EVAP I/M Readiness Test

I just purchased a used 2008 Cobalt with <7k miles. The battery had been replaced, wiping any codes as well as requiring the I/M Readiness test to be performed.

The EVAP test shows as incomplete. It had been driven 250 miles since the codes were cleared, and I've driven it more since then. I tried idling the car at cold start, but I still don't get the "OK" for the EVAP test.

No codes have been recorded, only the incomplete EVAP test.

Any ideas as to how much driving should get this test completed?

Re: EVAP I/M Readiness Test

It looks like the test was finally performed after the vehicle was refueled. It came with a tank that was 3/4 full, and we ran through that without the test showing complete. However, after the first refuel I checked it with my scan tool, and all tests showed complete.
