A code of p1400 means that there is an EGR fault in the egr system.These systems are basic and contain most of the same parts.These parts are as follows An EGR valve,Egr valve gasket and an ,Egr valve to manifold tube.I would take a look at the gaskets for the manifold tubes and the EGR valve.I cant tell you where its at without knowing the year ,model,and engine size.But with the information given thats the best I can do for you but this gives you some idea as to where to start.

gadiame: The code P1400 is for the EGR valve and Evap canister purge control solenoid valve circuit.
An improper voltage signal is being sent to the ECM through the solenoid valve.
As far as whether the engine using a timing belt or gear? You mean chain? This engine uses a timing chain.
If I can answer any other questions, write me.

This may have to do with a bad wiring. Check all the wiring associated with EGR operation. Whenever a computer throws a code about high or low circuit voltage, it is usually attributed to abnormal wiring.
SOURCE: wat does code p1400 means
The code P1400 reads "DPFE Sensor Voltage Low" (Ford, Mazda). Often it's caused by a bad DPFE sensor or clogged EGR passages. DPFE stands for (Differential Pressure Feedback EGRI) I would clean the EGR valve which cost nothing. If that does not cure the problem, you may need to replace the DPFE sensor, which does cost, and it may not fix the problem. If you want to be sure you replace the correct part, then visit your local Ford dealer.

P1400 - EGRC Solenoid Valve
The P1400 code is for the EGR solenoid and not for the valve. The
solenoid control the opening and closing of the valve. You should check
the solenoid hoses and the connector. Also check if there is voltage at
the green/yellow wire.
Hope helps.
