Auto parts store cleared codes now :(

First of all hi and thanks for any further help .

so here is how the story goes this is not my car it’s my parents who are in their mid 80’s it needed some strut work so they parked it over the winter . Until I could get time to change out the struts . When I went to work on it the 12 volt battery was dead(2 volts dead). I charged the battery till the battery charge shut [email protected]

I reinstalled the battery started and moved the car to garage and did the strut change everything went fine took it out for a ride around the county block 5 plus miles every was great brought it back parked it in the garage next day my dad went to take the car out it would not start so they took the other car.
When I checked the 12 battery it was dead it showed 11 volt but only 6volts under a load so I took the battery out told they to get a new battery . The dead battery triggered lights on the dash.
My dad installed the new battery and the car ran fine other the the lights on on the dash.They dove the car I would guess about another 50 miles here and there doing this and that ( getting it lined ect ect).
Then they were going to bigger town to do some shopping being my dad the lights bugged him .He stop in a the local town to the big box auto store to have them check for codes which they did and cleared without giving him any kind of printout.
After they cleared them codes the car will not accelerate the car only runs about 6~8 mph it seems to be running on battery power when the gas engine should start the car shutters and just slows down to the 6~8 speed and is only running on the high voltage battery .Which kinda baffles me because when it back it out of the garage the gas engine starts and runs.
I have a cheap obs2 scanner and it only shows to codes P0441&P0445

I found a fairly large hole in the vacuum line to the pcv valve and I’m pretty sure the gas cap is bad..the vacuum line is fixed and a new oem Toyota cap is coming this week. The car has approximately 120k on it
I’ve tried searching the forums for days similar problems with little luck on my part I’m sure its on here somewhere if I only knew what I’m looking for

 

The fix as in the vacuum hose on the purge valve (I know I said pvc but it was the purge valve)and the vacuum hose … the answer is no the gas cap is just now sitting front of me it just came in and I just got home.. I don’t think the gas cap would keep the engine from starting when driving

It’s not that cheap of scanner it should be able to do something it has quite a few functions including live data

to be honest me not fully understanding the full functions is most likely more the issue than the scanner

 

Vacuum hose and gas cap made no difference in the gas motor starting when driving.

rescanned the car 21 module memory (8dts)
Engine and ect (2)
P0441
P0455

Smart key(3)
B2784 antenna coil open/short ( 2 times)
U0155 lost communication with instrument panel cluster
Tire pressure monitor (3)
Transmitter id2 not received
Transmitter Id 4 not received
C2175 vehicle speed or rissi signal error

When I switched to ev mode it said “ ev mode not available “
When I ran the hybrid battery scanner it shows all 14 cells @15.5 or 15.6
Power mode made no difference in trying to accelerate
