3-36 FUEL SYSTEM (DFI)
Inlet Air Temperature Sensor (Service Code/Character-13/AIrt)
Inlet Air Temperature Removal/Installation
CAUTION
Never drop the sensor, especially on a hard surface.
Such a shock to the sensor can damage it.
•
Remove the air filter (see Air Filter Removal).
•
Disconnect the connector [A] from the inlet air tempera-
ture sensor.
•
Remove the inlet air temperature sensor [B] and washer.
•
Install the inlet air temperature sensor and washer [A].
•
Tighten:

14 ft·lb)
Output Voltage Inspection
NOTE
○
Be sure the battery is fully charged.
•
Remove the ECU (see ECU Removal). Do not disconnect
the ECU connector.
•

Inlet Air Temperature Sensor Output Voltage
Connections to ECU Connector
Meter (+) → R/BL lead (terminal 7)
Meter (–) → BK/W lead (terminal 8)
•
Turn the ignition switch ON and push the lanyard key un-
der the stop button.
•
Pushing the start button, run the engine 5 ∼ 6 seconds at
idling to measure the sensor output voltage.
○
Wait 15 seconds before using the starter again.
Output Voltage at ECU
Standard: about 2.3 ∼ 2.6 V at inlet air temperature
20°C (68°F)
NOTE
○
The output voltage changes according to the inlet air
temperature.
•
Turn the ignition switch OFF.
