Default Check Engine Light Came On

If it is

I only redo the gas cap if I get an of the following codes:

P0455 "Evaporative Emission Control System Leak Detected
(Gross Leak)"
P0456 "Evaporative Emission Control System Leak Detected
(Very Small Leak)"
P0457 "Evaporative Emission Control System Leak Detected
(Fuel Cap Loose/Off)"

The codes you list may are not standard and are not generic. Standard
codes only go to p0850 or so for ODB 2 systems.

Call your Mazda dealer and ask (they are in the phone book)
