'Check engine' light. Very cold here this morning. Could frost distort a sensor reading and light the warning lamp? 200 1990

Hi.

And could someone please post the reasons why this warning comes on and in order of importance...

-I know of the o2 sensor but it was replaced last summer. Could something as simple as a week battery cause this?

-Is it in any way related to the electrical system?

Thanks to all, this is a great site.
