SELF-DIAGNOSIS SYSTEM 17-23
Intake Air Pressure Sensor #1 (Service Code 12) (DTC P0105, P0107)
Intake Air Pressure Sensor #1 Input Voltage
Inspection
                            NOTE
  ○Be sure the battery is fully charged.
• Turn the ignition switch off.
• Removal(3-54)).
  Remove   the air cleaner housing (see Air Cleaner Housing

• Disconnect  the intake air pressure sensor #1 connector
  and connect the measuring adapter [A] between these
  connectors.
   Main Harness [B]
   Intake Air Pressure Sensor #1 [C]
  Special Tool - Measuring Adapter: 57001-1700
• Connect
  leads.
          a digital meter [D] to the measuring adapter

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

• Measure   the input voltage with the engine stopped and
  with the connector joined.
• Turn the ignition switch on.
  Input Voltage
    Standard: DC 4.75  5.25 V

• Turn   the ignition switch off.
  If the reading is within the standard, check the output volt-
  age (see Intake Air Pressure Sensor #1 Output Voltage
  Inspection(17-24)).
 If the reading is out of the standard, remove the ECU and
 check the wiring for continuity between harness connec-
 tors.
○Disconnect the ECU and sensor connectors.
  Wiring Continuity Inspection
   ECU Connector [A] ←→
      Intake Air Pressure Sensor #1 Connector [B]
        ECU Terminal 22 [C] ←→ Sensor Terminal [D]
        ECU Terminal 16 [E] ←→ Sensor Terminal [F]
  If the wiring is good, check the ECU for its ground and
  power supply (see ECU Power Supply Inspection(3-39)).
  If the ground and power supply are good, replace the
  ECU.
