Code Definition

P0A60 (288) — Drive motor A phase V current sub sensor signal out of range

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

About P0A60

P0A60 is a generic (obd-ii standard) powertrain diagnostic trouble code recorded for Toyota vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0A60 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; and a sensor-related fault — the reported value from the named sensor is out of spec.

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 P0A60 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

On this Toyota hybrid system the phase current sensors for Drive Motor A are integrated into the inverter assembly and report current to the Power Management Control ECU for precise torque control and motor protection. DTC P0A60 sets when the ECU detects that the Phase V sub current sensor signal is outside its calibrated range. This can result from a faulty current sensor, an open, short, or high resistance in the sensor signal or ground wiring, a reference or supply voltage problem, or a genuine phase current imbalance reaching the sensor. When the fault is active the hybrid system may reduc...
