Description and operation
Integrated
in the Manifold Absolute Pressure Sensor, the Intake Air Temperature
Sensor (IATS) detects the intake air temperature.
To
precisely calculate the amount of air, air temperature correction is
needed as air density varies with temperature. So, the ECM uses IATS
signal as well as MAPS signal. It has a Negative Temperature Coefficient
(NTC) Thermistor whose resistance changes in reverse proportion to
temperature.

Repair procedures
| 1. | Turn the ignition switch OFF. |
| 2. | Disconnect the IATS connector. |
| 3. | Measure resistance between the IATS terminals 3 and 4. |
| 4. | Check that the resistance is within the specification.

| •
| Tighten the component to the specified torques. |
| •
| Note
that internal damage may occur when the component is dropped. If the
component has been dropped, inspect if it is damaged before installing. |
| •
| Carefully insert the sensor into the installation hole without damaging it. |
|
| 1. | Install in the reverse order of removal. |
