Replacing O2 sensors
Hello all,
Recently I have been having recurrent issues with p0135 code popping up. My OBDII scanner is signaling a faulty Bank 1 O2 sensor which I believe is on the left front sensor. I'm thinking about trying to tackle this one myself, but if it seems to difficult or laborious I may drop it off at the dealer for a warranty repair.
Anyone have any helpful diagrams or DIYs out there on sensor replacements? And yes I did search......
Thanks in advance
Courtney

It should say Sensor 1 or Sensor 2 as well and Bank 1 or Bank 2.
Sensor 1 is the one before the catalytic converter closer to the engine, and Sensor 2 is after the catalytic converter.
Bank 1 is the passenger* side. (Edited this to correct it)
They should all be pretty straight forward to replace but you're gonna need the car on jack stands or a lift.

I highly recommend you purchase the tool attachment to your ratchet which helps remove the sensor. Its cheap and it makes the job much easier.

Bank 1 is actually the passenger side. Just find out if it is the Sensor 1 (pre-cat) or Sensor 2 (post cat). Replacement is easy. Make sure you use some anti seize compound on the thread IF the new sensor does not already have it.
