There are too many reasons to list here. The "Check Engine" light will come on any time there's a fault detected by an engine sensor. Sensors measure everything from the amount of air flowing into your engine to the quality of air flowing out. There are knock sensors and coolant sensors. More sensors keep track of throttle opening, oil temperature and even the condition of fuel injectors. If your light is on you can visit your Toyota dealer for an analysis of the problem or, stop by any auto supply store that will loan an OBDII code reader. Plug the reader in under your dash (just to the right of the steering column) and follow the instructions. Depending on the quality of the tester you'll be shown a number matching a fault or text detailing the problem. Once the detected problem is repaired you can use the code reader to 'reset' (erase) the trouble code and the light will be turned off. BTW in the future it would be helpful if anyone asking questions on this or other automotive forums would mention the year/model of their car. Sometimes 4 cylinder vehicles of the same model require different answers than 6 cylinder. Solara's come in generation 1, 2 and 2.5 models sometimes requiring different answers for different generations.
