Fuse box. Just look at the fuse box under O2 Sensor ( or 02 SNRS ). I think it's number 19 or 18 on the fuse box. Engine compartment fuse box.

Where do I find the fuse and/or sensor on my 2006 Avalanche? How easy is this to repair? Can I still drive my truck while I am waiting to get it fixed?
Thanks!

Yes you can still drive it. Only problem is that you may experience some changes on gas mileage and it will fail the smog test. What engine is your Avalanche? More than likely you have to replace the sensor and not the fuse to fix the problem.
-
Just replaced my engine on my 2007 yukon. Everything new. This code came up. What do we need to look for since everything is brand new?
-
The code is for the Front Heated Oxygen Sensor (H2OS) Bank 2, you could start by checking the sensor connection and the sensor it self. If the engine was replaced, more than like that sensor was removed as well. During the installation the it's possible that the sensor got damage or was not properly installed.
