Description and operation
Description

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.

Removal
1.

Switch "OFF" the ignition and disconnect the negative (-) battery terminal.

2.

Remove the engine cover.

(Refer to Engine Mechanical System - "Engine Cover")

3.

Disconnect the intake air temperature sensor connector (A).

4.

Remove the installation bolts (B), and then remove the sensor from the intake manifold.

9.8 - 11.8 N·m (1.0 - 1.2 kgf·m, 7.2 - 8.7 lb·ft)

Installation
  

Install the component to the specified torques.

Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.

Insert the sensor in the installation hole and be careful not to damage it.

1.

Install in the reverse order of removal.
