Intake Air Temperature Sensor (ATS): Notes

The Intake Air Temperature Sensor (ATS) located on the intake manifold is a resistor-based sensor for detecting the intake air temperature. According to the intake air temperature information from the sensor, the ECM provides necessary fuel injection amount control.
