Circuit Diagram
DescriptionIntake Air Temperature Sensor (IATS) is included inside Manifold Absolute Pressure Sensor and detects the intake air temperature.To calculate precise air quantity, correction of the air temperature is needed because air density varies according to the temperature.
Inspection1.Turn the ignition switch OFF.2.Disconnect the evaporator temperature sensor connector.3.Measure the resistance between terminal "+" and "-" of the evaporator temperature sensor.Specification Evaporator core temperature [°C (°F)] Resistance [KΩ]
DescriptionThe In-car air temperature sensor is built in the heater & A/C control unit.The sensor contains a thermistor which measures the temperature of the inside. The signal decided by the resistance value which changes in accordance with perceived inside temperature, is delivered to heater control unit and according to this signal the contr
