into specific gears altogether.
