EGR does not reset.

What is your question?

I have a 2004 Mitsubishi Outlander 2.4 and it doesn't pass the smog check because the EGR is not ready but everything else does pass. My engine light is not turned on either. The mechanic replaced the egr, cleaned up the area and told me to drive it. I've been trying to reset it for over a month with no luck and is extremely frustrating. What can I do??? My car runs perfectly fine.

How long has your 2004 Mitsubishi Outlander had this problem?

2 months
