Sure, here is the sensor location so you can change it out.

The P0135 code indicates a malfunction in the oxygen sensor circuit for bank 1 sensor

Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.

I just replaced that sensor; I replaced it when I installed my new downpipe and cat back. Previous owner had installed a bad after market down pipe and cat back. I used a Bosch 17319 for that sensor and the code on my reader said that the O2 heater circuit was not working. I am able to clear the code and I cleared it last night. It popped back up this morning when I was leaving for work and I was able to clear it again.

Okay, please check the fuse #8 20 amp in the fuse panel under the hood. Here is a guide to help to check the fuse for power with the key on:
