Air Temperature Sensor
Remove air cleaner upper cover. Heat the intake air temperature sensor using heat lamp or heat gun. Using an ohmmeter, check resistance between terminals "THA" and "E2". If resistance is not within specifications shown in MAZDA AIR TEMPERATURE SENSOR SPECIFICATIONS table, replace airflow meter.
