Check Engine light reset, how long till it's ready?

[SuperToph]

So I had some work done to fix an exhaust problem (darn catalytic converter)... The service center reset my Check Engine light, but told me I couldn't just get it inspected right away...I had to drive a bit.

I guess there are ODB II values that get triggered as ready once I have gone long and far enough.

My question is, how long, far and fast do I have to go before it's all good. Waiting in line for the inspection to be told it's not ready yet would be a PAIN.

Thanks!

What kind of inspection are you waiting for ? Was/is the MIL lamp on due to O2 sensor codes ?

It usually sets to "ready" within 40-50 miles.
Vary your speed but try to do at least 15 miles at 55-70 MPH.
Just do a "normal" drive cycle with varying speeds

It is an emissions inspection for Virginia... It was a bad cat that was causing the Check Engine light to come on...no bad sensors thankfully.
