P1401 is DPFE sensor circuit high, check out this tutorial to replace the sensor on your Ford
P1401 is DPFE Sensor Circuit High Faulty Differential Pressure Feedback Electronic (DPFE) sensor. Loose of disconnected wiring to the sensor
On the ( 4.0 liter EFI , V6 engine ) the DPFE is on the upper intake manifold on the drivers side of the engine
Ford is the only American car company that uses a DPFE sensor. GM dpfe sensor are built into the EGR.
On my 2000 Ranger it was sitting on top, easy to get to. There is a tube that runs from the exhaust manifold to the intake manifold, on that tube is two tubes that run to the EGR(DPFE) pressure sensor(I think that is what you mean). Follow the two tubes to the pressure sensor. Hope this helps!
On the 4.0 L - OHV engine , the DPFE sensor is on the drivers side of the engine , mounted below the idle air control valve
I dont believe the Impala 2003 uses a DPFE sensor as part of there Emissions system.
