I destroyed my 2008 Prius, need help

Welcome to PriusChat!!

Your "Location" mentions Ca, how close are you to a major metroplex, as there may be a member who could assist.

Here is the diagnostic workup for DTCs P3190, P3191, P3193 :

If you've had a low 12v situation, or have disconnected the 12v recently, then you should also clean the MAF sensor and disconnect it before attemptiong to restart the engine, if the engine starts and after it has charged up the HV battery then you can reconnect. If the above doesn't get the engine going, then go through the posted workup (above) for DTC P3193 step-by-step and report back in this thread.

Realize the disconnecting the 12v will reset the HV battery to a false state of charge (SOC), making it appear to be half full again.

You may need to borrow, buy, or build a 'grid charger' to recharge the depleted HV battery if the engine won't start.

You may want to buy a 'mini-vci' cable and use 'techstream' (dealer technician diagnostic software) to retrieve those obd2 codes.

 

Have you actually tried adding fuel? At least 3-4 gallons?

 

Also might want to clean the throttle body. If the 12V battery went low enough or was disconnected then the ECM would lose its "learned adaptation" for correct throttle opening.

Keep in mind that when there are error codes and the warning lights come up on the dashboard, it's because the car's computer thinks something is wrong. Clearing the codes doesn't fix anything; it really just makes you lose information. The proper thing to do is find out what error codes are saved in the computer, find out what they mean, fix the problem, and only then reset the relevant codes.

You said that everything was fine before, but it wasn't because there were errors. If you're able to retrieve the error codes now, that would help figure out what needs to be done at this point.
