P1405-Differential Pressure Feedback Electronic (DPFE) sensor upstream hose off or plugged - or cracked.

I believe it is on the driver's side of engine about half-way down. also, check all other hoses for damage

Ford has problems with the DPFE sensors that has to do with the EGR. its just a code that points you in the direction of the problem. you could have a bad DPFE or egr or just a simple clogged hose. there should be 2 hoses on these f150s the only way to tell is by checking hoses otherwise you need more tools to check these things. a vacuum test on the DPFE sensor to see if it reacts.

the other code is an O2 sensor code. heater problem. could be different problems or a bad O2 can cause a rich condition cause low fuel mileage and also cause the EGR system to clogg over time.
I dont knwo what else to help you with because its one of those things that just needs to be looked at in person. your best bet is check the DPFE hoses. should be near EGR and look for rubber hoses connecter to a sensor. should have 2 hoses connected to it. Google a pic of one so you knwo what they look like.
Good luck

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).

Code p1405


P1405 FORD - Differential Pressure Feedback Electronic Sensor Circuit Upstream Hose.

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.
