Inlet Air Temperature Sensor (Service Code 13)
Never drop the sensor, especially on a hard surface.
Such a shock to the sensor can damage it.
Remove the right air cleaner base (see Right Air Cleaner
Housing Removal in this chapter).
Disconnect the connector [A] from the inlet air tempera-
ture sensor, and unscrew the nut [B].
Remove the inlet air temperature sensor.
Torque - Inlet Air Temperature Sensor Nut: 7.8 N·m (0.80
kgf·m, 69 in·lb)
Output Voltage Inspection
Be sure the battery is fully charged.
The output voltage changes according to the inlet air
Remove the ECU (see this chapter). Do not disconnect
the ECU connectors.
Connect a digital voltmeter [A] to the ECU connector [B],
using two needle adapters [C].
Special Tool - Needle Adapter Set: 57001–1457
Measure the output voltage of the sensor with the engine
stopped and the connector joined.
Turn the ignition SW ON.
Inlet Air Temperature Sensor Output Voltage
Connections to ECU Connector
Meter (+) → P lead (terminal 31)
Meter (−) → BR/BK lead (terminal 11)
Output Voltage at ECU
Turn the ignition SW OFF.
If the output voltage is out of the specified, check the ECU
for its ground, and power supply (see ECU section in this
chapter). If the ground and power supply are good, re-
move the right air cleaner base, check the wiring between
the ECU and the inlet air temperature sensor.
If the wiring is good, check the sensor resistance.
Remove the needle adapters, and apply silicone sealant
to the seals of the connector for waterproofing.
