Fleetwood V8-368 6.0L VIN 9 FI (1982)
Manifold Pressure/Vacuum Sensor: Description and Operation
The MAP sensor supplies a varying DC voltage signal to the ECM representing manifold pressure----usually used in conjunction with a BARO
sensor.
-
When manifold pressure is low (high vacuum), sensor output voltage is low--under 1 volt.
-
When manifold pressure is high (low vacuum), sensor output voltage is high--4.5 volts.
NOTE: Turbocharged models are equipped with a MAP sensor with internal altitude compensation.
