Hi all, my check engine light is on and the code P0141 came up. Just want know where Bank 1 Sensor 2 is located? Is it the one furthest away from the engine directly behind the cat about halfway down the car? Thanks for your help.

its right after bank 1 sensor 1 and just before bank 1 sensor 3.

Yes it should be the one past the cat. Although, keep in mind, a code on your post cat 02 could also indicate cat failure. Do you have a hfc or tp?

It's the rear O2 after the cat.

stackhouse is correct, dont change pinpoint to the sensor, it might be the cat.

P0141 is a Heated O2 Sensor Heater Circuit fault code...this does not point to a bad cat converter...most likely cause is a bad (rear) HO2 Sensor or wire damage...i would bet on a bad sensor

My car threw that code along with some other cat-related code a couple times. Cleared it, but it would pop up after I did some hard pulls randomly every couple months. Dealership replaced my cat because it was done.

It always did smell weird too..light hint of a weird burning smell. After they changed it no smell. But again after a few really hard runs on the highway, hint of that smell comes back. My Evo eats cats!

I used to get P0141 intermittently, so I thought it was not enough anti-foul extenders (running catless), or maybe a tune issue. Eventually I replaced that rear O2, and no issues since. So yeah, +1 for the sensor.
