*a	Intake Air Temperature Sensor (Thermistor)

Perform a visual check for any foreign matter on the intake air temperature sensor (thermistor) of the intake mass air flow meter sub-assembly shown in the illustration.

OK:

There is no foreign matter.

If the result is not as specified, clean the intake air temperature sensor (thermistor).

Using an air blow gun, clean the intake air temperature sensor (thermistor) area of the intake mass air flow meter sub-assembly by applying approximately 10 intermittent bursts of air to the intake air temperature sensor (thermistor) area at a pressure of approximately 392 to 981 kPa (4.0 to 10.0 kgf/cm², 57 to 142 psi).

HINT:

After performing cleaning, check the intake air temperature sensor (thermistor) resistance.
