A: Go to next step 

1. Leave the vehicle for 7 hours or more.

   HINT:

   It is necessary leave the vehicle for 7 hours or more to allow conditions similar to the DTC detection conditions.

2. Connect the intelligent tester to the DLC3.
3. Turn the ignition switch to the ON position.
4. Turn the tester ON.
5. Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DATA LIST / PRIMARY / INTAKE AIR.
6. Read the value displayed on the tester.

   OK: 

   The intake air temperature and the outside air temperature are within 10°C (50°F) of each other. 

   HINT:

   Temperature readings on the vehicle's outside temperature gauge (if equipped) are not suitable for comparing to the IAT reading. The outside temperature gauge has a significant delay built in to prevent temperature swings from being displayed on its display. Use an accurate thermometer to determine the outside air temperature.

NG: REPLACE MASS AIR FLOW METER  (See REMOVAL )
