98 explorer 6 cyl. 4L Oxygen Sensors

I have a 98 explorer sport and the check engine light came on. I have an OBD II code reader and it showed I had a problem with an oxygen sensor. The code reads a problem with bank 2 sensor 1. I don't know which one that is. Does anyone know what each one of the sensors is called?


Thanks

Bank 2 sensor 1 is the drivers side sensor in front of the converter. What was the DTC number you read? If you don't mind me asking.

Thanks for the info. The DTC was 153 - O2 sensor circuit slow response bank 2 sensor 1

I have a 97 with a code 153. Did replacing the oxygen sensor fix your problem?
