WARNING: This page is about a different car, the 2017 Chevrolet Suburban 3500 HD. However, it is still accessible from the selected car via links, so may be relevant.

Multifunction Intake Air Sensor - IAT Sensor 1

  1. Ignition OFF, disconnect the harness connector at the B75C Multifunction Intake Air sensor.
    2. NOTE:

    A thermometer can be used to test the sensor off the vehicle.

  2. Test the IAT sensor 1 by varying the sensor temperature while monitoring the sensor resistance. Compare the readings with the Temperature Versus Resistance - Intake Air Temperature Sensor table for Hitachi Sensors. The resistance values should be in range of the table values.
    • If not within the table values. 

      Replace the B75C Multifunction Intake Air sensor.

    • If within the table values. 
  3. All OK

Multifunction Intake Air Sensor - IAT Sensor 2

  1. Test the IAT Sensor 2 by varying the sensor temperature while monitoring the air temperature with a thermometer. Compare the readings with the scan tool IAT Sensor 2 parameter. The values should be within 5%.
    • If not within 5% 

      Replace the B75C Multifunction Intake Air sensor.

    • If within 5%
