About P0A35

P0A35 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.

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 P0A35 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 B is one of the traction motors in a hybrid or electric vehicle drive system, and its temperature is monitored by a dedicated thermistor that is commonly integrated into the motor stator windings or the inverter assembly. DTC P0A35 sets when the powertrain or motor control module determines that Drive Motor B temperature has exceeded the maximum calibrated threshold for a defined period. The module relies on this reading to protect the motor from thermal damage, so when the limit is reached it will typically derate power, limit available torque, or command a protective shutdown of ...
