My check engine light on 2008 Suzuki Forenza

I took my car to autozone to get a read out of the problem and they gave me this error message: p2a01
The car only has 20,000 miles on it and this problem occured two weeks after purchase from dealership.

This problem should be covered under your factory warranty at no charge. We can diagnose the problem for you if they can't.
I think you didn't get the code number right, it should be a letter followed by 4 digits. Try again.
