DPFE Hose; Check Engine

Hey guys,

While driving around today my check engine light came on. I thoroughly checked the vehicle out and it is functioning properly. I ran the computer and it read a P1405, DPFE Hose.

Could anyone give me any recommendations about how to resolve this problem? I know this is emissions related and shouldn't be a big fix, just want to know exactly what I'm looking for so I can inspect the sensors and the hose before I go out and buy a new part.

I finally got around to taking a closer look at this. After finally finding the DPFE I found one of the hoses was detached from the sensor, plugged it back in and reset the battery. Truck started up and the engine sounds a lot better now, plus the check engine light came off so I can pass my inspection.... hopefully.

I had some issues locating the part and wanted to share with anyone else where to find the sensor. It is front and center closest to the front of the engine compartment on the intake manifold. The 2 hoses travel down to the driver side headers. The key for me finding it was the electrical connection has 3 wires on it.

Here is a photo of the after market plastic sensor on my truck
