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?

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!

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

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.
