Differential Pressure Feedback EGR sensor. It outputs a voltage that represents a pressure differential across a fixed orifice in the EGR tube. This voltage is used by the PCM to judge whether actual EGR flow is tracking commanded flow - an OBDII requirement. The DPFE is a high failure rate part but you should also inspect the hoses leading too it because they tend to harden, crack and leak over time.

Yeah I took my truck in because the CEL is on. They said that the DPFE needs to be replaced. Just never heard of it and it sounded a little off to me. so I wanted to make sure it was real and maybe if I can do it my self.
Would this be something I'm looking for?
Duralast / EGR Valve Pressure Sensor
