Resistance inspection

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