I took my 2000 Ford Mustang 3.7L in to read codes, then cleared (bad EGR) Then I went to have my Car smogged and they told me it passed, but that it had been to soon since clearing the codes (Smog test computer came back with "[b:5eb1d734db]System's Not Ready[/b:5eb1d734db]" and told me I have to bring it back within a month (basically saying they won't let me pass until the "System's not ready' code clears -[b:5eb1d734db] How long does that take, or how can I expedite this?[/b:5eb1d734db]

Thanks for any help I can get.

Yep this is because the monitor do not set unless you drive the car about 40 miles shutting it off and letting it cool down at least twice. This will reset the monitors and give you a passing smog.

Suggested Repair

Drive about 40 miles, shutting the car off and letting it cool down at least twice so the emissions monitors reset before the smog test.

Conversation Summary

The owner cleared codes on a 2000 Ford Mustang and the smog test reported System Not Ready. The expert said the monitors need about 40 miles of driving with at least two cool-down cycles before they set and the car can pass smog.
