Egr insufficient flow


NO YEAR, STATED.
NO ENGINE STATED.
now that makes this hard, no? my only clue is the body shell.

why not post the DTC error , not your interpretations?
on newer cars there are up to 5 or more EGR DTCs.
the exact dtc or the lack of some , tell the FULL STORY.
for example on newer cars there is EGR feedback readings.

btw: i own a 04GV and have 100%+ documentation on it and can fix any EGR fail on any car made, sure can. GEN1 , to GEN now.
but need more INFO.

Engine service light


The DPFE (Diferential Pressure Sensor)sensor is usually mounted on the engine and is connected to the pipe that runs from the exhaust manifold to the EGR valve with two rubber hoses. When the sensor goes bad, the Check Engine light comes on and typically sets any or all of teh following fault codes: P0171 & P0174 (lean codes), and/or P0401 (insufficient EGR flow). Nine out of ten times, the fault is not a bad EGR valve or a vacuum leak, but a bad DPFE sensor. A replacement costs about $112 at Ford, or about $48 at an aftermarket auto parts store.I hope this helps.

P0410 Service Engine Soon light


There are many, many resons for the check engine light to come on the dash. Just because a parts store reads the code for a certain system, does not mean to just go ahead and replace the part the code says. Many different things can affect any particular system. Replaceing and EGR- lets say, because of an EGR system code may not fix the problem. Anything from broken wires, computer programming update, to clogged passages, to a bad catalytic converter can cuase an EGR code. Tech JK
