Today driving into work (in the rain) my 2002's CEL came on. The vehicle still seemed to be running fine. A few hours after I got to work I came out and checked it again, the light was still present. I checked the gas cap and have been looking through the manual when I can.
I'm wondering if this is somehow connected to the rain? How do I go about getting the CEL code checked to find out what the issue is? (preferably a non dealership solution)
Thanks in advance for any advice/ideas.
