confused 3.0 EVR (vacuum regulator) not operating

Hi Folks:

I'm trying to pass Cali smog with an 87 Sable 3.0 and the EVR (vacuum regulator) isn't getting it's ground trigger when the r's increase (voltmeter shows 3v constant under all rpm's). Does anyone have an idea what I should check next? Is there another sensor that tells the ECU when this should occur? Thanks very much in advance for your knowledge. Markus
