hi ...

I have a mazda 3 2005 hatchback, european spec.
I bought the car used, and the previous owner told me that the amb stopped working during snow last year. now it reads much higher than the real temp outside. for example it can be outside 32 C
and it reads it as 66 .

what could be the problem ?? should i replace the AMB sensor ?? if yes where can i buy it online ..and if anyone knows where it is located and how to replace it would be very helpful

thanks
