My check engine light recently turned on in my 1999 4 cylinder 2.2L Toyota Camry. I took it to the dealership today and they diagnosed that the Bank 1 Sensor 2 O2 sensor needed to be replaced. They wanted to charge me $300 for the fix but the part only costs $120 at autozone. Can some auto sage help me locate and replace this part? Thanks alot in advance.

Ok.  its a 4cylinder, so you tecnically dont have any banks. if you follow your exhasut from the engine (header) down to the cat, you will see two sensors in your pipe.  One before the cat and one after Your secondary sensor is the one furthest from the engine.  The second sensor.  They are generally super easy to replace.  To make it easy on yourself, buy a 02 sensor socket.  Then its just a matter of unscrewing it, uncliping it from the wiring harness and replacing it.  

try this if you just need a little info to get you going.

I erased your other thread because It was a repost.  

Thank you very much automotivejtm. I found the sensor. I was looking at O2 sensors and there is a fairly large price gap. Which one do you recommend? How much more difficult is the installation of a universal sensor and what is a sensor socket? Thanks again.

heres a list of some.  A universal sensor is one that you would have to connect the wires to your wireing harness your self, something you dont want to do if you dont have any mechanical background.  I would say its almost worth the extra money to buy one made specifically for your application.  An o2 sensor socket is a socket (you can pick up at any local parts store) that specifically made to remove o2 sensors, it has a slit on the socket so that the wireing harness wires dont get in the way and the socket can turn around them.  

Thanks alot for all the help, you guys are the best. I will let you know if i run into any problems.

Your fan,

Beware of aftermarket O2 sensors. It's the same ol' story, you get what you pay for. Cheaper ain't always better...... My opinion, spend the money and get the dealer one.  

ughhhh, i got the part today and was trying to install it. first problem, its really hard to unscrew the sensor from the exhaust....im kind of scared to use too much force. second major problem...the cable from the sensor itself runs through a little rubber protector into the interior of the car and i cant locate where the connection is made....if anyone has any suggestions im in desperate need of help and it would be VERY appreciated. Thanks in advance.  

The sensor can be hard to unscrew, dont be scared to use a little force.  As far as the connection running inside your car I would imagine there would be a harness pigtail connector on the outside of your car, how long is the wiring on your new sensor?
