I have had my Mazda for 3 months.
Aboutr 1 month ago the check engine
light came on. I checked the gas cap
and found it was loose. The light went
out. About 3 weeks ago the light came
back on. I took it to the mazda dealer
and they said they fixed it. I got the
car back and the light came on that
night. I took it back to the dealer.
They said it was a sensor and they had
to order it. It sould be in next week.
I hope this is the problem!
