Gents,

Have been :banghead for the past month on this EGR valve situation. Replaced all of the vacuum lines on the truck and now the EVR solenoid is showing bad during KOEO. I am unable to find the solenoid on-line. Is this a stealership only item?? If someone has a source, please let me know.

Thanks,

NineT3

What code were you getting from the KOEO?
I am trying to track down my EGR problem and am
now getting code 33, I think because of a bad EVR solenoid.
Thanks

KOEO Codes

Bronco#3,

I am getting 558 - EVR solenoid and 332 - EGR flow insufficient. They sort of follow one another, if the solenoid fails, the EGR valve will not open and the flow will be below specifications.

Later,

Thanks all,
Cleaned my EVR solenoid and checked its operation---all ok.
The cause of my problem was one on the nuts holding the EVP to
the top of the EGR valve was missing causing a vacuum leak.
New nut--goodbye code.
