- Ignition/Vehicle - Off
- Disconnect the electrical connector:B75C Multifunction Intake Air Sensor
- Test for 49 to 49, 882 ohms between the test points:Signal terminal 1 & Low Reference terminal 3
- If not between 49 and 49, 882 ohms
Replace the component:B75C Multifunction Intake Air Sensor
- Go to next step: If between 49 and 49, 882 ohms
- If not between 49 and 49, 882 ohms
- Verify the value is within the range listed in the table:Temperature Versus Resistance - Intake Air Temperature Sensor
- If not in the specified range
Replace the component:B75C Multifunction Intake Air Sensor
- Go to next step: If in the specified range
- If not in the specified range
- Test for infinite resistance between the test points:Each terminal of the component & The component's housing
- If less than infinite resistance
Replace the component:B75C Multifunction Intake Air Sensor
- Go to next step: If infinite resistance
- If less than infinite resistance
- All OK.
