Hi, this is just a reset issue. sometimes the CPU can become confused. the original warning that informed you about your gas cap is still in the cpu's memory. you will have to reset the cpu and, this will clear the warning. After the reset, it will stay off. chevy cpu's tend to do this from time to time.
Another thing that will trigger the "Service engine soon" light is starting the vehicle and putting it into gear before all the test lights on the dash have gone out. They are testing for certain parameters and when you put it into gear early, those parameters are not reached. The computer sees it as a fault. Normally, it 5 - 6 restarts to reset this. The key must be removed between each start.

Hi Gene:
I'd suggest trying to start from the beginning with this.
Try disconnectinf the battery and charging it fully.
When you re-connect it, the "service engine light" may not be on . that would be nice. If there is a problem the light will come back on. Make sure the gas cap is screwed on tight.
The battery not holding a charge is ypically a separate problem from the service engine light.
99% of the time, the gas cap wasn't tightened properly, or is leaking. Make sure you twist it tight and it clicks a few times. If the "Check Engine" light stays on after a few days, buy a new gas cap. Again it may take a few days to clear.
Get gas cap from dealer as some vehicles are having issues with the after market caps. What is the actual code and what's the vehicle year, make and model?
Hi George: If the "Check Engine" light came on soon after a fill-up at a gas
station, check if your gas cap is closed properly. If the gas cap wasn't
on tight, this could be the problem. Secure the gas cap properly and if
there is no other problems, the "Check Engine" light should clear
itself out in a few days of driving. If the gas cap was tight, there is
some other problem. Have your car computer scanned to see what is wrong.
It could be some minor problem, but it also could be something more
serious that can cause more damage to your vehicle if not repaired in
time. Some garages or parts stores often offer to scan your computer
for free. Others will charge you a diagnostic fee. If your car is fairly
new, I'd advise to visit your dealer for this, because it's possible
that the problem is still covered by the original warranty and can be
repaired for free or a minimum charge. Check your owner's manual for
more details.
Hope this helps; also keep in mind that your feedback is important and
I`ll appreciate your time and consideration if you leave some
testimonial comment about this answer.

Have you checked the gas cap to see if it is on tight? If you purchased gas in the last couple days it might be the solution. Tighten the cap and drive a couple days to see if the light goes off. If the cap is loose, you might need a new cap.
I would take the Odyssey to Autozone (or some other of the same sort) and have them hook their reader up to you OBD-II port and get the exact codes that your malfunction light is indicating. They don't charge for that, and it will help you know exactly what the problem is.
Hope this helps you.
Thank you! I thought I was going to have to go to the dealership!
That makes sense. I did put the car in gear right away! Very Helpful, thanks so much!
