    Hi all - 2007 Prius with a persistent P0A7A. Have replaced inverter and pump. Still getting same code. No other codes. Battery pack voltages look VERY low - any chance the pack is causing the issue? Or the HV ECU?

    Thanks!

    There are 9 different subcodes (INFs) for that thrown DTC.

    Without knowing the supportive INF, it would be difficult to offer advice.

    You may need to source/borrow a Toyota hybrid compatible OBD2 reader to proceed any further with a diagnosis.
