Intake Air Temperature Sensor
- Sensor is incorporated in airflow sensor assembly inside air filter housing. Disconnect airflow sensor connector. See Fig 1 .
- On all models, measure resistance between terminals No. 4 and 6 of airflow sensor connector (sensor side of connector).
- For specifications, see INTAKE AIR TEMPERATURE SENSOR RESISTANCE table. Replace airflow sensor assembly if air temperature sensor resistance is not within specification.
INTAKE AIR TEMPERATURE SENSOR RESISTANCE
| Temperature °F (°C) | Ohms |
|---|---|
| 32 (0) | 6000 |
| 68 (20) | 2700 |
| 176 (80) | 400 |
NOTE:
Some engines are not equipped with Motor Position Sensor (MPS). MPS may either be a separate unit mounted to throttle body or it may be incorporated in ISC motor assembly, depending upon vehicle application.
