02 Sensor short
So my bike (2012 SG) hasn't been running correctly for the past two days. It had significantly less power and exhaust note sounded conciderably different. I pulled the codes and got the following.
ECM: P0151
Rear 02 Sensor Lean
ECM:P1356
Rear Cylinder No Combustion EFI
I inspected the O2 sensor and realized that the wire had been rubbing against the metal pipe and rubbed/burned off the plastic shield and was shorting against the exhaust. I taped it all back up and reset the codes. The bike still isn't running correctly. I am assuming I need to replace the 02 sensor but wanted peoples opinions before I spend $100 on a new one. Would a short permanently ruin the O2 sensor? I have the Power Vision from Fuel Moto installed.

Okay, so I replaced the O2 sensor. The bike isn't throwing anymore codes. However, it still doesn't seem to be running correctly. Before I caught the short, I had a loud metallic sounding backfire. I have replaced the O2 sensor and the spark plugs. Any thoughts? Could the short have damaged something else on the bike?
Thanks

I tried that. The backfiring has gone but the bike still isn't running 100%
