Long list of codes

You've really only got a traction battery issue and a couple tire pressure monitor issues.

B1421 only means the car wasn't in strong sun when you pulled the codes. That "trouble" code only exists so you can tell if the solar sensor works: in the sun, no code, out of sun, code.

P0A80 means there's a traction battery issue. P3018 is just saying where in the battery. P3000 is just the HV control ECU in the car saying "I hear there's a battery issue". C1259 and C1310 are the brake/skid ECU saying "heard from the HV control ECU there's some kind of issue."

And the C2123 and C2124 are tire pressure monitor codes. Seems like two of your tire pressure transmitters haven't been heard from lately.

 

The gas gauge fix is a few hundred at best. The hybrid battery in this model someone just needs to look under the hood in the back of the battery and see the corrosion the bus bar blackening and whatever's going on and come up with a plan to fix it if somebody doesn't want to put a new battery. A new battery is the way to go a refurbished battery if you have to. Something or do nothing and start all over again I possibly with another car but it will need similar very quickly too You're just at that point in the cars life and time. Of course good luck

 

they've been out a few years, and so far so good in most cases.

have you called around to dealers for competitive pricing?

 

highly rated doesn't always mean lowest prices, but sometimes price is more regional. some people have been able to find them around $2,000.

 

the only problem with the $1,600. one has been supply and communication. read through the thread comments and keep your eyes open.
replacing modules can work, but is often a short term solution

 

You're in the southeast United States along with me I'm in North Carolina highest rated Toyota dealer in Georgia yeah okay I can't go for that where are you in Fulton county? You need to get in touch with the hybrid doctor up in Fairfax Virginia He can hook you up for around 700 bucks and do a bang up job doing it too He does not play in South American and a good guy He did my generation 3 battery and my wife's been beating the hell out of the car ever since it got put in I think it was around 7:50 or something for a balanced rack of modules and we have had no problems and the person driving the car is not a car person at all in any degree. So look into the hybrid doctor give him a call He might can make a run up there or meet him halfway or something I don't know if you have somebody in your corner that can change out the battery things like that kind of like doing a golf cart if you will That's the best way I can equate it for the area you're in.

 

You're closer to Atlanta than Fulton county Fulton county is Atlant I believe. Or it was when I lived at fort McPherson in the '70s and early '80s. I do not know what happened to the new south big city since then but I think Fulton county has you covered The hybrid doctor will meet people in the south a lot he'll send a driver down to say upper North Carolina in places like that to meet people You have to talk to them and see what they can do He also sells on eBay racks of modules balance to within three Delta for like $700 That's a reasonable deal I think.

 

There should be some franchise folks in your area green tech green bean etc I try to stay away from that as much as possible but if I guess I had no other choice or my other choice would be to rebuild my battery in my driveway but you know I replace d cells in my mag light I'm assuming I'm going to put a new battery in my Prius of some sort rebuilt is the last measure that means I'm either looking to get rid of the car in short order or something else is going on who buys used batteries as far as I know nobody that's the point the batteries expired.

 

A shop that can really do this well we'll have about $30,000 worth of equipment in the shop of electrical equipment testing equipment charging equipment All of that stuff that stuff can also be used on electric cars and other electric vehicle type things like you see on corporate campuses and stuff All of these things are very similar somewhat to a golf cart You have a bunch of batteries wired together to make a certain voltage to run an electric motor to propel you down the course or whatever very similar the chemical makeup of all the batteries whether they're lithium ion or nickel metal hydride or lead acid liquid really isn't so much a thing it's how they're wired the voltage they're going to produce when they're all wired together etc The Prius is like a 211 volt system so people doing this in their garage and what have you are generally playing what people like to refer to as a game of whack-a-mole and I don't know if I would pay $12 $1,300 to play that game The place that I'm talking about will do it for you for about seven or eight and send you the modules to your door You might want to look him up talk to him He's a nice guy he'll talk on the phone.

 

You know you can buy a brand new Toyota battery for $1635 to $1950 from a dealer, don't you? You might need to shop around a few dealers to get them and of course that is a DIY install. I don't think the prices you're quoting are very attractive for a used second-hand battery.

 

Pinging @TMR-JWAP as this could be within range
