I just changed my exhaust today and I think I messed up the O2 sensors

The check engine light came on so I checked the codes this is what I got

2 code.

P0135 02
Sensor heater circuit ( Bank 1 Sensor 1)

P0134 02
Sensor Circuit No Activity Detected (Bank 1 Sensor 1

I think it might be there first o2 sensor before the cat any help would be grateful also where can I get aND aftermarket O2 sensor that is not a lotus brand that is overpriced

Both sensor are the same part
Switching them over will show if it a sensor fault as the fault code should follow the sensor. To bank 2
If it the fault code remains on the Precat side then it could be a wiring issue.
What exhaust did you install ?
