Intake Sensor Circuit

EJS001GW

COMPONENT DESCRIPTION

Intake Sensor

The intake sensor is located on the heater and cooling unit. It con-

verts temperature of air after it passes through the evaporator into a

resistance value which is then input to the A/C control unit.

After disconnecting intake sensor harness connector, measure resis-

tance between terminals 1 and 2 at sensor harness side, using the

table below.

If NG, replace intake sensor.

DIAGNOSTIC PROCEDURE

SYMPTOM: Intake sensor circuit is open or shorted.

1. CHECK INTAKE SENSOR CIRCUIT BETWEEN INTAKE SENSOR AND BODY GROUND

Disconnect intake sensor harness connector.

OK or NG

OK >> GO TO 2.

NG >> Repair harness or connector.
