Bank 1 O2 sensor
Is there a DIY for replacing the bank one O2 sensor? I started getting codes again after replacing the cat converter last year? The O2 sensor was replaced before but I'm not sure which one. How many O2 are there on there?

Four. 2 on each bank I just replace Bank 2 Sensor 1 yesterday.
