P0914: Gear Shift Position Circuit OBD-II Trouble Code

An automated manual transmission/semi automatic transmission works like a manual, in that you can change gears faster thanks to the single or dual clutches. When you put the shifter into gear, the gear shift position actuator uses an electric motor to help engage the gear. If the ECU detects a problem on the transmission GSP actuator circuit, a P0914 DTC will be saved.
