IAT Sensor
- Remove MAF and IAT sensor, see MAF AND IAT SENSOR REMOVAL AND INSTALLATION .
- Check sensor O-ring (1) for damage and deterioration. Replace if necessary.
- Measure resistance between sensor terminals "1" and "2" while blowing hot air to temperature sensing part (2) of MAF and IAT sensor (3) using hot air drier (4).
If faulty condition is found, replace MAF and IAT sensor, see MAF AND IAT SENSOR REMOVAL AND INSTALLATION .
