This code showed up about a week ago. When I have problems I go to this website for the answers. I did some research and I understand that this code shows up for DPFE sensor, however I can't find the darn thing. I own an 02 4.6, 4x4 f150. Two questions 1) Is it possible for the truck not to have one? 2) If not where is this thing? I own a manual and located everything but that sensor.
Any help or comments would be great...

 

drivers side, about level with the plenum. its kinda close to the powersteering res, a little forward from that and more center towards the intake runners. should be on a black bracket with 2 vacuum lines and one harness.
