Resistance inspection

NOTE:

Because the IAT sensor No. 2 is integrated in the MAP sensor, replacing the IAT sensor No. 2 includes replacement of the MAP sensor/IAT sensor No. 2.

Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION .)
Disconnect the MAP sensor/IAT sensor No. 2 connector.
Remove the MAP sensor/IAT sensor No. 2. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO. 2 REMOVAL/INSTALLATION .)
Measure the resistance between MAP sensor/IAT sensor No. 2 terminals A and B.
