2003 f250 O2 sensor fuse

The check engine light is on still after I replaced both bank 1 & 2 O2 sensors. Is there a bad fuse that is keeping the engine light on?

  1. What are the check engine light codes? Why did you choose to replace the O2 Sensors? was there an O2sensor code?

    The check engine light can come on for hundreds of different codes. CODE LIST HERE

    Once you determine the code, post back and we can work further on the how to correct it.
