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

On this Toyota hybrid system the Phase V main current sensor is integrated into the inverter assembly and provides the Power Management Control ECU with real time current data for motor control and inverter protection, backed up by a separate sub sensor. DTC P0A60 with this sub code sets when the ECU detects an open circuit in the main current sensor signal line for Phase V of Drive Motor A. The usual causes are a disconnected or broken signal or ground wire, a failed sensor element, or a connector fault that prevents a valid signal reaching the ECU. With the main feedback lost the ECU may red...
