Jeep Liberty Sport check engine light.

I have a 2002 jeep liberty sport 3.7lts 6cyl, the check engine light had came on, I took the jeep to pep boys so they can put it on the scanner, what showed was the oxygen sensors, I changed all 4 oxygen sensor and the check engine is still lit, so I took it back to pep boys and again the jeep was scanned and still what reads is oxygen sensors, I took it to auto zone so they can scan it as well and same thing oxygen sensors, once I told them that they where replaced, I was told that it could be a fuse or the relay, I don't know what fuse and where is the relay I was told to look under ignition (is this right) I check the manual and the only thing I find is fuse number 36 ignition run/start-orc/left and right siacm or fuse number 37 ignition run only-orc and as far as relay don't even have a clue... has anyone out there gone through this problem??? I need your help.... thank you...

Did I miss the part where codes were cleared after sensor replacement?
