How to test EGR Valve?
#1
![Default](/forum/images/icons/icon1.gif)
I removed the egr valve on my 97 XJ6 because of CEL code - P0400. Valve was definitely gunked solid in the closed position but was easily cleaned and moves freely. Re-installed with the hope CEL would go out after a few complete driving cycles - it has not.
Is it possible to apply 12 volts to any of the terminals on the valve to manually listen for a click or some way to see if the valve works at all.
Thanks.
