Check the hoses to the DPFE sensor from the exhaust pipe, the sensor is near the EGR valve, if the hoses are ok then replace the sensor, careful not to tear the special heat resistant silicone rubber hoses, they are about $10 each and ordinary rubber hose will burn up.

P1405- Differential pressure feedback sensor upstream hose off or plugged
It has to do with your EGR operation

The Differential feedback pressure sensor is located under the hood on the drivers side.

If you locate your EGR valve you will see a tube going from it to your exhaust manifold.

you will notice 2 small tubes leading from the large one feeding into a small sensor....this is the DPFE sensor which is throwing your code.

Now....the DPFE "could" be doing its job by telling you the orfice in the tube is plugged, but the DPFE is known to fail on these trucks.....but it throws a code P401....

It may be a good idea to try a new DPFE sensor before a new EGR tube.


Hope helps.

P1405 code


DTC P1405 - Differential pressure feedback (DPFE) sensor upstream hose off or plugged
Verify both hoses are connected to the DPFE sensor first. Ford has two versions of the sensor commonly used of this generation of modular engines.

The first uses a pair of flexible hoses to make the connections from the EGR tube to the sensor. The hose may fail and cause this problem.

The second type of DPFE sensor is stalk-mounted. The two tubes from the EGR tube come up to the sensor and the sensor is just pushed down onto the ends of the tubes and is secured with hardware.

Inspect to see which type you have and whether there are any obvious connection failures.

Hope this helps (remember to rating this free answer).

This means either the EGR position sensor hose is pulled off or damaged or the sensor is defective. The sensor is referred to as the EGR (exhaust gas recirculation valve) DPFE sensor.

P1405 DPFE Sensor Upstream Hose Off Or Plugged
This is actually going to be real easy. There is a sensor with 2 rubber hoses. It probably has a hole in it. This is a black sensor with 2 screws to hold it in place.
