non camaro ??? i have to replace my wifes 1997 camary oxygen sensor so is it infront of the catalytic converter or down stream and is it a bitch to replace ??? i would figure its straight forward, thanks

When I did this for my daily driver (not a Toyota) I bought a special deep-socket for O2 sensors. It had a slit for the wire... The socket, a long breaker bar, and some penetrating oil did the trick. Mine were not too bad to change.

Piece of cake. Like BM said, they make a socket, but I don't have one. If you snip the wire off the old one a regular socket works. The new one you can usually weasel in with an open end wrench.

I just noticed it says CAMARY. You mean Toyota Camry, not Camaro? A Camaro of that vintage likely has two O2s and two HO2s. All come out the same. Toys prob much the same. Simple devices O2s. I've also had some luck cleaning them and reinstalling.

I'm curious (now that I'm a lot older but not much wiser :confused:) should anti-sieze be used on O2 sensor threads?

yea i meant camry:D

I don't know if the '97 Camry has one or two sensors. '97 is a difficult year for OBDII.
First, it is a 4 cylinder, right? Just want to make sure.
Second, it's probably the front sensor, otherwise you'd probably have been told the cat was bad. Often "bad cat" codes come from bad sensors instead. A good scanner will tell you if it is the front or rear (pre- or post- cat) is bad.
The sensors usually have anti-sieze on them already, so you don't need to worry.

yea its a 4 banger thanks for the info i will try the upstream one first
