STEP 4. Using scan tool (M.U.T.-IIISE), check data list item 10: Mass Airflow Sensor.
(1) Set the vehicle to the continuous idling mode.
(2) Set scan tool (M.U.T.-IIISE) to the data reading mode for item 10, Mass Airflow Sensor.
(3) Warm up the engine.- The standard value should be between 880 and 1,280 millivolts.
- When the engine is revved, the mass airflow rate should increase according to the increase in engine speed.
(4) Turn off the power supply mode of the electric motor switch.
Is the sensor operating properly?
Go to Step 5. Refer to DTC P0102 - Mass Airflow Circuit Low Input , DTC P0103 - Mass Airflow Circuit High Input .
