Her trac-light was on because she hit the button on the side of the shifter and did'nt realize it. You have to get the car to a shop to have the computer scanned for the code of the service engine. Hers would go on and then go off the next day. Not so simple 1 would seem. When the temp guage read nothing and the service light was on we took it in and found a cracked intake manifold where the sensor screws in. The aluminum is so thin there. Then found injectors not properly sealing pulling air past them. Both were remedied. Now 3 weeks later the light is on again. It go's back to the shop tomorrow. Car runs perfect. I expect to find some sensor or another leaky injector.My mechanic is great and very patient with the problems.Also found that the wires that run the fuel pump at the tank--if you just nudged them you could turn off the pump. That was the stalling problem-the wires were checked and the pins at the plug in were cleaned and filled back up with electrical grease. Hope you have some better luck than I. I'll tell ya what the next code reading is tomorrow. I also own a 2000 Jeep Cherokee Sport--talk about needing a good mechanic!!!

a blinking light means its really important to get it serviced unlike a solid SES light
