17-24 SELF-DIAGNOSIS SYSTEM
Intake Air Pressure Sensor #1 (Service Code 12) (DTC P0105, P0107)
Intake Air Pressure Sensor #1 Output Voltage
Inspection
• Measure   the output voltage at the intake air pressure sen-
  sor in the same way as input voltage inspection, note the
 following.
○Connect the measuring adapter [A] to the intake air pres-
 sure sensor connectors as shown.
  Main Harness [B]
  Intake Air Pressure Sensor #1 [C]
  Digital Meter [D]
  Special Tool - Measuring Adapter: 57001-1700

  Intake Air Pressure Sensor #1 Output Voltage
     Connections to Adapter:
         Digital Meter (+) → Y (sensor R/BK) lead
         Digital Meter (–) → BK (sensor G) lead

• Measure   the output voltage with the engine stopped and
  with the connector joined.
• Turn the ignition switch on.
  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 atmo-
   spheric pressure.

• Turn  the ignition switch off.
  If the reading is out of the usable range, replace the sen-
  sor.
 If the reading is within the usable range, remove the ECU
 and check the wiring for continuity between harness con-
 nectors.
○Disconnect the ECU and sensor connectors.
