EVR Control Circuit Malfunction
"The test fails when the EGRVR circuit voltage is either too high or too low when compared to the expected voltage range.
The following code can have the following reasons: P040311 P040312 P040472 P040473 P14022F P140216 P140217 P140977 (EGR)
control circuit - circuit short to ground (EGR) control circuit - circuit short to battery (EGR) control circuit range/performance - actuator stuck open (EGR) control circuit range/performance - actuator stuck closed (EGR) control valve metering orifice restricted - signal erratic (EGR) control valve - circuit voltage below threshold (EGR) control valve - circuit voltage above threshold (EGR) control valve vacuum regulator solenoid circuit - commanded position not reachable circuit to ground circuit to power actuator circuit: open circuit fault circuit to ground fault circuit to power fault actuator circuit fault fault actuator circuit fault fault circuit: open circuit ground power EGR valve fault circuit: open circuit ground EGR valve fault power EGR valve fault circuit: open circuit ground power EGR valve fault Check the EGR control valve actuator and circuits
P140977 seems to be "EGR vacuum regulator solenoid circuit" on ford vehicules (https://www.oto-hui.com/diendan/threads/ford-transit-bao-loi-p140977-va-p140216.109203/)

"Le contacteur 'pédale d'embrayage' présente un défaut électrique.Il existe un signal pas plausible." as indicated in this page
"P04047 means EGR stuck open" "P0404 is an egr code but like the mass flow code getting it before engine starts is expected, egr flow/position is calculated based on the mass flow and while that sensor value is erroneous the egr can not be set properly."
