Having problems with your 1999 Dodge Caravan ?
What does service engine soon light mean? - 1999 Dodge Caravan
Your car has sensor's installed on several parts of engine, transmission and exhaust system, any time any of those sensors stop working due to a problem on that particular part, the service engine light comes on. How you know where the problem lays?, there are tools called On Board Diagnostic (OBD) tools and they are sold and also if you take your car to a Auto Zone or other similar auto parts store they'll read the code of the "problem" and tell you which part of the car has problem.\012Hope it helps and please don't forget to rate the answer it helps me, thanks!\012P.S. comment if you need more clarification.
It means one or more diagnostic codes have been stored in your computer, telling you something is wrong and needs yours or a mechanics attention. If you stop at one of the big autoparts sellers, they will usually scan it free of charge and tell you what codes are coming up, and possibly what needs to be done to fix it. If in doubt, write down the code(s) and get back to us with those, and we will be glad to further assist you. Don't let it go too long, even though you may not detect any problems with the way the vehicle is running or driving, prolonging diagnosis, could cost more money later.
