The Service Engine Soon light came on and I checked the code and code P1400 was displayed. After a bit of research I found that usually means the DPFE sensor is bad and since it was only $35 and an easy replacement I swapped out the part, following the procedure in the Haynes repair manual.
I reset the code and it stayed off for 3 days / 300 miles and then it came back on.
What else should I look at?
Thanks, Jim
Does it set P1400 when you pull it again? Did you disconnect the negative battery cable for +/- 1/2 hour?

Yep, P1400 again immediately after resetting it. I disconnected the negative battery cable during the repair but haven't tried it since then. Will give that a try Saturday morning.
Thanks, Jim
I disconnected the negative battery cable for 1 hour yesterday and after running a few errands the Service Engine Soon light came back one.
Any more ideas?
Thanks, Jim
Have you taken the EGR system apart to clean it out and inspect the parts ? There is a good chance that you have a plugged up EGR tube.
No, will look at that this weekend - thanks,
Jim
