P0930 — Gear Shift Lock Solenoid Circuit Low

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

About P0930

P0930 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 P0930 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 P0930 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 P0930 fault code is set when the control module detects a low voltage condition in the gear shift lock solenoid circuit. This circuit controls the solenoid responsible for locking the gear shift mechanism, a key safety feature to prevent unintentional gear shifts, such as shifting out of park without pressing the brake pedal. A low voltage condition in this circuit can indicate an electrical problem, like a partial short to ground, decreased voltage supply, or an issue within the solenoid itself. This condition may lead to inadequate operation of the gear shift lock mechanism, potentially ...
