Question about 2004 Chrysler PT Cruiser
Nothing wrong with the car why is it on/
Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you need to diagnosed and repaired it. The list of possible codes number in the hundreds. The code itself doesn't tell exactly what component is defective - it only indicates where to look, or what engine parameter is out of normal range. You or a technician will have to perform further testing to pinpoint cause and the proper repair. Even if you reset the light, if the underlying problem is not addressed it will come back on.

This light tells you that the engine or transmission needs attention. It's not going to blow up if you keep driving it for a little while, if it's still running (red lights, like oil pressure, mean to stop RIGHT NOW).
Just changing the oil is probably not going to make the light go out. The light was turned on by the engine's computer, and indicates that the computer got a bad reading from one (or more) sensors located throughout the engine and transmission. Most auto parts stores can hook up a code reader to your car and read the trouble code stored by your computer. The trouble code indicates what system is not working properly and that may tell you what to replace to fix it. Or it may require more in-depth testing to determine the exact problem.
