How screwed am I

With only 108k on the clock, that car has a LOT of life remaining in it.

My general thought is that anyone who keeps an OBD2 reader in the car is most likely capable of repairing their own HV battery with just a bit of guidance..

The other 2 codes are being misread by your generic code reader

1121 and 1150 are codes for the hot water storage tank system

This is why it's extremely important to use a reader capable of interpreting hybrid info. You could go on a horrible goose chase.

Take a look at this thread, it shows the same lights for the HV battery issue.

Can we add another option to your survey? Option 3 could be "Buy a new car and give old junker 2006 Prius to TMR-JWAP"

 

Welcome to Prius Chat .

If you are mechanically inclined and want to keep your Prius alive, I’d repair it.

But if you want to use this as an opportunity to move on, that’s another option.

Only you can answer how badly you either want to repair or replace your Prius. Good luck and keep us posted .

 

1121 is the Coolant Control Flow valve position sensor circuit stuck.
1150 is Coolant Path clog for coolant storage tank

Both of these together typically mean the valve that controls flow from the tank is stuck/failed. No big deal.

Your reader is mislabeling the codes, except for the P0A80, that is correct, That one means replace the HV battery

 

The transmission is attached to the electric motor / battery, so if your battery is dying, I assume you'll be grounded very soon.

 

The 12v system is used to power up all the electronic systems, lights, ecu's etc. It's kind of like turning on your computer before you can actually use it.

The HV battery is like the hard drive. The car will be severely handicapped with the HV battery out of commission. If this was the first time you've had that HV code, you're likely in the early stages of battery failure. Many times, an owner can keep a code reader available for resetting the codes and it will allow you to keep using the car (carefully), but the code will start occurring more and more often, eventually leading to the car going into limp mode. Also potentially creating additional damage to the battery. At some point down the road, the car will no longer go 'ready'. Some people have gone many months doing this. It's easy to say what's the right or wrong thing to do, but everyone's situation is different and there's a LOT of gray area in the world..

 

You can get a kit of new cells for 1600 delivered which basically gives the car a new battery they are so,d by @2k1Toaster here and the link is in my signature.

 

The short sensible answer is NO.

See the link in my signature to see what I did when my 06 HV battery died years ago.

 

You do have a decision to make but consider this. 108k is low miles for a 2006 Prius. If the only expensive problem you're having with the car at 108k miles is the 12 year old hybrid battery pack the odds are very high at that mileage you're not facing much in the way of anything else majorly expensive failing on the car in the near future. A new battery pack will give you another 10-12 years for that $2,000. Are you realistically going to find another car that will give you the proven dependability and economy of what you have sitting in your driveway right now for under $4,000 (2006 Prius value + cost of hybrid battery pack)? Remember, too, that your Prius will fetch an even lower price because it IS having a battery issue. Any prospective buyer (or dealer on trade-in) is going to want allowances knowing THEY will have to replace the pack.

Here is the new battery kit. @2k1Toaster is very responsive to questions or concerns.

New Prius Battery Kit (GEN2, 2004-2009) - New Prius Batteries LLC

 

I had my car fixed using the above mentioned battery kit. Protect yourself from high voltage, and it's a 3-5 hours assemble work.

 

Yes.

Best way to avoid running out is to check the dipstick frequently .

Good luck and keep us posted .

 

Not screwed at all cause it's the most overrated repair in the history of cars.

My Prius mechanic will rebuild the bad cells for $400.

Or it takes about 40 minutes to remove battery and 40 minutes to install a different battery. So you get a used one on car-part.com for around $500 and pay an hour or 2 of labor.

If you are in love with the car and are 100% certain you'll have it in the year 2030 then you may want to get brand new OEM. It's about $1700 for part and anyone that charges over $300 to put in is ripping you off....so brand new about $2000.

 

You can clear the code and it will drive fine. I actually drove about 7k miles just by deleting the code (didn't come back for months!).

But if you plan on rebuilding the battery it isn't healthy to do this.

With the code on --- it will eventually lack power....with code off for whatever reason it drives like nothing is wrong with the car lol.

 

That is only recommended if you get a battery pack from a low mile junker. Otherwise you are just putting in an old, repaired battery pack, hoping somebody spent the care & time to do it properly.
