The P0922: Gear Shift Forward Actuator Circuit Low indicates that the gear shift forward actuator circuit is experiencing a lower-than-expected voltage. This issue can prevent the actuator from properly engaging forward gears, affecting drivability.
P0922 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P0922: Gear Shift Forward Actuator Circuit Low |
| Is it serious? | Yes, low voltage can prevent proper forward gear engagement, leading to drivability issues. |
| Possible causes | – Low voltage in the gear shift forward actuator circuit – Faulty gear shift forward actuator – Wiring or connector issues |
| How to diagnose? | – Check the circuit for low voltage – Inspect wiring and connectors – Replace the gear shift forward actuator if necessary |
P0922 Meaning
The P0922 code signifies that the gear shift forward actuator circuit is registering low voltage. This could be due to damaged wiring, loose connections, or a malfunctioning forward gear shift actuator. When the actuator is not receiving sufficient voltage, it may be unable to engage forward gears correctly, leading to transmission shifting issues.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for any additional related codes to help identify the issue. | OBD-II Scanner |
| Inspect Wiring and Connectors | Visually inspect the wiring and connectors related to the gear shift forward actuator for signs of damage, corrosion, or loose connections. | Flashlight, Multimeter |
| Check the Circuit for Low Voltage | Use a multimeter to measure the voltage in the gear shift forward actuator circuit and compare it with manufacturer specifications. | Multimeter, Vehicle Manual |
| Test the Gear Shift Forward Actuator | Test the gear shift forward actuator to ensure it is receiving proper voltage and functioning correctly. Replace if necessary. | Diagnostic Tool, Multimeter |
| Replace Faulty Components | Replace any damaged wiring, connectors, or the gear shift forward actuator if needed. | Replacement parts, Tools |
| Clear Code and Test Drive | After repairs, clear the code and take the vehicle for a test drive to ensure the issue is resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | Re-scan the vehicle after the test drive to confirm that the P0922 code does not return. | OBD-II Scanner |
