hello everyone,

2000 camry

Should a vacuum modulator associated with EGR leak during a smoke test?

Depending on how the smoke test is done, the vacuum modulator might leak a small amount only because it's vented to the atmosphere. The following is not a smoke test but with only the year and model given, it might be helpful  https://www.youtube.com/watch?v=Fr3Q4Esxce0
