Description and Operation

Description

The ambient air temperature sensor (ATS) is mounted on the front module and measures outside air temperature. The ECM receives information not only on intake air temperature but also on ambient air temperature and intake air volume, which is used for precise turbocharger control. The electrical resistance of the ATS decreases as temperature rises and increases as temperature falls. This sensor has a negative temperature coefficient (NTC); its resistance is inversely proportional to temperature.

TEST

  1. Turn the ignition off.

  2. Disconnect the ATS connector.

  3. Measure the resistance between terminals 1 and 2 of the ATS [B1/S1].

  4. Make sure the resistance is within specification.
