Description and operation

Description

Installed on the front-end module, the Ambient Temperature Sensor (ATS) senses the ambient temperature. ECM receives the intake air temperature and ambient air temperature at the same time to precisely control the intake air quantity supplied through the turbocharger. The electrical resistance of the thermistor decreases as the temperature increases, and vice versa. This sensor has a Negative Temperature Coefficient (NTC) and its resistance is in inverse proportion to the temperature.

Repair procedures

Inspection

1.	Switch "OFF" the ignition.

2.	Disconnect the ATS connector.

3.	Measure resistance between the ATS terminals 1 and 2.

Check that the resistance is within the specification.

Removal

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

2.	Remove the front engine room under cover. (Refer to Engjne Mechanical System - "Engine Room Under Cover")

3.	Disconnect the connector (A) and then remove the ambient temperature sensor (B).

Installation

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

1.	Install in the reverse order of removal.
