Code P0924 Description

The P0924 diagnostic trouble code (DTC) indicates a problem with the Gear Shift Reverse Actuator Circuit being open. In vehicles with automatic transmissions, the gear shift actuator is responsible for controlling the movement of the gear shift lever, allowing the driver to select different gears. The reverse actuator specifically enables the selection of the reverse gear. When this circuit is open, it means that there is an interruption in the electrical connection that controls the reverse actuator, preventing the transmission from engaging the reverse gear properly.
