- 1997 Explorer XLT
The check engine light recently came on in my 1997 Explorer. I took it to an auto parts store and had the codes read. There was only one code. It said "O2 sensor circuit slow response (bank 2 sensor1)." The motor is 4.0 SOHC. My understanding is that there are 4 O2 sensors (2 up and 2 down). When it says bank 2- sensor 1..which one is it?
