EGR valve.

[jojobaby1973]

I just had both EGR valves changed o my 96 Ford Explorer 4x4..The damn engine light is still on and I cannot pass smog..Just had a tune up on it last week, plugs and wires only..The diagnosis comes up saying EGR valves..But after driving it for 25 miles and turning it off and back on the light comes back on,,GRRR
Can anyone suggest anything???
Thanks~

Welcome to this forum! I've moved your thread into the stock 95-01 section. What are the code numbers? It might be the DPFE sensor, and not the EGR valve.

Welcome. Posting the exact code(s) will be very helpful. Otherwise, it could be a couple different things.

DPFE Sensor

I just replaced my DPFE sensor last week, successfully! That is most likely your problem if your error code is P0402, that's what my reader said. Hope this helps! =)

You only have one EGR valve. Do you mean the EGR & DPFE?

A cracked vaccum line will cause an EGR code. Did the shop replace or check the lines to the DPFE?

I have an on going egr issue as well. The guy read the codes just said hi egr flow... so i figured it was due to a tube. I found one end of the tube cracked so i cut it back, got a good seal but the CEL came back on......... grrrrr..... off to the parts store tomorrow to get the code number..
