Hey everyone, had the cracked elbow a few months back and now my wife's ST had the CEL on again with P1400 in memory. I replaced the DPFE right off the bat since that's the general consensus, but three days later the CEL came back on. I checked for codes and got the same P1400.
There's no EVP (EGR Valve Position) sensor on the ST like earlier OBDI/EEC IV Fords. My guess would be the EVR (EGR Vacuum Regulator) that regulates the flow to the EGR valve.
I double checked all of the vacuum lines and the EGR hoses to the DPFE.
Anyone have any ideas that I can go on?
Thanks...
