DPFE Sensor

DPFE Sensor
Hi everyone,
Yesterday the ranger threw a check engine light. It happened to be code P0401 (EGR Flow Insufficient). And at the same time i started to get some problems accelerating; the truck would jump like crazy when accelerating from a stop until it got to higher rpms. My assumption was that this problem was related to the check engine light. So after some research on the forum if found out that the DPFE sensor needed replacing. I replaced it and now the truck accelerates from a stop smooth as silk. The problem is that the check engine light is still on. Could it be the EGR valve keeping it on? Is the light suppose to turn off by itself or am I supposed to clear it? Any help would be greatly appreciated.

if you do have to replace it, make sure you get the updated plastic sensor and not the old aluminum one.
