Description and operation
Mounted inside the Manifold Absolute Pressure Sensor, Intake Air Temperature
Sensor (IATS) detects the intake air temperature.
To precisely calculate the amount of air, correction of the air temperature is
required as the air density varies with the temperature. So the ECM uses not only
MAPS signal but also IATS signal. This sensor has a Negative Temperature Coefficient
(NTC) thermistor with resistance in reverse proportion to the temperature.

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

Rain and wet roads can make driving dangerous, especially if you’re not prepared
for the slick pavement. Here are a few things to consider when driving in the rain:
A heavy rainfall will make it harder to see and will increase the distance
needed to stop your vehicle, so slow down.
