That code is related to the DPFE sensor with low voltage.

from Wikianswers: "Dpfe sensor is the delta (differential) pressure feedback egr (exhaust gas recirculation) it monitors the pressure on the egr valve to make sure it is working."

I am not sure where this sensor is located, one of the mechanics here should be able to let you know where to look. I think you can buy them from the local auto parts store.
