Question about 2003 Lincoln LS
Help! I'm having trouble figuring out what code P1406 means. Something to do with the "Evap system"?
On your LS.
The CODE P1406,
IS Mean: Differential Pressure Feedback egr. problem.
Ok.. Is just the definition for your code.
The DPFEGR.. is a Little BOX. Black Colour.
Is Normally connected to the EGR tube coming from the EXUAST MANIFOLD. with 2 small hoses.
Inspect the Hoses for broken, burn or stuck with carbon.
if you DON'T found nothing wrong.
Replace the DPFEGR. You van get from DEALER.
DON'T get from autoparts because they only offer one
UNIVERSAL. and most cases don't work right.
Ok.. I hope this help to try to fix your car.
Thank you for use fixya..
