P0925 — Gear Shift Reverse Actuator Circuit Range/Performance

About P0925

P0925 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 P0925 is stored, the module has detected a plausibility fault — the measured value is in the electrical range but is not consistent with expected operating behaviour.

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 P0925 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 P0925 fault code is activated when the control module identifies a range or performance issue in the gear shift reverse actuator circuit. This circuit is responsible for the actuation of the gear shift mechanism for reverse movement, typically involving even-numbered gears (2, 4, 6). The range or performance issue typically indicates that the operation of the circuit is either falling outside the normal parameters established by the manufacturer or is not performing effectively. This could be due to a malfunctioning gear shift reverse actuator, issues in the electrical connections, or prob...
