(a) Read the value of Data List item "Mass Air Flow Sensor" using the Techstream.
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 Techstream to the DLC3.
(3) Start the engine.
(4) Turn the Techstream on.
(5) Enter the following menus: Powertrain / Engine / Data List / Mass Air Flow Sensor.
Powertrain > Engine > Data List
(6) According to the display on the Techstream, read the Data List when the engine is running.
Standard Condition
|
Techstream Display |
Condition |
Specified Condition |
|---|---|---|
|
Mass Air Flow Sensor |
Idling (engine warmed up) |
2.6 to 3.7 gm/sec |
|
2000 rpm (without load) |
5.4 to 9.6 gm/sec |
|
|
3000 rpm (without load) |
10.6 to 15.8 gm/sec |
If the result is not as specified, clean the mass air flow meter sub-assembly.
If the result is within the specified range, check the intake air temperature sensor (thermistor) resistance.

2. CLEAN MASS AIR FLOW METER SUB-ASSEMBLY
NOTICE:
If the mass air flow meter sub-assembly is removed and installed 10 times or more, the thread of the hole of the mass air flow meter sub-assembly may be damaged. Therefore, do not loosen the screws of the mass air flow meter sub-assembly.
(a) Remove the air cleaner cap sub-assembly.
(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.

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). HINT: Apply 5 intermittent bursts of air to the airflow hole at 2 locations. |
