Output Voltage Inspection
NOTE
○Be sure the battery is fully charged.
○The output voltage changes according to the inlet air
temperature.
• Remove the ECU (see this chapter). Do not disconnect
the ECU connectors.
• Connect a digital voltmeter to the ECU connector, using
needle adapter set.
Special Tool - Needle Adapter Set: 57001–1457
• Measure the sensor output voltage with the engine
stopped and the connector joined.
• Turn the ignition switch ON.
Inlet Air Temperature Sensor Output Voltage
Connections to ECU Connector
Meter (+) → Y lead (terminal 18)
Meter (–) → BR/BK lead (terminal 14)
Standard: about 2.25 ∼ 2.50 V at inlet air temperature
20°C (68°F)
• Turn the ignition switch OFF.
If the output voltage is out of the standard, remove the
fuel tank and check the wiring. And if the output voltage
is 4.8 V, the ECU is normal.
If the output voltage is within the standard, check the ECU
for its ground, and power supply (see ECU section in this
chapter).
If the wiring is good, check the sensor resistance.
• Remove the needle adapter set, and apply silicone
sealant to the seals of the connector for waterproofing.
