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??
ohh and by the way my escape has 130k miles on it |
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?
