Hi helpfixit,

Thank you for the donation.

The generic code of P0400 means a EGR system malfunction whereas P1522 is not listed by Mazda under their error codes.

There is a possibility not any items are faulty, just might be some cleaning needed.

I would suggest checking/cleaning the EGR valves and passages first.

Hi helpfixit,

You need to remove the EGR valve and clean it by clearing the carbons that has accumulated in the valve passage. The passage in the manifold on which the EGR seats alsp needs to be cleared of carbon deposits. Some carb cleaner and a piece of flexible wire would do the job.
