Error Code at Autozone: P3190 - Engine Does Not Start

Hello, after having NON-DEALERSHIP maintenance done about 2 weeks ago; I have been having this issue. The maintenance that was done was replacing my brake drums and shoes on the rear wheels. I did not have this code before but I did have P0420 - Catalyst Efficiency Below Normal (Bank 1). Which means my Catalytic Converter is below it's desired efficiency target, not a huge deal for my state.

However, the car works, remarkably well actually. I do feel like I notice a slight difference in throttling which seems to align with this article 2001-2009 Prius P3191, P3190, P0A0F - easy checks for these common codes I haven't tested the 12v battery but I just got back to my town from a >1700 mile round-trip vacation, with some of the BEST performance I've seen in terms of MPG...in months. So all of this is perplexing, because my dash is full of critical errors, which is why I had it checked, but my car is performing better than my average. I think I'll check the status of the 12v battery. I just thought of all this again and am just doing the research at the time of posting this; recommendations and thoughts are appreciated. I haven't had the money or time since the maintenance to go to my Dealership

 

It turns out it’s probably my front right wheel bearing? I took it back to the same shop that replaced the rear assembly and that’s what they said it was. My dashboard has had like every error and maintence light on it and the right front break has been squealing on tight turns and humming at mid-high speeds. It feels like it’s grinding and not moving as freely on that side.

 

Sorry for my delayed response. I checked the 12V and it’s fine; that error code is just what I got from Autozone, I’m not sure of it’s cause. I do believe that my wheel bearing is causing the bulk of the issues and the car does start so I’m not sure what the code was for.

However it’s also possible that during the brake maintenance , something was broken, unintentionally or not; I kind of don’t know whether or not I should trust this particular shop.

 

About 290,000 and not that I’ve noticed.

 

Well I didn’t use a meter on it but unplugging it and plugging it back in didn’t clear any dash lights. I’m going to my dealership tomorrow and I can have them check the codes and get their actual info, not autozone’s.

 

I appreciate all the responses. Thanks everyone.
