should be near intake manifold. The code P1400 reads "DPFE Sensor Voltage Low" 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,
