To engage the gears you have selected with the gear lever, the gear selection actuator sends data from multiple sensors to the ECU, which then activates an electric motor to engage the gear. If there is an abnormally high voltage signal on the gear selection actuator circuit, a DTC P0913 will be recorded.
