This light may come on for various reasons. It could be one or more things at once. Usually only one.

The best solution would be to take it to an auto parts dealer and have them run a diagnostics test. This is usually free and takes 5-10 minutes to perform. They will do it right in thier parking lot. It's a small hand held device. You will need to start the van, leave it running and they will plug the device in and punch in some buttons.

After about 2 minutes they will read you a list of codes and tell you what each one indicates (i.e. parts or components that are or may be faulty and need replaced).

Please let me know if you need any further assistance with this matter.
