P0922 — Gear Shift Foward Actuator Circuit Low

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Generic

About P0922

P0922 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0922 is stored, the module has detected a signal or supply voltage lower than the expected operating range.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0922 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The P0922 fault code is set when the control module detects a low voltage condition in the gear shift forward actuator circuit. This circuit is integral to the operation of shifting into forward gears, especially the odd-numbered gears (1, 3, 5). A low voltage condition in this circuit suggests an electrical issue, such as a partial short circuit, a reduction in voltage supply, or a fault within the actuator itself. This condition can lead to insufficient actuation of the gear shift mechanism, potentially causing difficulty in engaging or maintaining the vehicle in the appropriate forward gear...
