Intake Air Temperature (IAT) Sensor

IAT sensor is part of Mass Airflow (MAF) sensor. Disconnect MAF sensor connector. Using ohmmeter, measure resistance between MAF sensor terminals "C" and "D". See Fig 1 . Resistance should be 2210-2690 ohms. If resistance is not as specified, replace MAF SENSOR.
