Do not change random parts. That is by far the most expensive and least effective way to diagnose a problem. It will cost you less to take the car to a mechanic. Also, no two sensors are ever exactly alike. The Engine Computer learns the characteristics of each one when certain conditions are met. Each time you put in a new part, that changes something the computer hasn't learned yet so you'll be inserting a whole new bunch of variables. If you DO resort to tossing parts at it, when it doesn't help, put the old part back in before continuing on.
You can get codes yourself. Chrysler made that real easy for you. Cycle the ignition switch three times within five seconds from "off" to "run", leave it in the "run" position, then watch the numbers show up in the odometer display. Be aware those codes will never say to replace parts. They only indicate the circuit or system that needs further diagnosis.
