- Remove MAF & IAT sensor. See MASS AIR FLOW (MAF) & Intake Air Temperature (IAT) Sensor Removal and Installation
- Check sensor O-ring (1) for damage and deterioration. If faulty condition is found, replace MAF & IAT sensor.
- Measure resistance between sensor terminals "1" and "2" while blowing hot air to temperature sensing part (2) of MAF & IAT sensor (3) using hot air drier (4).
If measured resistance is out of specified value, replace MAF & IAT sensor.
Intake air temperature sensor resistance
-20 °C (-4 °F): 13.6 - 18.4 kΩ
20 °C (68 °F): 2.21 - 2.69 kΩ
60 °C (140 °F): 0.493 - 0.667 kΩ
