Sorry, your question is not very clear; not sure what you need?
The Maintenance Required Light is not the same as the Check Engine Light. The Maintenance Required Light is telling you that there is scheduled maintenance that needs to be performed. It may mean it needs an oil/filter change. To find out what needs to be done look at the maintenance schedule in your owner's manual.
A 1992 Caravan is fuel injected. No carb.
I changed the battery and voila' - no more light.
The maintenance light,You will need to take it to a Dodge dealer to reset it. Or get a DBR-2 code scanner.BIG $$$
It is a reminder to do preventative maintenance. It comes on after a required number of mules. Does not mean that there is a problem wirh the vehicle. You can use a key to push in the slots to reset to green.
The maintenance required light requires a scan tool to be reset.
