New prius owner just installed Techstream...Help

Hello everyone!

I'm a new prius owner and bought a low millage 05 prius about a month ago. Drove the car and inspected it and everything looked really clean.

About 2 weeks into ownership I got a check engine light. That prompted me to get a mini VCI cable and look into it. (I DIY pretty much everything I can)

So I finally got it running on my laptop today and I got a slew of error codes. I need some help determining what to do from here. My plan was to clear them and drive it and see what comes back as several of them seem to be historical.

however could someone look it over and see if there is something that is critical?

Hybrid control:
P0A0F
B2799

Engine and ECT:
P0171
P0456
P3193

Abs/vsc/trc:
C1241

EMPS:
U0121

Air conditioner:
B1421

SRS airbag:
B1653
B1655
B1821

Thanks for getting help everyone!

 

The car had a clean carfax and I can't see any indications of previous damage that would have gone unreported.

No other dash lights other than check engine. Came up after a full throttle run up to highway speeds to get in front of a semi.

I've checked the fuel cap and visually inspected the engine bay but am not super familiar. I will try to look up a diagram and investigate further.

I will check the battery. Looos like that could be cause of a couple of the codes.

The car seems to have a small miss at idle when at a light or something before the engine shuts off. Haven't had an oprtunity to troubleshoot. I'll start with inspecting plugs and what not. Millage has been 47-50mpg. The cars gas guage does seem to be pretty far off. It tells me to add fuel after 300-350miles when I'm getting that mileage and a 10gal tank. That may have caused the "run out of gas" code. (I never ran out of gas but did drive to 450miles.)

Will report back on the battery test and what codes pop back up.

Thanks for the quick response!
