HELP! Service Engine Soon Light!
 

After leaving the mall doing my xmas shopping Friday night .... My The Check Engine Light or Service Engine light( Icon that looks like a lil transmission thing) comes on. I am planning on doing a 12 Hour drive through the mountains from Vancouver to Edmonton on Saturday morning. Now what luck that this light comes on. I was trying to leave at 6am in the morning. Now my question is.. Is this pretty serious? Can I drive to Edmonton and then drive back and get it checked out? From reading the manual it seems to just be a emmision thing. I just don't wanna get stuck on the road or wreck my truck.

The drive is about 1200Ks. So about 2400k back and forth.

And advice would help!

Thanks

Apparently the most common cause of this is a loose gas cap. Did you refuel lately where you might not have closed the cap tightly? I had one come on once, after I had been fooling around with some fuses (while doing a mod), and the dealer checked it out, then simply reset the light.

Loose oil cap will cause the CES light as well. Did you top up/check your oil before the trip and not replace tightly? Or at all?
