Description and operation
Installed
on the front-end module, the Ambient Temperature Sensor (ATS) senses
the ambient temperature. ECM receives not only the intake air
temperature but also the ambient air temperature values at the same time
to precisely control the intake air amount provided through the turbo
charger. The electrical resistance of the thermistor decreases as the
temperature increases, and vice versa. This sensor has a Negative
Temperature Coefficient (NTC) whose resistance is in inverse proportion
to the temperature.
Repair procedures
| 1. | Turn the ignition switch OFF. |
| 2. | Disconnect the ATS connector. |
| 3. | Measure resistance between the ATS terminals 1 and 2 [B1/S1]. |
| 4. | Check that the resistance is within the specification.
