COMPONENT INSPECTION
Ambient Sensor
After disconnecting ambient sensor connector, measure resistance
between terminals 2 and 1 at sensor component side, using the table
below.
If NG, replace ambient sensor.
Intake Sensor Circuit EJS001SY
COMPONENT DESCRIPTION
Intake Sensor
The intake sensor is located on the heater & cooling unit. It converts
temperature of air after it passes through the evaporator into a resis-
tance value which is then input to the front air control
DIAGNOSTIC PROCEDURE FOR INTAKE SENSOR
SYMPTOM: Intake sensor circuit is open or shorted. (56 or 57 is indi-
cated on front air control as a result of conducting Self-diagnosis).
