Erase the code and see if it returns. If it does, replace the valve. What engine do you have? If it is a 3.4 it should be right on top. One plug and two bolts.

you can easily replace it yourself for 50. it just unbolts and you bolt the new one on. You might have to remove a couple of things but nothing too hard,

Its right in front of the engine as soon as u open the hood On the left side. It has one electric cable connected on top and a pipe with the diameter of a dime at the lower side running to a lower section of the engine.
