Well the ol' girl decided to throw a fit (a.k.a. the CEL) the other day while I was looking at a project car to possibly buy. Apparently, she doesn't even like me looking at other women!
Anywho, scanned the next day at work and got a P0401 EGR insufficient flow detected. I quick peek at the data stream showed the DPFE readings were skewed, and I manually commanded the EGR valve with the expected/desired result: rough idle borderline on stalling. So great, my DPFE is going south. No problem, the DPFE is a separate sensor, right?
WRONG! Please tell me WHY IN THE WORLD the engineers at Ford decided to integrate the DPFE into the EGR valve on the 4v? ARGH! I refuse to spend $120 on an entire valve when it's just the stupid sensor that needs replacing.
Looks like I'll be living with the random CEL, I suppose at 196k miles it was bound to happen.
