Inspection [11/2021 - ]: Procedure
- INSPECT MASS AIR FLOW METER
- Perform a visual check for any foreign matter on the intake air temperature sensor (thermistor) of the mass air flow meter shown in the illustration.
*a Intake Air Temperature Sensor (Thermistor) OK
There is no foreign matter.
If the result is not as specified, replace the mass air flow meter.
- Check the intake air temperature sensor (thermistor) resistance.
- Gradually increase the temperature and measure the resistance between terminals when the temperature is 20°C (68°F) and 60°C (140°F).
