99 S70 Check Engine Light

The temp has been all over the scale here in the last couple of weeks so I turned the AC off one morning. On the way to work the "Check Engine" light came on. I was going to take it to the shop to find out wha the problem was and the light went out later that day. I ran the AC for a couple of days and then turned it off one night, the light came back on! If I leave the AC on, no light.

What could be causing the light that is associated with the AC? Will a code be trapped even though the light is off?

Thanks,
Vern

Never heard of it- I think it's just coincidence.
