Disconnect the battery for 15 minutes and then reconnect it and road test the Explorer. Then redo the KOEO and KOER self test.

Ok. Lets look at the 326.
Make sure the hoses from the EGR tube on the manifold are connected to the DPFE sensor correctly.
The hose connected to the lower port closest to the exhaust manifold goes to the port on the DPFE sensor closest to the radiator. The hose on the upper port connects to the port closest to the firewall.

Have you replaced the DPFE sensor? The black sensor with the two rubber hoses and the electrical connector?

Only the sensor. No the conector.
Mercury Mechanic: A. Penland, Ford Senior Master Technician, ASE replied 3 years ago
When did you replace it the sensor? It looks like it has been on there for a while.

i put the old one back cas with the new one it has the same issues
Mercury Mechanic: A. Penland, Ford Senior Master Technician, ASE replied 3 years ago
Ok. Did you check the EGR port that is behind the EGR valve where it bolts to the intake. If the port is clogged, you will get this code. The port should be clear and open to allow exhaust gases back into the intake to burn off.

Mercury Mechanic: A. Penland, Ford Senior Master Technician, ASE replied 3 years ago
Apply vacuum to the EGR valve vacuum port while the engine is running at idle and see if the engine tries to stall.
Then make sure there is vacuum going to the EGR Vacuum Solenoid.

Mercury Mechanic: A. Penland, Ford Senior Master Technician, ASE replied 3 years ago
If you apply vacuum to the EGR valve and the engine does not to stall out, then either the EGR ports are clogged or the EGR valve is bad.
