Need a guide for replacing my O2 sensors

[tido5000]

I pulled my codes the other day, and it's pretty clear that I need to replace my O2 sensors. I've been unable to find any threads on here that detail the removal/installation process, and my SHO repair guide is absolutely useless. I drive a '95 ATX. If it isn't too much trouble, could somebody please give me a detailed explanation (for someone who is by no means a mechanic), or point me in the right direction?

Thanks,
Max

Do a search J/K

Safely jack the car up. Unplug the O2 sensor that is located on your Y-pipe right below your exhaust manifold (it's the silver thing with a wire sticking out where the exhaust is closest to the motor). Then with your 02 socket on a ratchet loosen the old 02 sensor. Replace both and plug them back in. Don't over tighten them but make sure that they are snug

The rear O2 can be tricky, i believe i used a combination of universal joints and extensions to remove it. And, do yourself a favor, make sure your car's not completely warmed up before you do this...it's hot down there, and easy for knuckles to hit trans pan

for the atx rear o2 sensor. went to auto zone and rented the set of sensor tools. the rear sensor is abittch to do the crow foot wrench in set is the easyest to do it with .also you need really small hands to plug in the rear sensor .....

my mech cut a slice in an old closed ended wrench and used that to get them off...

Front is super easy.

For the rear I just layed on top of the engine with my heads toward the firewall and snaked my arms down there. 21 mm wrench if I recall right.

Don't let others fool you. Its extremely easy once you figure out the trick to access to the rear. Unfortunately if you don't you'll struggle for a while.

I’ve always just used an adjustable wrench on the 02's on the SHO. Although I did have to get a socket from my gf's civic since the hex part is recessed under a heat shield.

Is it the same deal for the MTX? Rear hard to access and all? Or is that just the ATX?

MTX is a cake walk. TONs of room from below.

ATX front is easy. Rear requires a small amount of thinking how to contort yourself. Some have had luck using an O2 socket, u-joint and tons of extensions.

I myself just use a 21 mm wrench and lay on top of the engine.
