P0A60 (289) — Drive motor A phase V current sub sensor signal open

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 an open (broken or disconnected) electrical path in the monitored circuit; 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

This Toyota hybrid system uses both a main and a sub current sensor on each motor phase for redundancy and accuracy, with the sensors integrated into the inverter assembly. DTC P0A60 with this sub code sets when the Power Management Control ECU detects an open circuit in the signal line of the Phase V sub current sensor for Drive Motor A. It is distinguished from a general out of range fault because the ECU specifically sees no valid signal, typically from a broken signal or ground wire, a failed sensor element, or a connector fault. When the fault is active the hybrid system may limit or inhi...
