Another dreaded P0A80 + P3013 error

I have a 2006 with 99600 miles. It has had a bad TPMS for about 4 months (probably totally unrelated, but I know it can send errors to the VSC, and the ECMs all chatter to each other). This summer I got the Master Service Warning, plus VSC, (!), and check engine lights. Had the P0A80 code when I checked. Cleared it and it seemed fine (other than the TPMS error).

It got cold recently, and the same warnings went off. I thought maybe just the same problem. I cleared the codes just to make sure, and they came back this time. Was going to take it in today, but got called into work early. Cleared the codes just on a hope and a prayer that it would be fine and I could deal with it Monday. Nope. Now the fan for the battery vent is running. I have the following codes: P0A80, P3013, C2300, C2318, C2124. The last is the TPMS. The P3013 is block 3 of the hybrid battery (sheds big tears), and the other two C codes are transmission codes (I assume related to the VSC not operating properly because of the other electrical issues?)

Having looked through the other threads, it looks like it is a hybrid battery replacement (or buy a car). It is obviously otherwise low mileage, has new break pads, the 90K service/maintenance a year ago.

Questions: (1) is there anything that I should try to have repaired or replaced to rule out before going to the hybrid battery (I've seen corroded connectors, 12v battery, hybrid battery fan mentioned in some other threads, and just want to make sure there might not be a cheaper fix to rule out)? (2) I'm not planning to keep the car for 8-10 more years but I'm also not going to go the reconditioned battery mode or replacing a single block given the track record being that this is either a short term fix of crap shoot, so any thoughts on the replace the battery vs seeing if a dealer will give me anything towards a new or slightly used Prius?

Thanks!

 

Thanks. Sort of, and sort of not: divorced & she got the V. Guess I should update that

Now that it is my main driver, it is getting more than 8K a year, but for a while I could walk to work, and we always took the V if it was available. Now, I have a commute & no V.

 

I'll probably look to buy something used. I'm wondering if I can get anything for mine with a bad battery? The battery core recycling should be at least worth something

Nothing close to the cost of replacing the battery. There is a '07 Prius with 9k more miles, for $6k, and I doubt it has a new battery.

Maybe just get mine fixed, then detailed, and pretend it is a new purchase...

 

Thanks, but got it fixed. $2,600 at the dealer was better than I expected from other posts.
