2009 Prius Cat Converter Replaced, P0A80 Code

Well you're in California so having catalytic converters and all that stuff in place is mandatory unlike where I am your battery block voltage if that's the reading and that's what's going on the voltage being low could be because the bus bars on that blocker dirty black the nuts are frosted with like the white stuff that grows on old car 12 volt battery terminals It's a living organism keep your car from starting lots of times that can happen in your HV battery pack and that can wreak havoc on how that assembly works Toyota will not look inside of that battery pack they just replaced the $3,000 battery pack when someone's at their house and their driveway you will see pictures here of what people see when they look in their HV battery pack It can be quite ugly Just cleaning up the copper bus bars the nuts and a rock tumbler with the proper abrasive and making sure everything is clean and no modules are leaking on the lower tray and so on can go a long way If money's that tight you may not want to be looking at a 3,000 or $4,000 new Toyota battery get a rebuilt It sounds like you're inching your way out of this car very slowly because of age looks whatever the problem may be I can't see from here The car is a good car generally a generation 2 will carry you to $500,000 pretty easily of course you'll be replacing tires 12 volt batteries and consumable things like any other car If you go 600,000 mi with it you'll replace a few of those things more than you will on a car that only makes $150,000 mi obviously so you have to weigh out what you have going on I have four of these cars three of them have rebuilt batteries in them and have been doing very well One of them has a brand new battery from about 2 years ago that I put in so there are lots of variables I don't pay but $700 to a thousand bucks for one of these cars generally and usually they're in pretty nice shape leather interior so on I don't buy any cloth so there's always that but you know driving a car like this to 600,000 means you're sitting in a 16-year-old car until it's like 24 years old to make that kind of mileage and well people look at you funny and all kinds of things so peer pressure can have a lot to do with changing cars and refrigerators and appliances and things like that just depends where you are in the game
