Distributor Spark Vacuum Modulator Valve (DS-VMV)
This valve limits
distributor spark vacuum to a calibrated value until ported vacuum applied to the control port of the DS-VMV is greater than the calibration value. When ported vacuum is greater than the calibration value, the distributor spark vacuum is equal to the ported vacuum signal.
