O2 Bank 1 Sensor 1 and Bank 2 Sensor 1 issue
Hello everyone,
I have a CEL and I checked the codes. I had 6 codes but after erasing them to see if they would return, I got back only P0030 and P0050. 02 Heater sensor circuit Bank 1 sensor 1 and bank 2 sensor 1.
What are the chances of 2 sensors going bad? How could I test them? The community seems very limited in information for these cars unfortunately.
Thanks in advance

Out Of Control!!
You don't bench test 02 sensors you test them on the car and the heated ones,before the cats you test at idle--normal range for your engine is -200 to +1000 mV and if after 2 minutes at idle the value differs by 300 mV it's bad!!
FYI those OBD codes are not in the DAS fault library for your car--who's scanner are you using??
