About P0A61

P0A61 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 P0A61 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 P0A61 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

Drive Motor A is a three phase AC traction motor, and the motor control module monitors the current in each phase to keep torque balanced during motoring and regenerative braking. DTC P0A61 sets when the measured current in Phase V is below its calibrated threshold while that phase is commanded to operate. A low reading indicates the current path is restricted, typically by an open or high resistance phase cable, a poor high voltage connection, or an open motor winding, though a current sensor or inverter output fault can produce the same symptom. The driver may notice reduced power, rough or ...
