I have a 2000 Ford Taurus with ck. engine light on and showing #1405, how can it be fixed?

Question

My mechanic replaced A SENSOR and valve combination on a hose coming from the fuel cap opening and also put in a new fuel filter. He took light off but after 20 mins. of driving it came back on. What next???

This code is a problem with the EGR system, mainly the dpfe sensor. In most cases replacing the sensor will solve the problem. Here is some more info for you.
