02 sensor 4 95 Civic EX
 

So I know that the o2 sensor is right by the exhaust manifold. My question is how to replace it....if I have the exhaust manifold cover off already is it as easy as just unscrewing it and switching it for a new one?

Thanks,

they make a special tool for it. it's a socket with a slit in it for the wire to go through.

you might be able to use a wrench but its really hard to get leverage in there

. you can get the tool at your autoparts store. and yea, it's basically unscrew it, and put the new one in.

with the wiring harness, you have to take the wiring harness off its bracket, then unplug it.
