P2430 and P2432 Increased emissions

I will like to ask for your help.
I have check engine light with the following codes:
p2430:Sec Air Injection System Airflow/Press Sensor Circuit Bank 1
p2432:Secondary Air Injection System Air Flow/Pressure Circuit Low Bank 1
Increased emissions

I've done my research and it appears that I might have a crack on the suction hose(11727838504) or bad sensor. I stopped at a dealer and was quoted $200 for the part.
Is there anything else I should look for before purchasing the part?
The car drives fine but I don't know if it's safe to drive the car with the check engine light on.

Any help will be appreciated.

I had this part fail on my car twice, first time it was replaced by dealer under warranty, second time I did it myself. There is no risk in driving whatever, the part is only active in the first 30 seconds or so of the cold start cycle. It blows extra air into the exhaust to heat up the cat as quickly as possible.

If you do the work yourself I recommend buying the part from fcpeuro, who give a lifetime warranty so if it fails again they will give you a new one free of charge

That's good to hear because I daily drive this car. I purchase the part off eBay for $55 shipped.
