Intake Air Temperature Sensor
Disconnect airflow sensor connector. Check intake air temperature sensor by measuring resistance between airflow sensor terminals No. 4 (Green/Blue wire on 1.5L and 1.6L; Green/Brown wire on 2.0L and 3.0L) and No. 6 (Black wire). See Fig 1 . Using a hair dryer, warm intake air temperature sensor while watching ohmmeter. Resistance value should change evenly as temperature rises. Replace airflow sensor assembly if resistance is not within specification or values do not change while sensor is warmed. See INTAKE AIR TEMPERATURE SENSOR RESISTANCE table.
INTAKE AIR TEMPERATURE SENSOR RESISTANCE
| Temperature °F (°C) | Ohms |
|---|---|
| 32 (0) | 6000 |
| 68 (20) | 2700 |
| 176 (80) | 400 |
