I have 06 Ford F-250 I replaced the ekg and the check engine light is still on

What is your question?

I replaced the ekg and the check engine light is still on is there anything else that can make the check engine light to come on and say it's the ekg after you put a new one in so if the ekg is new can it be something else in the ekg system

What makes this problem better or worse?

No
