Please let me know if you can open this. If not, let me know because this is all the info for the fault code that you have. I would post it but it is too large.

If your map sensor is bad, it will also cause p1447 to illuminate.
You can check the air passage continuity on the map sensor/solenoid valve.
Provide the switch with 12 volts, please note which pin is positive and negative.



Check air passage continuity between A-B, A-C. My manual shows that if there is no continuity between A-B but there is between A-C then your map sensor/solenoid valve is bad and should be replaced.
It is listed as a cause for the p1447 light.
I hope this helps

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.

In order to give you accurate information. I need size of engine example 2.0 L 3.0L. but code P1400 means Differential Pressure feedback EGR circuit low input. Maybe your differential oil is low.

p1400 is a egr valve malfunction which will cause misfire
