Explorer 5.0 DPFE Sensor Location
I have a replacement DPFE, and I'm ready to get rid of the pesky MIL
indicator (check engine light) so I can get my '97 Explorer inspected and avoid paying the NC government $250 for emissions issues. :-) PROBLEM: Can't locate the darned thing on the engine. There's a beautiful picture of the location on a 4.0L V-6 in a thread here, and I found a diagram on the web that shows the 4.0 installation, but NOBODY seems to have a diagram, picture, or any specific instructions for how to locate or replace this puppy on a 5.0. Even my shop manual doesn't address the 5.0 location or replacement procedures. How about something like, "Remove the intake manifold..." if that's required, and if someone actually performs this procedure and takes a picture, judging from all the posts I've seen on the web, you might be able to retire off the earnings if you just post some clear information on this. :-) |

Right behind the 5 on top of your intake manifold, in back. To the right
of the EGR valve when looking at the engine from the front. All you can see is some of the top of the thing. |

Hmmm. Found the answer, after quite a bit of research on ALLDATADIY.
There is no DPFE on this one. Early models (and this one is known to be one of the first V-8s built) have an EVR (Electronic Vacuum Regulator) system, with the EVR in line with the vacuum to the EGR and receiving its signal directly from the PCM. Later models have the DPFE system, to detect pressure difference between the exhaust and intake, feed the pressure signal to the PCM, which controls the EGR through the EVR. So for those that can't find the DPFE - don't wig out - it's really not there. You can tell by the type of EGR valve that you have, I believe, whether or not you should find a DPFE sensor. -- Eric Message posted via http://www.carkb.com |

I also have a 5.0L (V8) 97' Explorer and my check engine light comes and
goes periodically. Could this be a sensor cause I've been told my my Ford authorized dealer that it is. Why do these sensors get knocked off and end up remaining a problem? If anyone knows holla at me! |
