done that. sensor was removed before it came into shop have no way to know what position connector was in.
before vehicle runs but 340 code
Expert:  Ford expert replied 6 years ago.
did you set the timing marks as it says ? a po340 code is often a bad dpfe sensor ,,Disconnect the electrical connector from the Delta Pressure Feedback Exhaust Gas Recirculation , sensor. This is the flow sensor for the EGR system. It is a rectangular aluminum sensor with a 3-wire connector mounted at the front of the passenger side valve cover. Drive the vehicle, and see if the P0340 or the bucking problem ever occur with the DPFE sensor disconnected. Ignore any EGR or DPFE sensor- related codes. If the problem never occurs with the DPFE sensor disconnected, replace the DPFE sensor with the updated Black plastic sensor
