Check Engine Light

[skyrex]

I drop the codes and got 5 DTC's: 1) P0171 - Bank 1 too lean, 2) P0174 - Bank 2 too lean, 3) P1400 - Differential pressure feedback. EGR circuit low input,
4) P1405 - Differential pressure feedback sensor, Up stream hose off or plugged.
5) P1407 - Exhaust gas recirculation, no flow detected.

Vehicle - 1995 Mustang V-6, 3.8L. Hoping someone can point me in the right direction.

No hoses or lines are off. Possible that the line to EGR could have gotten switched around.

Any help is appreciated,

Jerry

sounds like a vaccum leak....

the egr valve should have a green hose....

the hoses are plastic and crack/break very easy,,,

for me i find that pulling all hoses out together and check off of the car works best


on the egr their is a metal tube that runs to exhaust manifold,,on that tube you will find two black rubber vaccum hoses,,,they are different sizes...check them for being off or a hole
