Check engine light

[bebo3]

Hi recently i changed my 4 oxygen sensors on my explorer 02 and the egr valve too, because that was the message the computer was acknowledging as the failure, and after 10 to 15 minutes the light came on again, havent put the diagnostics computer again..but i was wondering if you know what would be the problem now? or if it just to reset the computer again?..i would gladly thank any help given

What were the origional codes? Did you clear the codes after replacing the parts? Anyones guess right now is just that - a guess. Codes are great to have when trying to diagnosis a CEL
