Default Evaporative System Monitoring Status

what happens if you have an AutoTap and for a month now, whenever you scan your car, it says the Evaporative System Monitoring Status is incomplete??

That means that the evap status is incomplete.

How many miles/run time have you put on the car since resetting the code and fixing the problem. This can mean there is still an issue with the system.

I'm not sure if I even fixed anything.

I probably have pulled the battery twice, hoping it would relearn the fuel trim.

But I've easily but 400+ miles in between...

Daron, didn't you say that your FPR had issues in another thread? If so, I believe you need to resolve that before you'll get rid of this.
