O2 Sensor

[mpab]

Hi my check engine light came on my 2003 YXL Denali so I stopped by Advance Auto to have them check for the code. He told me it was a P0135 O2 sensor heater circuit malfunction bank 1 sensor 1. He also told me I should check the the fuse first.

Could you Please tell me where the fuse is at. I looked inside the fuse box under the hood but I'm not sure if I'm looking in the right place. Your help would be greatly appreciated.

My answer was in my own question. The fuse is in the fuse box under the hood and the fuse is marked "O2-A" and "O2-B".

Thanks for the all the viewers.
