Differential Pressure Feedback Electronic Sensor circuit Upstream Hose
P1405 Ford - DPFE Sensor Circuit Upstream HoseProbably caused by Faulty DPFE sensor (EGR pressure sensor), or a plugged EGR tube
P1403 is EGR solenoid #1 Error. P1405 is EGR solenoid #3 Error. This means the EGR valve is sticking open or sticking shut. It will need to be removed and cleaned.
The code P1405 on a Ford means: PFE Sensor Circuit Upstream Hose. This code is usually caused by a faulty engine light.
I noticed that question has already been correctly answered by Jrc405 on page 5 of the Ford Ranger XL Q & A
this code is for a error in idle air control
usually that code is a hose off or cracked
P0340 is error code for Camshaft Postion Sensor Circuit Malfunction
Trouble code P0701 means: Transmission control system,range or performance problem
Upstream Oxygen Sensor Circuit Slow Response (Bank 1)
A "bug" is another word for an error. This usually arises if their is a problem with the code or a code's result.
See the forum in the link below.
Trouble code P0400 means: EGR System Performance
