• Causes
• Solutions

The P0923 fault code indicates an issue with the Gear Shift Forward Actuator Circuit being high. This means that there is an electrical problem within the actuator circuit that affects the vehicle's ability to shift gears properly. If this fault code is triggered, it can lead to difficulties in changing gears or inefficient transmission performance.

What are the symptoms of the P0923 code?

Common symptoms associated with the P0923 code may include:

• Transmission not shifting into gear as intended.
• Erratic or delayed shifting behavior.
• Transmission warning light illuminated on the dashboard.
• Poor acceleration or driving performance.

What causes the P0923 code?

Several factors could lead to the P0923 code being set, such as:

• A short circuit in the wiring harness of the gear shift actuator.
• Faulty gear shift actuator itself.
• Poor electrical connections or corrosion in connectors.
• Issues with the powertrain control module (PCM) affecting the actuator circuit.

How to fix P0923?

To resolve the P0923 code, consider the following steps:

• Inspect the wiring and connectors for any visible damage or corrosion.
• Test the gear shift actuator for proper functionality.
• Check for any additional trouble codes that may provide more context to the issue.
• Reset the fault codes and perform a test drive to see if the issue reoccurs.
• If necessary, replace any damaged components or the gear shift actuator.
