Issue / Question:
Service engine light came on then off then on then off and has stayed off after 2/3 can of Amsoil PI and a can of Techron In successive gas fill-ups. Trouble code 1406 is stored in computer for differential pressure feedback electronic sensor circuit downstream hose, whatever that is. Is it OK to drive as long as service engine light stays off? Explorer has 60,000 miles on it.

Answer:
DPFE failure is common on these, it recognizes positive EGR pressure.
if its to great it could mean the tube is plugging up or restricted, other times it means the DPFE solenoid is going bad we can scan the system look at the DPFE data and find out what it needs, let us know if we can help 407-629-2661.
