SOURCE: 05 saturn ion with codes of p010
p0106: manifold absolute pressure/barometric pressure curcuit range/performance problem
p0496: EVAP during a non-purge condition.
Its best to google these codes to find a solution and probably why there on and how can you get rid of them.

This sounds correct. Replace the O2 sensor and clear that from the equation. If you have a faulty check valve on the gas pump it is allowing fuel to come back down the fuel line and what happens is the pump has to work a few seconds to fill the line back up and clear the air bubble. Other than a nuisance this should not hinder operation of the vehicle once it is running.

Code 496 is not about the gas cap.
The code means the computer has detected pressure in the EVAP system when it should not be there.
The EVAP system consists of lines and valves that vent the gas tank to the vapor canister and the engine.
The problem could be one of the valves or the pressure sensor. You may need a shop manual to get the diagnostic steps to test the system.
