The service engine light is on because the computer has seen a problem with the operation of the engine systems, what happens is the computer is always monitoring all systems and when theres a problem the computer stores a code explaining what system has failed, for example only there may be a code po302 cylinder 2 misfiring. this would tell you that the number 2 cylinder is misfiring, with a little testing you would then check it out to see why this is happening.the first thing you need to do is have the codes read, there are many auto part stores that will scan the computer and give you a print out of the codes, if you write back and list the codes i would be able to help you further, good day.

Service engine light stays on. changed oil last week.


The service engine light does not refer to oil changes, it is used to check for engine fucntion and emmision control sensors. Most likely you have a fault in one of the emmission control sensors.

"Service" light just started coming on over the weekend. It comes on, stays on for about 5-10 minutes, then goes off. The other lights - check engine (I think), oil, etc. - come on when I turn on the car...


The light is set to light by milage and it is to let you know that the next service is due. This is reset by removing the rubber grommet that is to the left lower corner of the speedometer and depress the reset button.

Check engine light stays on


It means that your car is due for a service. Ignore it at your peril!

Any well-equipped garage can do the servicing and then reset the service interval counter so that the light goes out.

Engine service light stays on after servicing


I am going to assume that you do not mean the Check engine light that would trip DTC's.

To reset the service light turn the ignition to the on position (without starting the motor) and push the brake pedal three times within 5 seconds. Light should turn off. This is the procedure for 1999 Caravans and I suspect the 2000 is the same.

Coolant low light on and check service engine


If your coolant low light is on it usually means you need to add coolant to the plastic reservoir, but if the coolant level is ok in the reservoir but the light still stays on then the coolant level sensor in the reservoir is not functioning properly. The check service engine light can mean anything from serious engine problems to a simple oxygen sensor reading that the computer didn't like. You can stop by your local auto parts store and they will read the codes and tell you exactly why it is on and what the computer has detected.

Service engine light stays on


the check engine ligth just means you are not passing emissions right now. Coud be due to loose fill cap at some time, or filling the tank with the key on.
Try disconnecting the battery ground cable for an hour. Then reconnect and drive for 10 miles until computer relearns engine changes. It may run rough for 10 miles.

If still on, go to Autozone and ask them to perform a free computer scan & get the fault code. It will tell you which sysem to check.
