Intake Air Temperature Sensor Test
Remove air cleaner cover. Heat intake air temperature sensor and note temperature. See Fig 1 . Using an ohmmeter, check resistance between Black/Light Green wire and Yellow/White wire terminals of intake air temperature sensor. See INTAKE AIR TEMPERATURE SENSOR RESISTANCE table. If resistance is not as specified, replace sensor.
INTAKE AIR TEMPERATURE SENSOR RESISTANCE
| Temperature °F (°C) | Ohms |
|---|---|
| -4 (-20) | 14,600-17,800 |
| 68 (20) | 2200-2700 |
| 176 (80) | 290-350 |
