Check Engine Codes

Can anyone define the check engine code 1400 on a 2002 Sable w/ a Duratec?

Differential Pressure Feedback Electronic Sensor circuit Low Voltage. DPFE sensors are known to fail on fords they updated them late 2002 with a plastic unit that doesnt break so easy it seems. I replace a few a month on our fleet vehicles. I manage 150+ at our branch alone.
DPFE should be at .3 to 1.3 volts with no vacume
vacumme applied above 13 pounds or so should be above 4 or so
voltage should drop below 2.5 within 2 secs when u release vacumme.

if your vehicle has under 60,000 miles email me your 17 digit vin and I can tell you if ford will replace the part for free under a warantee extetion that is currently offered on most ford vehicles

I'd be interested in seeing if my Sable is covered under the extended warranty. VIN is 1MEFM55S51A604224

Thanks, bobossman

you have an extention for 2years/24months beyond bumper to bumper warranty

I have a 2000 Sable with P0401, EGR Flow Insufficient. Car has 71K miles and the VIN is: 1MEFM55S1YG628074

Can anyone tell me if this car is covered under the warranty extension?

you had the extention but it has expired by mileage - you do however have a recall 04S17 open to have spring shields installed on the front to protect against tire blowout when the springs break - and trust me they do break
