Here's a how-to about replacing my O2 Sensor BANK 1 (Passenger side) Sensor location 2 (POST cat). The time needed; 1 hour (can be much faster if you are experienced):

  • The tools I used:
  • LIFT
  • Size 22 wrenche
  • Ductape
  • 4 tyraps
  • Knife or scissor
  • Welding wire


1) Lift the car up in the air, and get a long piece of welding wire (70CM), try to push it towards the engine following the original O2 sensor cable:




2) Now get your welding wire, tape, and the new O2 sensor. Attach the welding wire to the new O2 sensor, and make sure it's tight.
In the front, this looks like this:





3) Now you put the lift up, and walk under the car, and search for the welding wire, and pull it slightly and softly, if you have any obstacles, put the lift down, and make sure you push as from the engine to the exhaust. Lift the car in the air again and pull again, now it will work fine, and comes right down
(I already undid the tape and then took this photo):



4) Put the new one in place with wrench size 22: Very easily accessible. and bring the vehicle to the ground afterwards.



5) It's the first green connector on your passenger side, at the bulkhead, TOP LEFT in this photo below:
