P0A60 (294) — Drive motor A phase V current main and sub sensor signal error

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 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 monitors Phase V of Drive Motor A with both a main and a sub current sensor, and the Power Management Control ECU continuously cross checks the two for consistency. DTC P0A60 with this sub code sets when the ECU detects a discrepancy or a simultaneous fault between the two sensor signals, such as mismatched values, both readings out of range together, or implausible signal patterns. Because both sensors are affected, the cause is often a shared supply, ground, connector, or wiring fault, a genuine Phase V current imbalance that both sensors report, a failed integrated...
