Intake Air Temperature Sensor

Check resistance between intake air temperature sensor terminals 5 and 6 under the following conditions.

RESISTANCE CHECKING CONDITION

Intake air temperature °C (°F)	Resistance kΩ
25 (77)	1.94 - 2.06

If NG, replace mass air flow sensor (with intake air temperature sensor).
