P0141-o2 sensor
P1406-some other sensor

So what do you guys think I should start with, my check engine light has been on for awhile but I never did anything. Do you think all of the sensors just happened to go bad or do you think it could be some other problem? This post caught my eye since it involves some of the sensors so I checked the fuses but they're fine but im not sure which wires to check. So what do you guys think?

Might check in the under hood fuse box I think it's engine cont 1 & 2, location 25-26 or something like that. If you have a Powertuner, you can check your MAF frequency, O2's etc to make sure they look like they're operating like they should. If something doesn't look right, you can start looking there.
