P1406 Trouble Code
I have an E-150, 5.4L, 1999, 106000 miles. The 1409 code came on. I replaced the BPFE sensor based on input from others with the same code. I now have code P1000 and P1406 (Downstream BPFE hose not connected). Does anyone have any experience with these codes? Any suggestions. I have checked the lines, reconnected to make sure there is a good seal. Open to suggestions. Thanks.
