2004 prius, p0a80 p3190, red triangle, sell with or without another hv batt?

I'm on the fence about this.
Have a prius 2004 sitting that I need to sell somehow.
Background:
-just over 200k miles
-single owner
-replaced hv batt ~5 yrs ago with a 4-year-warranty greentechauto 'all new cells' batt for $2400+ including labor plus tax
-i haven't checked the hv batt fan, odds are it was never checked or cleaned. : (
- north texas summers are brutally hot especially this summer.
Cronology of symptoms:
1. Driving around, it gives red triangle of death, but no codes at all (obd2 bluetooth). Did 30second 12v batt disconnect, reconnect, triangle gone, still no codes, drives ok, so drive home
2. S o i finally do swap the combination meter that was getting flaky last few months, with brand new oem programmed one. Symptoms = combo meter would stop displaying, but 30s 12v batt disconnect ,and it would reset and show fine again. But soon enough that would get worse so needed to get it done.
3. Next day driving , it dies again, red triangle, this time p0a80 p3190 are both thrown. Towed back to house. Then if cleared codes ,It would only start and produce power for 10 seconds, then rethrow codes with the red triangle. Dr Prius app shows same codes and shows 3 or 4 modules going red with low resistances. Looks like hv batt failure to me, any chance of anything else?

Do I try to sell as-is or put in a hv battery? Ebay had one $600 'reconditioned 1 yr warranty', good option? If it ran it seems would be worth 3k-3.8k or so $. Else what could i sell it for , $1.5-2k max? Harder to sell since buyer wouldn't see it driving. But who likes dumping more $ into a car they have to sell for questionable $.

Maybe i can post the dr prius screenshots with mobile phone

Thanks for all advice people.

 

TMR-jWAp : as for 'engine fails to start', does that apply to the engine actually running the ten seconds and then stopping? wouldn't that be where you never actually hear the engine running , or perhaps turning over but not actually running? It did make the same noise of running that it always has in the past...

And if it is failing to 'start' whatever that means, any tips on diagnosis? or just look through forums on p3190?

thanks

 

Selling it because I was given another car with far fewer miles and would rather use and maintain it than the prius... sad to see it go...

Intersting.
come to think of it the 2 incidents (1 = redtriangle , no codes, 30s reset fixed, and 2 = 10second engine runs then stops with redtri + the 2 codes) came right after a oil change + enginefilter + cabinfilter. I havent checked to see if the oil was over full or if throttle body has something interfering (shouldn't because thats a pretty new throttle body within 2 ish years) and need check mass air flow sensor.

 

Update - today the oil dipstick (engine cold) showed a full inch above the max line. So just now I pumped out maybe .7qt oil and multiple checked dipstick: just under the max line now. Throttle body showing a bit of black stuff on the flipper's edge area on one side - ouch... looking into how to clean with the TB cleaner spray. Pretty sure i can just spray it in there and swap with a toothbrush or so. The TB is new because the lube place couple years ago said it needed it (thrown code, took it in... sigh - probably got ripped off) along with new mass airflow sensor. I have the mini vci obd2-usb cable, it's supposedly the later more expensive version from a China seller but I haven't verified. Need to get the software and a virtual machine going.

Any other ideas on procedure todos before I try to start the car hoping the hv batt has one last attempt in her before she needs actual charging which is gonna be more $ down the drain in a charger?? ugh...

 

Thanks. Yeah got some carb cleaner and MAF specific cleaner at autozone. Haven't used yet. It's sounding like toothbrush or q-swab to carefuly clean TB, not spray a bunch inside it, and tape off the MAF sensor to protect it. Have kept the 12v batt indoors these past couple of cold months. Yeah i should have posted on here a long time ago... SMH. It sounds like even the 12v battery is difficult to charge, I only have one of those older trickle chargers for normal batteries, not sure would help the 12v. 12v right now reads 12.3V, could put in and use a car jumping unit in case it is weak.

SKibob : by plugs do you mean corrosion on connecting bolts (or terminal whichever it is) of each module inside hv batt?

If it doesn't start I'm tempted to buy a batt reconditioner tool...

 

The Prius runs! I took off air filter housing top and bottom, clean throttle body somewhat with some carpet cleaner and toothbrush, it send me clean but there still some of those carb remaining , cleaned MAF with MAF cleaner, put it all back together, gaskets in hoses seem tight I doubt any leak, plug-in battery and it turned on, idle Rough 4 maybe 5 or 7 seconds, then dr. Prius app showing state is 50% charge, a far cry from when it's thought it was very low charge before. so slowly driving down the street I thought it was a little bit slightly Rough, have not cleaned or checked spark plugs yet so I might do that and still more thorough cleaning of throttle body . The intake of the beneath the throttle body seems oily but not a puddle of oil. Also have not used injector cleaner in fuel.

Attached pic of the oil I took out with a cheap orange siphon pump. Afterwards was just barely below Max oil mark. That's a 96oz bottle label shows and ruler so people know precisely how much extra oil there was .
