Component Testing
WARNING: This page is about a different variant/trim than selected.
- Ignition OFF, disconnect the harness connector at the B75B Mass Air Flow/Intake Air Temperature Sensor.
- Test the IAT sensor by varying the sensor temperature while monitoring the sensor resistance. Compare the readings with the Temperature Versus Resistance (ECT)
. The resistance values should be in range of the table values.
- If not within the specified range, replace the B75B Mass Air Flow/Intake Air Temperature Sensor.
NOTE:
A thermometer can be used to test the sensor off the vehicle.
