Description and operation
| Description |
Ambient Temperature Sensor (ATS) is installed on the front-end module and senses the ambient temperature. ECM receives not only the intake air temperatue but also the ambient air temperature informations at the same time to control the intake air quantity precisely provided through the turbo charger. The electrical resistance of the thermistor decreases as the temperature increases, and increases as the temperature decreases This sensor has a Negative Temperature Coefficient (NTC) and its resistance is in inverse proportion to the temperature.
Repair procedures
| Inspection |
| 1. |
Turn the ignition switch OFF. |
| 2. |
Disconnect the ATS connector. |
| 3. |
Measure resistance between the ATS terminals 1 and 2. |
| 4. |
Check that the resistance is within the specification.
|
| Removal & Installation |
| 1. |
Turn the ignition switch OFF and disconnect the battery (-) terminal. |
| 2. |
Remove the engine room under cover. (Refer to Engine Mechanical System - " Engine Room Under Cover") |
| 3. |
Disconnect the connector and then remove the ambient temperature sensor (A).
|
| 4. |
Install in the reverse order of removal.
