The Check Engine light means the Engine Computer has detected a problem and stored a diagnostic fault code in memory. Have your mechanic read the code(s). That will indicate the circuit or system with the problem, not necessarily the defective part.
If you want to try to read the codes yourself, it is by far the easiest to do on Chrysler products. All that's required is to cycle the ignition switch between "off" and "run" three times in five seconds, then leave it in "run" without ever cranking the engine. Then you count the flashes of the Check Engine light. It will flash two-digit codes as a series of flashes with a short pause between the first and second digit, and a longer pause between each code. If you can get those codes, post them in your reply.
