Resistance inspection
NOTE:
- The IAT sensor No. 2 is built into the MAP sensor. When replacing the IAT sensor No. 2, replace the MAP sensor/IAT sensor No. 2.
- Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION ).
- Remove the following parts:
- Wiper arm (See WIPER ARM AND BLADE REMOVAL/INSTALLATION ).
- Cowl grille (See COWL GRILLE REMOVAL/INSTALLATION ).
- Front suspension tower bar (Vehicles with front suspension tower bar) (See FRONT SUSPENSION TOWER BAR REMOVAL/INSTALLATION ).
- Air box complete (See AIR BOX COMPLETE REMOVAL/INSTALLATION ).
- Disconnect the MAP sensor/IAT sensor No. 2 connector.
- Remove the screw. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO. 2 REMOVAL/INSTALLATION ).
- 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 ).
