Description and operation
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
1. |
Switch "OFF" the ignition.
|
2. |
Disconnect the ATS connector.
|
3. |
Measure resistance between the ATS terminals 1 and 2.
|
4. |
Check that the resistance is within the specification.

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).

The power steering uses a motor to assist you in steering the vehicle. If the
engine is off or if the power steering system becomes inoperative, the vehicle may
still be steered, but it will require increased steering effort.
