My wifes eclipse has code P1400 reoccurring even after replacing pres differential sensor (from auto zone). I also checked EGR and vacuum lines, all good. My scanner shows engine load data which fluctuates normally I would say, though not positive about that. I don't see any other data stream to watch operation of pressure sensor or circuit. Can you help? All equipment is standard except for Injen air intake which it has had for several years.
have the same problem?
