It's not the oil, the coolant, or the transmission fluid. Does anyone know what else I should look for and how?

take it to the auto parts store. They have a OBD gauge they can check it with.
This should point you in the right direction.

Check engine light is a nuisance. I have (family and business combined) 9 vehicles on the road, and right now 6 of them have check engine light glowing away. It turns out that the most common defect signaled by that dang light is a defect in the check engine light circuit. I can turn it off in several of the GM vehicles by removing the negative battery cable, waiting two minutes and hooking the negative cable up again. Two snags. First is then I have to re-set the clock, the radio, the A/C and all. Second snag is, a week or two later dang light is back on. So what I do is keep an eye on the oil and coolant levels, watch the temperature and oil pressure, and ignore the light. Other things that can set that light off (depending on make and model of car) are oil change interval, oxygen sensor, mass airflow sensor, dirty or restricted air filter and things like that, but if your Venture is reasonably well maintained I'd still suspect the only problem is that double danged light. Among things it is NOT wired into are two very important ones. It is NOT rigged to warn of steering problems like low PS fluid level. It is NOT rigged to give any information about your braking system.

There are at least 1871 reasons why the light is on. The only way to know for sure is take it to someone that has a code reader and read the code. A lot of auto parts stores will perform this check free. That is the only way to tell for sure what is causing it. It may be something easy and cheap, and it may be hard and expensive, but the longer the light is on the worse it will get. You can waste a lot of time changing parts and checking , but there is no substitute for a good code reader.

The check engine light will come on to warn you when any of the sensors the computer monitors returns a value outside the range expected. If could be anything from a loose fuel cap to a bad injector. Take it to where they can put a scanner on it to read out the trouble codes, then you will have a better idea of what is wrong.
Some one is bound to suggest "take it to the auto parts store"
Don't. They sell parts, not diagnose codes.
Some one is bound to suggest disconnecting the battery.
Don't. All that will do is mess up your radio presets and perhaps your security system.

Start by closing the gas cap. You have to turn it so it clicks many times. So long as is sounds OK, just keep driving it.
If the light doesn't go off by the time you get down to 1/4 tank Fill it up again at a different gas station. If it does not go off after a 1/2 tank you may need to have it looked at.
I have a 99 venture and this happened to me not long after I bought it. It was a bad tank of gas in my case. The fill up cured it.

First disconnect the negative battery terminal, this will clear the codes and the light will go out, if the light comes back on their is a problem. Take your van to autozone and they will read your engine codes for you and tell you what the problem is. This will save you the 90 dollars that the dealer will charge you to read them. Once you know what the codes are you should be able to either fix the problem yourself or take it in to be serviced and not get ripped off.

Try replacing your gas cap. The vapor cap could be stuck and this would make your check engine light come on. Chevy's are bad about that happening.

Take your Chevy to a Chevy dealer. They have the correct diagnostic equipment to plug into your on board computer where it's memory will show a fault. They'll find the problem in minutes.

Is your mileage 90,000? Some vehicles have a switch to turn the light on at that amount of mileage. You just take it back to the dealer and he turns the light off and charges you a bunch of money.

90% - one of the O2 sensors, 10% - chevy. Have it scanned.
