Help help help!!!!

My car had a flat tire, I jacked it up to replaced with the spare tire. After that I replaced the air filters. The next day CEL came on. Without doing anything I drove for 2 days and it was gone. A day later it came on again and has stayed on. The car is driving normal, it doesn't feel like it's losing any power, idle is great (500 in Drive, 800 in Park). It's still on the spare tire. I've read and taken it to Autozone for to check, the results are

P0150 O2 sensor circuit malfunction Bank 2 Sensor 1
P0155 O2 sensor Heater Circuit malfunction Bank 2 Sensor 1

Can the car be perfectly fine (steady idle, no performance loss, etc.) is O2 sensor is bad? Could replacing Air filter cause this?

Does anyone have any suggestion fixing this?

Thanks
