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.
