Just wondering if these are even worth tracking down.

Got
P0453 Evaporative Emission Control System Pressure Sensor High Input
idling at Starbucks today.

Any ideas?

I looked around and it's just an emissions code.
Should I just ignore it and disable emissions error checking in the MISC ECU options?
(rather fix it than just sweep under the rug)
Maybe it's running extra rich at idle?

Does anyone else get this code thrown?

I really don't want to dive into the fuel pump but maybe the filter is dirty or something.
