Intake Air Pressure Sensor #1 Output Voltage Connections to Adapter: Digital Meter (+) → Y (sensor Y/BL) lead Digital Meter (–) → BK (sensor BR/BK) lead
Output Voltage
Usable Range: DC 3.80 4.20 V at
standard
atmospheric pressure (101.32 kPa,
76 cmHg)
NOTE
The output voltage changes according to local atmospheric pressure.
If the reading is out of the usable range, replace the sensor.
If the reading is within the usable range, remove the ECU and check the wiring for continuity between main harness connector.

Turn the ignition switch to ON.
Measure the intake air pressure sensor #1 output voltage from various vacuum readings, while pulling the handle of the fork oil level gauge.
Check the intake air pressure sensor #1 output voltage, using the following formula and chart.
Suppose: Pg: Vacuum Pressure (Gauge) of Throttle Body Pl: Local Atmospheric Pressure (Absolute) measured by a barometer Pv: Vacuum Pressure (Absolute) of Throttle Body Vv: Sensor Output Voltage (V)
then Pv = Pl – Pg
For example, suppose the following data is obtained: Pg = 8 cmHg (Vacuum Gauge Reading) Pl = 70 cmHg (Barometer Reading) Vv = 3.2 V (Digital Meter Reading)
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, replace the sensor.
If the reading is within the usable range, check the ECU for its ground and power supply (see ECU Power Supply Inspection in the Fuel System (DFI) chapter).
If the ground and power supply are good, replace the ECU (see ECU Removal/Installation in the Fuel System (DFI) chapter).
