Do you hear the air pump run when you start the car? No? Check the A.I.R. pump fuse in the under hood fusebox. if it is blown then you probably need a new air pump motor. If the fuse is not blown then the relay could be the culprit. if you can hear the pump running when you start it the engine then you probably just have some wiring issues from the relay to the ecm it can still work ok but fail the resistance test that the computer runs randomly. Give some more info and I'll help you through this.
Please rate this response , and let me know if ya need more help!

most ecu controlled vehicles have a 'limp home'mode if 2 or more fault codes are stored,it is designed to get your attention before damage is caused and to get you to the nearest w.shop to fix,i would have codes cleared and retest vehicle,it is the cheapest and 1st option for any shop,some late models even have excessive mileage past service interval in the 'limp' program

This is a pump that sits underneath your front bumper on the passenger
side. It is about the size of a baseball and has two hoses going into
it. I would suggest you replace it yourself as it would cost you about
$360.00 if you were to go through the dealer.
Water intrusion is what will typically kill these electric pumps. There is a Technical service bulletin (#04-06-04-015) Regarding this problem, according to the tsb, you will need a new pump and there is a hose assy. #12590627) that has you reroute the pump from future water intrusion or it is guaranteed to fail again.
Although I have had water in the pump I did not see any indication of the inlet hose as the cause. It was suggested that the one way metal check valves ($15.00) that mount to the rt & lt exhaust manifold are worn and allow water from the exhaust to get sucked back into the pump. I first replaced the pump and within a week of dry weather driving the light came back on. I checked the pump and it was again full of water. I just replaced the valves which had deteriorated on the inside. So hopefully this will eliminate the problem. Note - The valves are impossible to remove without removing the 1/2 tubes (held on with 2 nuts) they are attached to the manifold with. The valve threads seize to the tube thread and had to be clamped in a vise to remove - I actually had to hacksaw the valve section to get it off the pipe. Careful as not to damage the threads.
Good luck and try autopartsdirect2you for a new pump and it has life time warranty.

Some owners may comment on the check engine light being illuminated. Upon investigation, the technician may find a DTC P0410 indicating that there is a concern in the secondary air injection system.
Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump.
Replace the AIR pump and install a new inlet hose and solenoid tube assembly using the following procedure:
Raise vehicle on hoist.
Remove shield covering AIR pump.
Remove hose and vacuum lines from pump and solenoid.
Remove AIR pump inlet hose. Do not re-use.
Disconnect electrical connectors from pump and solenoid.
Remove pump mounting bolts and pump.
Transfer isolators from the old pump to the new pump.
Install new AIR pump and bolts to vehicle.
Tighten the bolts to 17N·m (12.5 lb ft)
Route new hose assembly up between engine and fender. It should come up near the area between the battery and the coolant bottle.
Connect new inlet hose to pump inlet.
Connect old outlet hose to pump outlet.
Connect electrical connector to pump.
Connect electrical connector for solenoid to connector on the new hose assembly.
Connect the hose with the white nipple to the vacuum source hose.
Connect the remaining hose to the shut off valve.
Install shield covering AIR pump.
Remove coolant reservoir nut nearest the battery.
Route new hose assembly between the battery and the coolant reservoir with the solenoid on top.
Install the solenoid bracket onto the coolant reservoir stud and reinstall the nut back into the vehicle.
Use a wire tie to keep the new hose assembly away from the engine. On four cylinder engines, tie to the AIR outlet hose. On six cylinder engines, tie to an available hole in the radiator fan shroud.
