So I just scanned my S14 and the OBD2 sensor read P1400, Differential Pressure Feedback EGR Circuit Low Input. I did some research and owners with Maximas were talking about either cleaning the EGR valve or replacing it. Anyone know of how exactly to replace the valve? sorry I am very new to mechanics and not so mechanically literate. :sadwavey:
