My 2002 Explorer XLT has a service engine light and when it is diagnosed it shows the code P1400 which is the EGR valve. Can this be cleaned or is it best to replace it?
 






You might try cleaning it-but also check the DPFE sensor and the 2 hoses going from the egr tube-to it for leaks and cracks
removal of the dpfe might show it is blown out. You might also check the vacuum lines for the egr valve, and the electrical connection on the egr vacuum solenoid ( regulator)

Good luck, and keep us posted.
