For the air we breathe it is important to get this fixed but as far as
car function the only difference you should notice is the red light
glowing at you. Were it mine I wouldn't worry about it until I was
back on my feet again or until I was coming up on an emissions
inspection.

OK thanks

careful on the mazda
if it is a cat efficiency error it could be a lower then spec cold start
idle or a 02 sensor out of range and of course

What does that mean exactly?

it means the the computer ramps up idle in cold start when the ambiant temp
is at the predetermined value and does so that the cat, gets warmed up faster

reducing emissions output
