Sad day, started car up last night and the 'Check VSC' & CEL came on. Ran diagnostics and got a P0031 & P0051.

P0031: HO2S Heater Control Circuit Low Bank 1 Sensor 1
P0051: HO2S Heater Control Circuit Low Bank 2 Sensor 1

I do have PPE headers installed along with the simulator. When the headers were installed I went ahead and installed new A/F sensors just in case the old ones stripped when removed. I've had them installed for 3 months without any issue. Any reason why both would go out at the same time?

I believe I just found the problem, looks like a blown fuse

Put in a new fuse and cleared the codes. Started several times with no problems. Codes just came back, looks like I might have a short somewhere? Dangit!

What spot in the fuse block was the blown fuse found?

Check for melted or pinched O2 or A/F sensor wires....

See pic for reference.
Did a little inspection tonight and from what it looks like the A/F sensor wires to the header on Bank 1 came off the clip and melted from the heat of the headers. Looks like I'll be doing some wiring tomorrow

use heat wrap after you fix the wires. same thing happened to me but mine was on bank 2 side. replaced wires, wrapped it in heat wrap and no more cel

After wrestling with the wires, I finally got to the problem. The cable came off a clip and burned itself to the headers. Respliced the cable and everything is working great.
