How to clean an egr


Remove the air cleaner outlet tube. Detach the EGR tube (Fig. 1). Disconnect the EGR vacuum tube. Remove the EGR valve (Fig. 2). Remove and discard the EGR valve gasket. To aid instillation, loosen the EGR tube bolts at the exhaust manifold. Install a new EGR valve and gasket.

Code po401


A code P0401 most likely means one or more of the following has happened:
  • 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
Possible SolutionsIn fixing this code, 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'sicon1.png & 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
