P0410 = Secondary Air System Malfunction
Not sure if you were looking for more info than just that, but, here goes.
This pump' primary responsibility is to improve start-up exhaust emissions (if you're having issues, it may be covered under warranty).
If it's not covered under warranty I would first replace the relay.
Normally the relay goes bad, overheats and cooks the fan motor.
Hope this helps

The dealer near me charges $365 for a 4-cyl, $395 for a 6/8 cyl, or $425 for a 12-cyl. The only actual repair/maintenance you get for that price is an oil change (with Mobil1 and the MB filter, which are CRITICAL, ~$120 on its own) and tire rotation. This makes a lot of people think it's a scam, but really, it's a little steep, but definitely worth doing. The rest of the service consists of a massive inspection of your vehicle covering the following items.
-- Fluid levels
-- Tire tread/pressure/wheel condition
-- Air filter (inc. clean out housing)
-- Cabin air filter (inc. clean out housing)
-- Lubricate sunroof rails, locks, hinges, and seals on body.
-- Drive belt and tensioner
-- HVAC system operation
-- Instruments, cruise control
-- Wipers/washers/lights/horn
-- Windows/sunroof operation
-- Hoses
-- Transmission fluid
-- Brakes
-- Chassis/suspension
-- Driveshaft, inc. flex discs
-- Road test
-- Reset maintenance light
This is actually pretty essential to do, despite seeming like a lot of money for not much work. I have very rarely done one without catching a few things that the customer needs, and often it was a problem that would have gotten far worse had it been left to its own.

With the key in position 1, hit the odometer reset button on the left on the cluster 3 times in a row. The cluster should beep once. scroll through the multifunction display with the page buttons until the display shows the onboard voltage screen. It will say something like "UB: 12.2 V" scroll threw this menu with with the up/down until you reach the "service menu" page. scroll down to "confirmation" press +, confirm full service with +. Wait till it says service confirmed. cycle the key off and then back on to position 2. Scroll to the normal service menu where it normally says how many days or miles till next service. If the service was reset correctly, it will say "service display not possible" for a few minutes while it recalculates. You must cycle the key off and back on before it will back out of the onboard diagnostic mode. If you dont back out, the esp/abs/bas lights will illuminate when the car is started

I replaced the pump relay and so far it's doing good. Takes about 3 days for CEL to come on but cooling fan isn't having problems any more. Sometime it would come on when cold! So thank you very much for the relay suggestion !
