P2404; P2402 CEL Codes
 

Hey all,

I have a 2007 CX-7. Recently the CEL came on, and I checked the codes and came back with 2402 & 2404. I took it to a Mazda dealership to confirm and they told my wife that the leak detection pump needs replaced. Being a more of a DIYer, I was wondering if this is in fact a DIY job, or if I should bring it somewhere? Is it easily accessible? Anything I need to know specifically if I DIY?

Thanks in advance!
