Help with O2 sensor replacement
 
I've got a 2004 Liberty v6 with a P0139 code...

I think this is one of the back O2 sensors by the exhaust pipe. I'd like to pick up the sensor tomorrow and TRY to replace it myself.

I have no idea what I'm doing aside from what I've managed to learn on google in the past couple hours. Engine light's on and I need to pass inspection :(

Thanks

Stacey

Bank 1sensor 2 front of vehicle, post cat. Use OEM O2's and borrow a O2 wrench from AZ or Orielly's. make sure you get h correct O2 PB as each one is different. Also be sure not to touch or get anything on he new O2 as hat causes issues.
