Sensor error message despite replacing
Despite replacing the bank 1 sensor 1 up-flow oxygen sensor in a 1997 Lexus ES300 with a single piece sensor and harness, my check engine light still keeps coming on after multiple resets. The computer did properly recognize when I replaced the knock sensor. Any suggestions as to why I'm still getting the same reading after replacing the proper sensor? I also tried two (2) OEM versions, which didn't work. That's why I purchased the more expensive original equipment version. Other restorations coming along quite well
