EGR Location / Cleaning
My 2002 explorer Sport Track (50k Miles) now has the check engine light - after having autozone pull the codes it is due to Low / insufficient EGR flow....
Does any one have any pics / proceudres on how to clean it? is it more worth while replacecing it (50.00 or so) or clean it?
Thanks,
Jason.

First and fore most it may not be the EGR. Which engine does it have? The egr is not the only piece of the puzzle. The egr differential sensor can also go bad and give that code. Let me know which engine and I'll try to help.

The egr and DPFE sensor are located on the drivers side of the engine. The egr is toward the front and teh sensor is mounted to the rear of it. One mine it was silver with one wiring connector and two vacuum lines. I understand though that they also came in plastic.
You can check the egr operation by removing the vacuum line at the top and attatching another piece of vacuum line and sucking on the line. With very little vacuum, the egr should open. It can be removed by two bolts and undoing the exhaust connection.
I learned the hard way, replaced the egr and still had the code. I then went to Carquest and bought the DPFE and it took care of it. It was about $80 at Carquest.
Both the egr and DPFE can be cleaned but that doesn't always solve the problem. I would start with the DPFE first, IMO.

Hi Jason,
Here is a URL that has a description, and some electrical tests you can do on the DPFE sensor:
