My 98 PI car keeps getting a "P1400 Differential Pressure Feedback Electronic Sensor circuit Low Voltage" code thrown. Sometimes the SES light is on, sometimes it's not, no matter if the engine is warm, cold, etc... I have a few spare DPFE's laying around. If i clean out the EGR valve it seems to be ok for a few days, but always returns. Should i swap the DPFE and see if that fixes it, or should I wait until the new motor goes in (in 2-3 weeks) and the EGR is deleted?
Thanks!
Dave
