I have a 1995 Ford Ranger with 205,000 miles and the check engine light came on with the code for “EGR Valve - Insufficient Flow”. Anyway, I replaced the EGR valve for $80.00 and the light is still on. The truck runs a hell of a lot smoother now with a little more power to boot. Why is the light still on? What else could be causing the “insufficient flow”?

The EGR valve is opened by a Vacuum Solenoid Switch which is opened by current from the computer. If the VSS isn't opening, it won't allow enough vacuum to open the EGR valve. You could also have a vacuum leak, but with 205,000 miles, you could have oil/ carbon build up in the intake, preventing sufficient vacuum to the EGR valve. One other possibility is that the EGR position sensor/ DPFE is sending an incorrect signal to the ECU.

It is supposed to reset on drive cycles, usually at around 50 or 100 miles. If you've driven at least 200 miles since the repairs, you may want to have a diagnostic run again. It could be a loose gas cap, a bad oxygen sensor, or one of several other problems because the check engine light denotes raised emissions.

I had a similar problem with my Ford Escort wagon and after I fixed the problem the light was still on. I went and found a mechanic with those computer diagnostic machines and "rebooted" the internal computer chip of the car. All is well now.

thats true it will fail smog. if you had the code it would have been easier to answer... so who knows if there is another way to fix it or what it is... you can also visit other shops like aamco or even a shop that works just on ford vehicles but is not the dealer. look online for shops near you. some might even diagnose for free as long as repairs are done with them something the dealer wont do

It is possible the computer needs reset. Another possibility is that the internal passages are plugged with carbon. I've had a few cars where I had to take the intake off and clear out the gunk to get the passages opened up.

It could also be the type of fuel you are burning. Check the owners manual for the rating you are supposed to run. My crown vic did the same thing. When I used a higher octane fuel it never did it again.

Maybe your check engine light sensor isn't working properly.
