Intake Air Temperature Sensor Output Voltage Inspection


Intake Air Temperature Sensor Output Voltage Inspection


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.
