The evaporative emission system is designed to prevent fuel vapors from being released into the atmosphere. The vapors are absorbed and stored by a fuel vapor (evap) charcoal cannister until certain engine conditions are met, then the vapors are purged and burned in the combustion process. I would lean toward a faulty purge solenoid based on the condition that you describe. I would also look at a faulty gas cap. The gas cap is an integral part of the evap system and will cause these kind of problems if faulty and not venting properly. Hope this helps and that you find a resolution to your problem.

Sensor 2(s) are those aft of the catalytic converter(s).
The pre-cat sensors typically fail more frequently than those post-cat.
The codes you cite are related to all sensors.
It is worth running a test of the sensors. Most garages can do the tests without any disassembly and for less than the cost of replacing any one of the four. Then you can replace the faulty unit with confidence.
