3-56 FUEL SYSTEM (DFI)
Intake Air Pressure Sensor #1 (Service Code 12) (DTC P0105, P0107)
then
  Pv = 70 – 8 = 62 cmHg (Absolute)
Plot this Pv (62 cmHg) at a point [1] on the chart and draw a
vertical line through the point. Then, you can get the usable
range [2] of the sensor output voltage.
    Usable range = 3.08 ∼3.48 V
Plot Vv (3.2 V) on the vertical line. → Point [3].
Results: In the chart, Vv is within the usable range and
the sensor is normal.
  If the reading is out of the usable range, visually inspect
  the intake air pressure sensor #1 and vacuum hose for
  clogged.
  If the sensor and hose are good, replace the intake air
  pressure sensor #1.
