Mazda 3 Service Manual / Drivetrain / Transmission/Transaxle / Automatic Transmission Control / Boost Air Temperature Sensor Inspection [Mzr 2.3 Disi Turbo]

Resistance Inspection

NOTE:

Because the boost air temperature sensor is integrated in the MAP sensor, replacing the boost air temperature sensor includes replacement of the MAP sensor/boost air temperature sensor.

1. Remove the battery cover..

2. Disconnect the negative battery cable..

3. Remove the dipstick pipe..

4. Disconnect the MAP sensor/boost air temperature sensor connector.

5. Remove the MAP sensor/boost air temperature sensor..

6. Measure the resistance between MAP sensor/boost air temperature sensor terminals A and B.

If not as specified, replace the MAP sensor/boost air temperature sensor..
