If the air pump is working then it's going to be the one way check valve at the manifold. It's common for the check valves to go bad before the air pump, check the pipe from the pipe to the manifold too.
Before you get that far i believe there was a TSB and the warranty is 5 years to the emission system on vehicles. Looks like your close to the end of your 5 year so step on it to the dealer while you can still get a deal on this repair.
Good luck and hope this helps.

This is actually an easy swap out. Remove the electrical connection, remove the retaining bolt and pull out old one. I believe the sensor is located in the front passenger side of the engine on this particular model.

The code indicates an issue with the Throttle Actuator control. This is a little motor on the throttle body that opens the throttle plates at idle. That control motor may be bad and thus, causing a low idle.
I hope this helps.
