Manifold Pressure/Vacuum Sensor



Pressure Sensor, Intake Manifold (431)















Measurement range: 15-235 kPa

The pressure given in kPa denotes the absolute pressure, i.e. 100kPa is equivalent to atmospheric pressure at sea level.

When checking the pressure sensor with a pressure/vacuum pump a lower voltage reading may be obtained at high altitude.
