What causes P1402 on a Ford?

Carbon-clogged EGR metering orifice Collapsed EGR pressure hose mimicking restriction Carbon-packed EGR passages in the intake Failed EGR valve not opening to create the expected delta DPFE sensor misreading the restriction

How do I fix P1402 on a Ford?

Remove the EGR valve and inspect the metering orifice for carbon Decarbonize the EGR passages in the throttle body and intake Check DPFE hoses for collapse or blockage Command the EGR open and watch DPFE response Clean or replace components until the flow delta returns
