I don't know if anybody has changed, but since I think I have twisted the wires putting on eliminator, I have to change it....so does anybody know how to take off the second o2 sensor, any advice would help!!!

 

you just gotta get under your car and undo it from the pipe then undo the clip on the wiring harness right above it. You put an eliminator on it, so Im not exactly sure what your asking here.

 

I think he means taking it off from the actual car...I don't even know how to do that

 

the 2nd one i think is connected right before the catalytic converter...it's a pain.....

 

My point was that he said he had installed the 02 sensor cel eliminator. You have to pull off the 02 sensor to get that on. So I dont rightly know what exactly he is asking. Hes already had to of removed it once.

 

Right, but I think he's talking to the wiring that connects to the actual vehicle. I'm sure anyone and everyone knows how to unscrew something.

 

I'm not exactly sure on a Lancer as I've never changed one of these personally, but if it is anything like the Evo's 2nd sensor the connector is inside the car underneath of the passengers seat and I believe you have to take the seat out and pull up the carpet to get to it unless you can manage to pull the connector through the grommet hole. Idk if this will be any help or not, but figured I'd add my .02

 

^this, its the same thing but i believe ares in under the passenger side dash near the center console under the left side carpet near it

its really simple just remove the piece that attaches to the center console and move the carpet back and the o2 sensor right there, u can even do this from under the car just pull on the plug that the o2 goes too and just unplug it

 

Youd be surprised.
