We have a 2002 Chrysler Town and Country EL , 92,000 miles , V6 engine. We are getting a malfunctioning indicator light (OBD) that comes on. it is not flashing, only coming on. In the book it says if it flashes you need to shut off engine. Please help us understand what is wrong and how to fix it? Please reply in laymans terms , as we are not mechanics and know little about repairs ? Thank You Soo Much for ANY HELP WE RECEIVE.
