EGR Excessive Flow
So I am new to these forums. To start it off I have a 2002 Ford Ranger EDGE 4.0 v6 4x4. Recently my check engine light came on. I took it to the mechanic and it was the EGR Excessive Flow. After this is fixed will my gas millage increase because I do not get that great gas millage.

if the valve is stuck open then you might see a increse in MPG but i dought its stuck open, if it was the truck would not idle and start rough. its probley the exhaust pressure sensor or DPFE
you need a data scanner and a vacuum pump to check for proper operation of the EGR system. the DPFE sensor should be at around 1.00 volts at idle and rise to almost 4.00 volts when the valve is wide open.

The DPFE is really easy to change, only 40 bucks at advance and then take advantage of the 1 year replacement. Mine has gone out the last 3 years each spring, I buy one, then the next year get that one free haha
