It's on the drivers side of the engine, on top, right behind the throttle body. Its bolted to the upper plenum, has a four wire connector (I believe), and is round in shape.

Erg flow insufficient


  • The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced
  • There is a blockage in the EGR (tube), most likely carbon buildup
  • The EGR valve is faulty
  • The EGR valve may not be opening due to a lack of vaccuum
It is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit.
  • Use a vacuum pump and pull the EGR valve open while monitoring engine RPM's & DPFE voltage. There should be a noticable difference in RPM's with the EGR open
  • Clean out the EGR valve and/or tubing to remove deposits
  • Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model)
  • Replace the DPFE sensor (with a good quality / OEM one)
  • Replace the EGR valve
The EGR valve is located in the engine compartment. Its should look this

Per Auto Zone, the EGR value needs to be replaced (check engine light is on). Where is the value located and should I try to remove it and clean it? Is there any other items suspect for replacement with...


The EGR valve is located on the intake manifold, it has a single vacuum line going to it, are you sure it is the valve and not the vacuum control valve that opens and closes the EGR? You provided no year or trouble code, so hope this answer is correct.
