(a) Read the value of Data List item "Mass Air Flow Sensor" using the GTS.
NOTICE:
Perform the inspection of the mass air flow meter sub-assembly while it is installed to the air cleaner cap sub-assembly (installed to the vehicle).
(1) Check and ensure the following conditions:
- Turn off all electrical loads, such as the air conditioning, etc.
- Check that the coolant temperature is 75°C (167°F) or more.
- Put the shift lever in the N position.
(2) Connect the GTS to the DLC3.
(3) Turn the power switch on (IG).
(4) Turn the GTS on.
(5) Put the engine in Inspection Mode (Maintenance Mode).

(b) Clean the mass air flow meter sub-assembly.
NOTICE:
- Do not contact the mass air flow meter sub-assembly with the nozzle of the air blow gun.
- Do not insert the nozzle of the air blow gun into the airflow hole.
| (1) Using an air blow gun, clean the hole of the mass air flow meter sub-assembly by applying approximately 10 intermittent bursts of air to the airflow hole at a pressure of approximately 392 to 981 kPa (4.0 to 10.0 kgf/cm2, 57 to 142 psi). |
