INTAKE AIR TEMPERATURE SENSOR CHECK
1. Disconnect the air flow sensor connector.
2. Measure resistance between terminals 5 and 6.
Standard value:
2.3 ± 3.0 kΩ (at 20_C)
0.30 ± 0.42 kΩ (at 80_C)
3. Measure resistance while heating the sensor using a hair
drier.
Normal condition:
Temperature (_C) Resistance (kΩ)
Higher Smaller
4. If the value deviates from the standard value or the
resistance remains unchanged, replace the air flow sensor
assembly.
