Well, the CE is an EGR code and 14 is the CTP switch...so, you have to go test them , as I recommended..there is no magic wand or they do not go away with a simple code clear.
I posted to get the codes from 14 a week ago for your and your responce was you didn't have a pin 14 connection..well, now we know you do.
Do the test and then you will have info that will determine the faults and the remedies...
The Search Feature has all the EGR info a guy could ask for.
I posted one for you..now you have to test it.
The logic behind my test are so you do not think that an EGR code means you need an EGR valve...you can put one in, but I will see you right back with the same code in a few days... an egr code means the egr SYSTEM is mal-functioning, due to one of many, many possible reasons,,,do the test I recommended and I will then use those results and that info to advise you on the proper diagnosis. or just use the search feature ..it is right there..from the test, thru to the remedies ..many times over....
