2012 Prius c PA080 no Inverter Pump Flow

There's a lot less to find for Prius c. Whether that's because there are that many fewer of them, they don't break as often, none have broken yet or something else has caused breakdown & resolution stories to be scarce, I couldn't say.

You need a different reader for the INFormation sub-codes. Autel AP200 highly recommended. I have the AP2500E, that also does them. I'm not aware of anything you can do to get torque/dr.prius to read these.

Here's the thing: there is only one sub-code for P0A80, "123" and it means the computer is convinced your battery is dying. Not really worth buying a new reader just for that.

Is there something leading you to think there is an inverter problem? I can't see your car but so far this looks simple: needs hybrid battery.

 

Don't bet the farm on me, but I'd expect it to work more like a gen 3: variable speed pump that runs under the control of the power management control ECU and only when needed. The gen 2 pump runs at a fixed speed and whenever the car is ON.

Yeah, there aren't really any lights on the dash that mean "12V problem", with the exception of this one:



Of course, the lights generally indicate you should read trouble codes, and when you do that, sometimes there will be codes that suggest a 12V problem (when you look those codes up, their detection conditions will say something about a measurement of power supply voltage falling below a threshold, usually around 8.9 to 9.5 volts).

Seeing the battery-worn-out code and no other code would generally be a strong indication the battery is worn out and there isn't some other problem. But with Dr. Prius I wouldn't quite make a final conclusion that there aren't other codes; Dr. P is known for only showing certain "engine codes" and "battery codes" and not much else.

A second opinion using a scan tool known to retrieve all trouble codes from a Prius might be worthwhile.
