[mrscullini]

so i searched with not one thread popping up.

i've got an '02 with 145k miles. dtc p0402 has been thrown. i believe this is releated to the egr. any suggestions on what exactly to check?

thanks.

try searching for that code. I am sure it has been brought up once or twice on these forums.

so i searched the other v-6 forums and it could be the valve or the dpfe sensor, which i kind of new from other research. i am looking for some insight specific to the 4 liter. should i start with the valve or the sensor? any other suggestions?

Did you really feel it neccessary to put down the crack pipe and turn down "dark side of the moon" just to tell this guy to do a search...the more I look at these forums the more I realize almost no one gets any help...at least not directly , you would be surprised how little useful info in contained in most replies about specific problems...problems that are known to be endemic in ford rangers...this guy is looking for someone with a 4.0 litre that had the same code pop up that fixed it..period...that's what is truly helpful.
