About P0926

P0926 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 P0926 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 P0926 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 P0926 fault code is set when the control module detects a low voltage condition in the gear shift reverse actuator circuit. This circuit plays a critical role in controlling the reverse gear mechanism, typically involving the even-numbered gears (2, 4, 6). A low voltage in this circuit suggests an electrical problem, such as a potential short circuit to ground, reduced voltage supply, or a fault within the actuator itself. Such a condition can lead to inadequate actuation of the gear shift mechanism, possibly resulting in difficulty engaging or maintaining the vehicle in reverse gear.
