How do you replace o2 sensor?

[DopenessFool]

okay so i got a 93 Integra LS and am trying to replace the oxygen sensor on my own.
can someone give me steps and directions on how to change it?
oh and is there also two sensors or one in a 93?

one= OBD1 2= obd2

So you can get an o2 sensor socket and use that, just put some WD40 on it and try unbolt it.... I have heard You can heat it up with a torch and try remove it that way but I have never done that. Its pretty easy most times...

well is there two or one o2 sensors on a 93?

you should only have one since your car was made before the introduction of ODBII in 96. all you need to do is unscrew the old one from your catalytic converter unclip it and put a new one in reversing the steps. the hardest part will probably be breaking the old one loose.

thanks man.
and would a 90 or 91 integra o2 sensor work?
cause i heard those are single wired and mine might be 4 wired?

No you can not use the OBD0 sensor, stick with the 4 wire sensor.

Id check the condition of your cat too while your down there. my sensors went bad and when i went to replace them i noticed my cat was fucked too.

Here's a pic on a stock header.
It's just a plug.

Unscrew your old one. Put antiseize on the new one's thread and reinstall. Plug it in to the wire.

see #6... that plug. It's really simple. Just take a look and get an idea

you can go without a functioning one but your car will get terrible gas mileage and drive like it wants to die. trust me. its not a good time.

you may as well just take the heat shield off and do it. they hug pretty close to the header.

There is a O2 sensor socket, you can rent them from most stores.
