i need to disconnect the O2 sensor on the exhaust manifold of my 92 accord. i have been screwing around with it for half an hour and i cant figure it out. its also just hard to get a good look at the other side of the connector so if i could get a picture of it that would be great!

haynes manual says to replace the O2 sensor i need to "carefully disconnect the electrical connector from the sensor". well no ****. as usual the haynes manual doesnt help at all

not really sure what your asking here bro, but they sell a o2 sensor remover at autozone for like $6 its the best way to remove them and not damage them... when reinstalling make sure you put some type of a sealer on it so there's no leaks hope I helped..

are you trying to disconnect the electrical connector? sounds like it.

You can use a small flat tip screwdriver to separate the connector while holding the tab which unlocks the electrical connector from it's source. You can use wd-40 to lubricate things if they won't separate.

​​​​​​That's likely because you are releasing one of the two clips needed to disconnect the sensor. You have to unbolt the mounting bracket that holds the connector. Next, insert a small flat blade screw driver under the bracket to release the connector pair from the bracket. Now you'll be able to rotate the disconnect pair around and you'll see that there are two release clips, one verticalaand one horizontal. The horizontal one was locked by the mounting bracket, but now free.

Note: I found it helpful to use a small vise grip to hold one down while I used two hands to release the other and pull apart.
