Resistance inspection
NOTE:
- The MAP sensor and IAT sensor No. 2 cannot be removed as a single unit. When replacing the IAT sensor No. 2, replace the MAP sensor/IAT sensor No. 2.
- Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .)
- 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.
- If not as specified, replace the MAP sensor/IAT sensor No. 2. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO. 2 REMOVAL/INSTALLATION .)
