INTAKE SENSOR

System Description

COMPONENT DESCRIPTION




Intake Sensor
The intake sensor is located on the heater & cooling unit assembly. It converts temperature of air after if passes through the evaporator into a resistance value which is then input to the front air control.

Intake Sensor Diagnosis Procedure

DIAGNOSTIC PROCEDURE FOR INTAKE SENSOR




SYMPTOM: Intake sensor circuit is open or shorted. Using the CONSULT- III, DTC B2581 or B2582 is displayed. Without a CONSULT-III, code 56 or 57 is indicated on front air control as a result of conducting self-diagnosis.

Step 1-2:

Step 3-4:

COMPONENT INSPECTION




Intake Sensor
After disconnecting intake sensor connector, measure resistance between terminals 1 and 2 at sensor harness side, using the table given.

If NG, replace intake sensor.
