Checking the technical condition
1. Turn off the ignition.
2. Disconnect connectors 1 or 2 of the sensor.
3. Measure the resistance between the IATS signal output and the «masses» sensor.
4. Check that the resistance is within specification.
Withdrawal
Intake air temperature sensor 1 (IATS)
1. Turn the ignition key to position «OFF» and disconnect the negative (-) battery wire.
2. Disconnect the connector (A) intake air temperature sensor 1 and remove the clamp (IN).
3. Turn away fixing bolts and remove the gauge 1 of intake air temperature.
Intake air temperature sensor 2 (IATS)
1. Turn the ignition key to position «OFF» and disconnect the negative (-) battery wire.
2. Disconnect connector and remove sensor 2 (A) intake air temperature.
Installation
Attention.
- Tighten the component mounting bolts to the correct torque.
- Be careful not to drop the component. In the event of a drop, the component must be carefully checked before installation.
Installation is carried out in the reverse order of removal.
Note:
- Bolt of fastening of the gauge of 1 temperature of soaked-up air (IATS): 3.9 - 5.9 Nm.
- Screw of fastening of a collar of the gauge 1 of temperature of the taken-in air (IATS): 2.9-4.9 Nm.
- Mounting for intake air temperature sensor 2 (IATS): 19.6-29.4 Nm.
Replacement
Attention. After replacing the intake air temperature sensor 1, follow the procedure «Component Change Routine» (Component replacement program). Otherwise, a malfunction related to engine characteristics or exhaust control may occur and remain until the data on the new component is registered in the engine control unit.
1. Turn off the ignition.
2. Connect the diagnostic system scanner (GDS) to the diagnostic socket (DLC).
3. Turn on the ignition.
4. Select «Vehicle, Model year, Engine, System» (car, model year, engine, system).
5. Select «Vehicle S/W Management» (Vehicle software control).
6. Select «Component Change Routine» (Component replacement program).
7. Select "INTAKE AIR TEMPERATURE SENSOR CHANGE" (Replacing the intake air temperature sensor).
8. Follow the procedure as instructed on the screen.
