Is my 2001 a wierd model? All o2 upstream sensors come with a different pin configuration than mine has. Plug facing at you, I have 2 wide right, two close on top and one opposite side nothing on the bottom. Every part I look up has 2 and 2,and two. It's a 2.2 engine, 01 Camry. I do have 15 inch tires and some have 14s. thank you for any help.

replace the vsv that has the vacuuum hose running from it to the egr valve
SOURCE: i have my check engine light on and a p0031 error
On toyotas this is almost always a failed o2 period. Take it somewhere and have it put in. On v6's it is not that easy to get to.

yes an o2 sensor can cause those symptoms so can a minor vacuum leak --bad ignition wire -clogging fuel filter --sticking egr valve etc.

An O2 sensor code is a tricky one. It could mean SEVERAL different things, and I know how bad it sucks to hear this, but your best bet is to take it in and have a diagnostic ran on it at either a dealer or a good mechanic shop with a computer they can hook up to it. I had an "O2" code come up a while back on another car I used to have, and literally spent weeks and hundreds of dollars trying to fix it, and never did. Finally out of desperation took it in, paid the $90, and they found the problem and fixed it in like 30 minutes. Something I would have never even thought of was causing it (can't remember off the top of my head). After that I stopped wating time and money on check engine lights. One comes on in my car, I take it to have it ran for free at and auto parts store just to make sure it's not a loose gas cap or something, just to get an idea of what I'm looking at, then go and make an appointment to have to hooked up to a diagnostic computer to track down the problem. Good luck, and hope this helps save you some time and money.
