Circuit/System Description
WARNING: This page is about a different car, the 2016 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.
The Bank 2 sensors listed below are integrated within the multifunction intake air sensor:
- IAT sensor 2
- Humidity sensor
- MAF sensor
- BARO pressure sensor
The IAT sensor 2 and the humidity sensor share the same circuit. The IAT sensor 2 signal is displayed by the scan tool as Hertz (Hz) and °C (°F).
IAT Sensor 2 - Temperature, Frequency Table
| IAT Sensor 2 | IAT Sensor 2 Frequency | IAT Sensor 2 Temperature |
|---|---|---|
| Cold | 45 Hz | -40°C (-40°F) |
| Warm | 302 Hz | 104°C (219°F) |
