No, that's an O2 sensor code, had the same problems and it was o2s.
Check with Olathe, they are an OEM dealer but I always find the parts here for the same price as autozone stuff

I just bought O2s from them for cheap.
I do NOT feel good about it! I've been keeping up with it for the past few months and I just don't get the warm and fuzzies thinking about technology piloting our cars. It seems inevitable though.
I think they recommend 32 psi, it depends on the tire package. The 2013 models do warn you if the air pressure it too low...
Don't fill it up to the recommended max on the sidewall though.
I just had those codes myself and was searching to see how common they were...
Did you get it worked out?
I did find out that those two codes were Toyota specific so not every mechanic is going to be helpful here...
