My check engine light came on and i got it checked out at AutoZone and they told me that my secondary injection system had an incorrect flow. i was then told that the probable cause could be a leak in the valve, Faulty air combination valve, faulty air solenoid calve or faulty air pump motor. i have no knowledge of cars and i would like to know how much i am looking to pay if i need to get any of these fixed any help?
Who told you these things? Autozone? Those guys don't know their kester from a hold in the ground about electronic engine control systems.. This is a very expensive part, have a qualified technician diagnose the problem and replace the correct part or make the right repair.

the air pump should start when car is cold, if you do not hear a small airplane under your hood, than it is not functioning, if you do, you'll need to do other diagnosis (checking vaccum lines most likely), but being such a new car, a dealer would probably be under warranty.

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.

Condition
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.
Cause
Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump.
Correction
Replace the AIR pump and install a new inlet hose and solenoid tube assembly using the following procedure:
Prep vehicle.
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
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.
Lower vehicle.
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.

Hope that helps

More than likely the secondary air injection motor has failed, this is the case most of the time, check all the hoses and verify the connection's and if u find nothing openly wrong replace the secondary air injection pump assembly.

the air pump is located on the engine towards the front of the vehicle and has apx. 3/4 diameter pipes running to and from it. it is apx. 2 fists in size and it is black plastic. one of the lines on top of the air pump runs to the other side of the engine towards the firewall. at the other end of that pipe is the valve. disconnect that pipe while the vehicle is running. no air out of the pipe means bad pump. air coming out of the pipe means bad valve
