2007 Ford Taurus EGR System testing. EGR valve function, flow and pressure sensor (DPFE) testing is shown, focusing on quick tests you can do on these systems to greatly speed up the troubleshooting process. The tests I demonstrate can be applied to any Ford/Lincoln/Mercury vehicle out there that uses this style of EGR/DPFE system. For more info on DPFE sensor testing, I’ve added a link below to the Ford Ranger case study I mentioned in the video.

Engine Performance Diagnostics chapter 24, page 9
