P1400 Differential Pressure Feedback Electronic Sensor circuit Low Voltage
So I popped a CEL and am getting code P1400 Differential Pressure Feedback Electronic Sensor circuit Low Voltage. Some one on a general racing forum gave me this:
'p1400 is DPFE low voltage... meaning the sensor is sending lower voltage than normally to the PCM at idle....
DPFEs are known for issues on Ford's... Ford has a few bulletins on the one in your explorer in fact.... Don't come cheap but the parts guy at the Ford dealer (Only place to get yours Sorry) will know all about this gem....
Ford base number is 9J460'
Does anyone know this to be true on the 4.0L? I would like to try to find the TSB(s) on it if they are out there. Does anyone happen to know where Ford stores the Ford truck TSBs? I know that Hyundai stores thiers online and wounder if Ford does the same.
What is the fix?
