Alright... need to replace the 02 sensor. So, I bought the o2 removal socket and got it pulled out, but I spent a half hour and cannot get the harness to disconnect!

any hints??

 

Is there a lot of dirt around the plug?

This might make it a little harder to remove. Try some WD40 to clean it up and help get it apart. Carefull with the locking tabs, they get brittle with age.

 

Go ahead and break the tabs if you have to... Simply get a small zip-tie and pull the connectors together afterwards if they break... We do this at the dealer often with old crusty connectors... Use Dialectic grease on the connector before putting it back together...

 

not a lot of dirt... it just won't come apart... i used a flat-head and it is like just stuck or something I didn't know if there is a way to undue the clips...

 

There should be a rubber grommet inside the clip as well... Try prying the connectors open a bit and spray some WD-40 or whatever down in there... The rubber usually just gets hot and bakes itself to the plastic housing...

 

kk ya i'll try that and see what i can come up with thanks

 

is this that grease? it doesn't say the ingredients... and google doesn't turn anything up...

 

Nahh, that stuff will work in a pinch though...

The stuff you want hangs on the same shelf at the local Advance or whatnot... You want "Electrical Connector" grease...

 

That's funny, my buddy and I struggled for like a half hour trying to get the harness on his RSX to come off. The only suggestion I have is to use a flat bladed screwdriver if you can. Whatever you do, don't pull on the wires, pull on the plug.

 

ok... i'll stop back and get that too... i just had this for the o2 sensor when I get the new one hooked up

Thanks! I'm going to keep trying with the flat-head and hopefully it will come off before it's too dark to wire up the new o2 or else i'll be stuck at work definitely don't want to pull out the wires! that would suck... have to hard wire it right to the harness.. not a big fan of direct harness wiring

 

Other opinions welcome about this...but maybe placing it into an oven @200F then try to break 'um apart?

 

it's still on the car

 

alright ended up getting it off with a flat-head and some force they really need to make these easier to come apart!

Thanks for the help guys

 

You mean, your oven isn't big enough? LOL Glad to hear it came apart finally...don't forget the "electrical" grease for the future.

 

He could start the car and yank the harness close to the exhaust pipe.

Glad to hear everything went OK, Dave!
