17-36 SELF-DIAGNOSIS SYSTEM
Intake Air Pressure Sensor #2 (Service Code 16) (DTC P2226, P2227, P2228)
Intake Air Pressure Sensor #2 Output Voltage
Inspection
• Measure   the output voltage at the intake air pressure sen-
  sor #2 in the same way as input voltage inspection, note
 the following.
○Disconnect the intake air pressure sensor #2 connector
 and connect the measuring adapter [A] between these
 connectors.
  Main Harness [B]
  Intake Air Pressure Sensor #2 [C]
  Digital Meter [D]
  Special Tool - Measuring Adapter: 57001-1700

  Intake Air Pressure Sensor #2 Output Voltage
     Connections to Adapter:
         Digital Meter (+) → Y (sensor R/W) 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 the local at-
    mospheric 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.
  Wiring Continuity Inspection
   ECU Connector [A] ←→
      Intake Air Pressure Sensor #2 Connector [B]
          ECU Terminal 57 [C] ←→ Sensor Terminal [D]
          ECU Terminal 16 [E] ←→ Sensor Terminal [F]
  If the wiring is good, check the sensor for various vac-
  uum (see Intake Air Pressure Sensor #1 Output Voltage
  Inspection(17-24)).
