changing o2 sensor?

How hard is it to change the o2 sensor?

I kept thinking they were crazy expensive, but I see cb7 DENSO(which i guess is OEM) for less then 60 shipped.


Pretty sure the o2 on my car is the original, although i have no CEL's I'm still thinking replacing it might help gas mileage. IDEAS?

its not hard to change. you can get a o2 senor socket or use a wrench about a 15min job

they sell the socket at ur nearest auto parts store. tell them you need the o2 socket and use it. it'll be a breeze tho.

INFO or a DIY link?

Where is it located?

What do I need to remove?

Since you have an EX its under the car

[Shay91Racer]

ur o2 sensor is located behind your heatshield. you'll have to take it off and then it'll be in plain sight but it might be visible with it on. IDK because mines isnt on anymore. but its on your header.

or where he said.

since you have an EX, i believe yours will be under your car on the downpipe. for me, i didnt even need the O2 socket. i just used a crescent wrench. hopefully yours hasn't seized onto the downpipe.

IDEAS?

Don't replace a working part.

Spend the $60 on personal satisfaction, whatever that means to you. Could be window tinting, a bag of weed, cheap rimjob, whatever.

Peace.

Its the original o2 from 1990.

Just because its not throwing a CEL doesn't mean it isn't lazy.

My timing belt is just fine also until it breaks

yea the o2 sensor is located on the back end of ur downpipe where the 2 pipes become one. most likely on top of the pipe.

my o2 sensor siezed up on me and i just left it alone until i did my motor swap.

o2 sensors arent hard to change at all unless it siezed which u can unplug the o2 sensor, take the downpipe off and soak the o2 sensor in wd40 or pb blaster until u are able to unscrew it.
make sure u let the engine, and exhaust cool down
