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. (See BATTERY REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].)

2.  Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].)

3.  Remove the oil level gauge pipe. (See OIL PAN REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].)

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

5.  Remove the MAP sensor/boost air temperature sensor. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/BOOST AIR TEMPERATURE SENSOR REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].)

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