P1401 DPF EGR Sensor Circuit High Input
Possible Causes
DPF EGR signal circuit open, or sensor ground circuit open
DPF EGR signal shorted to VREF or to VPWR
DPF EGR sensor is damaged or has failed
PCM has failed
Most likely a bad DPFE sensor. Fords are notorious for this.

Ford has better blue two layer silicone rubber hoses. Some times there different sizes.
