I have a code on my 4.6L (it is in a 1992 Crown Victoria) which comes up with a 332 trouble code with a probable cause of EGR valve opening not detected. I have checked the EGR valve with a vacuum tester and it seems to open and close okay. Does anyone have a suggestion of what I can do to fix this code?

Any help would be appreciated.

Thanks Again

 

does the vacuum test hold the valve open for a period of time or does it leak out
