SOURCE: 2003 Lincoln LS code P1406

Hi........
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..

SOURCE: 1992 cadillac Deville OBD code read out and what it means.

E13-Oxygen sensor voltage stays between 0.307 and 0.609 volts for 64 seconds. Engine was at normal operating temperature at a speed over 800 RPM.
E44-Right oxygen sensor was lean for more than 50 seconds when engine was warm and at 800 RPM or greater.
E52-PCM has lost primary battery power.
E58-Pass Key fuel enable was not correct.
F47-PCM has received bad data from IPC for 3 seconds while engine speed was 500 RPM or more for 3 seconds.
F48-EGR open command was given during off idle operation. EGR opening should cause the mixture to be slightly richer because of the low oxygen content of exhaust gas. Vehicle speed was over 35 MPH and engine was warm.
Good luck and hope this helps, keep me posted be glad to answer any questions you may have.

2000 cadillac deville driver side won't open with the key


1) Key turns but dose not unlock door. This means that the rod that goes to the back of the lock has came off. This also means that is the reason door is not unlocking with the remote as it pops the lock rod inside the door which pushes the lock open.
2) Key does not turn lock at all but works passengers side door. This means that the locks has been changed in the door, but that doesn't sound like the problem as you say the remote doesn't open the drivers side door so more than likely the rod has came off the back of the lock
