Hi guys. I have an 01 Explorer Sportrac with a 4.0, 105,000 milles. Got the check engine light with the EGR low flow code. I get this code about once a year and a new DPFE usually takes care of it. I get the sensor from Advanced Auto which explains the short life I am guessing. Last time i replaced the sensor the light came back on a couple weeks later. after highway driving smoke starts pouring fron under the hood, passanger side, but by the time I get the hood opened its done. Cant tell where it is coming from. Could a faulty DPFE cause the smoke or do you think the EGR valve may be sticking? I was going to try a Ford DPFE this time but I hate to just throw parts at it. Where do you thinkk the smoke is coming out of, air filter box????? cant see anything else over there related to the EGR system......

 

With regards the smoke, check/clean/replace the PCV....... Philip

 

where is the pcv valve located on this engine. I looked real quick but didnt notice it.

 

On an '01 it depends on if it's a Job1 or a Job 2 motor. Job 2 oil filler is on the passenger side, Job 1 is on the drivers side.

Job 1

Job 2

Non- FORD/MOTORCRAFT dpfe's have a high failure rate. Try one and you'll see.

 

Thanks, I replaced the DPFE and EGR flow regulator. Also cleaned the PCV valve. Check engine light is out and no under hood smoke for one week. Hopefully problem is resolved. I also forgot to post that the code was a P0401.....low EGR flow.
