P0922 Gear Shift Forward Actuator Circuit Low

OBD2 Code: P0922

Description: Gear Shift Forward Actuator Circuit Low

Definition: This code indicates that there is a low voltage condition detected in the gear shift forward actuator circuit. The powertrain control module (PCM) or transmission control module (TCM) has identified an issue with the electrical circuit responsible for controlling the forward gear shift actuator, which may affect the vehicle’s ability to shift gears properly.

p0922 – Gear Shift Forward Actuator Circuit Low

Typical Severity: Moderate

Common Causes

P0922 – Gear Shift Forward Actuator Circuit Low

Common causes:

• Faulty gear shift forward actuator
• Short circuit or open circuit in the wiring harness
• Loose or poor connection at the gear shift forward actuator connector
• Corrosion in the electrical connections related to the gear shift forward actuator circuit
• Defective transmission control module (TCM)

 

Common Misdiagnosis

OBD2 Code: P0922

Description: Gear Shift Forward Actuator Circuit Low

Common Misdiagnosis: Replacing the gear shift actuator without checking for wiring issues or poor electrical connections.

 

Common Diagnostic Steps

OBD2 Code: P0922

Description: Gear Shift Forward Actuator Circuit Low

• Check the vehicle’s battery voltage and ensure it is fully charged.
• Inspect the wiring and connectors related to the gear shift forward actuator for any signs of damage, corrosion, or disconnection.
• Test the gear shift forward actuator using a multimeter to verify if it is functioning properly.
• Examine the transmission control module (TCM) for any faults or issues that may affect communication with the actuator.
• Verify that there are no other related trouble codes present that could indicate a broader issue within the transmission system.
• If necessary, replace any faulty components identified during diagnostics such as damaged wires, connectors, or a malfunctioning actuator.
• Clear the code from the OBD2 system and perform a test drive to ensure that the issue has been resolved and does not reoccur.
