Century V6-181 3.0L VIN E 2-BBL (1982)
Manifold Pressure/Vacuum Sensor: Description and Operation
Vacuum Sensor
NOTE: If vehicle is not equipped with a MAP sensor, it may be equipped with a vacuum sensor--some systems may not use either.
Sensor produces low voltage--approximately 1 volt--when manifold vacuum is low, and higher voltages-- approximately 4.5 volts --when vacuum is
high.
Normal output is 0.54 - 0.62 volts with ignition ON and engine stopped.
