Main Harness [B] Intake Air Temperature Sensor [C]
Special Tool - Measuring Adapter: 57001-1700
Intake Air Temperature Sensor Output Voltage Connections to Adapter: Digital Meter (+) → R (sensor R/BK) lead Digital Meter (–) → BK (sensor BR/BK) lead
Output Voltage Standard: About DC 2.44 ∼ 2.69 V at 25°C (77°F)
NOTE
The output voltage changes according to the intake air temperature.
If the reading is within the standard, check the ECU for its ground, and power supply (see ECU Power Supply Inspection in the Fuel System (DFI) chapter).
If the ground and power supply are good, replace the ECU (see ECU Removal/Installation in the Fuel System (DFI) chapter).
If the reading is out of the standard, remove the ECU and check the wiring for continuity between main harness connectors.
Special Tool - Hand Tester: 57001-1394
Disconnect the ECU and sensor connectors.
Wiring Inspection ECU Connector [A] ←→ Intake Air Temperature Sensor Connector [B] R/BK lead (ECU terminal 37) [C] BR/BK lead (ECU terminal 13) [D]
If the wiring is good, check the intake air temperature sensor resistance (see Intake Air Temperature Sensor Resistance Inspection).
