[bibi719]

im a new at this soo please help me

i have a 2002 ford escape 3.0L
the car was runing good till the EGR valve broke
i cheked the intake manifold and all lines to see if its was clogged up that caused the EGR to break but didnt find anything at all i also checked the exhaust as well but still nothing
sooo..lucky i found and bought another EGR from a junkyard from da same vehicle but wit about 20k miles and replaced it.
now about 5 days later my the EGR broke again

do you guys have any clue what might cause the problem??

Maybe it isn't your EGR valve. There's normally another valve in the EGR system that reads the difference in pressure across the orfice in the ERG tube. It puts out a voltage depending on what it sees. You'd need a DMM, hand vacuum pump and specs/procedure from a manual to troubleshoot it.

What code are you getting? ERG flow at idle?

well i had the light on but it was for the O2 sensors....but now the code that is showing is p1000 but i have no code whatsoever on the EGR i find it weird that the EGR valve just broke out of the blue without any engine light on

What do you mean by "just broke"?

All the P1000 means is that all the OBD-II system monitors haven't been completed yet or really it hasn't been driven enough yet. If you disconnect the battery when you worked on it would cause that P1000 to come up.
