I have been doing alot of research and diagnosing on my truck for the 337 code. I have found the DPFE Sensor is putting out almost 5v constant on the signal wire and of course 5v on the bottom wire. I am curious since this is bad could this cause bad MPG? On all highway driving I'm only getting 20MPG. I would thing that 2.3L 5 Speed Manual would do a little better than that on the highway. Let me know what you think.

Thanks in advance!

This isn't gramhar skool so dont cry and whine about spelling.

That sensor is in tune with the EGR which deals with emissions so yes it can
