Help! Codes P2227 and P1487!

Hey everyone! I need help diagnosing the P2227 and P1487 codes that have been plaguing my '04 3.0 Mazda 6.

Here is the information that I found elsewhere and believe to be accurate about the codes:

P1487 - EGR boost sensor Solenoid valve circuit malfunction ON 2 CCM

P2227 - EGR boost sensor circuit performance problem ON 2 CCM

This seems to indicate a bad boost sensor? Well I recently replaced the boost sensor and I've still been battling the codes for about 250 miles. The car is running fine and my mileage has not changed noticeably.

What do I do next? The nearest Mazda dealership is an hour away and I would like to be able to sort this out on my own. However, I need to pass emissions by the end of the month.
