Intake Air Temperature (IAT) Sensor
Sensor is located in upper intake manifold. With sensor disconnected, measure resistance between sensor terminals. Refer to the IAT SENSOR RESISTANCE table. Replace sensor as necessary.
IAT SENSOR RESISTANCE
| Temperature | Ohms |
|---|---|
| 68°F (20°C) | 2200-2700 |
| 176°F (80°C) | 290-340 |
