FUEL SYSTEM (DFI) 3-59
Intake Air Temperature Sensor (Service Code 13) (DTC P0110, P0112)

• When   only the service code is available, follow all inspec-
  tion procedures in this section.
• When   the DTC (Diagnostic Trouble Code) is available,
  follow inspection procedures that has have the DTC in
    the headline in this section.
Intake Air Temperature Sensor Removal/Instal-
lation
                            NOTICE
    Never drop the intake air temperature sensor espe-
    cially on a hard surface. Such a shock to the sensor
    can damage it.

• Remove:
   Fuel Tank (see Fuel Tank Removal)
     Connector Bracket
•   Disconnect:
     Intake Air Temperature Sensor Connector [A]
•   Remove:
     Intake Air Temperature Sensor Screw [B]
     Intake Air Temperature Sensor [C]

• Be  sure to install the O-ring [A].
• Install the intake air temperature sensor.
• Tighten:
    Torque - Intake Air Temperature Sensor: 1.2 N·m (0.12
                kgf·m, 11 in·lb)
• Connect:
   Intake Air Temperature Sensor Connector
• Install the removed parts (see appropriate chapters).
Intake Air Temperature Sensor Inspection (Service
Code 13/DTC P0110)
(Checking wire for open circuit)
• Disconnect:
   ECU Connectors (see ECU Removal)
   Intake Air Temperature Sensor Connector (see Intake
   Air Temperature Sensor Removal/Installation)
• Check the wiring for continuity between the ECU harness
  connector and sensor connector.
    Wiring Continuity Inspection
     ECU Harness Connector [A] ←→
        Intake Air Temperature Sensor Connector [B]
          R/BK lead (ECU terminal 16) [C]
    If there is no continuity, repair or replace the main har-
    ness.
    If there is continuity, first check the intake air temperature
    sensor wirings (see Intake Air Temperature Sensor Cir-
    cuit).
    If there is no continuity, repair or replace the main har-
    ness.
    If there is continuity, second check the terminals of the
    sensor and ECU for corrosion or bent.
    If the terminals are corroded or bent, replace the intake
    air temperature sensor and/or ECU.
