DTC/CIRCUIT DIAGNOSIS

AMBIENT SENSOR

Description

INFOID:0000000009950979

COMPONENT DESCRIPTION 

• The ambient sensor (1) is installed on the middle of radiator upper

support. 

• The ambient sensor converts the ambient temperature detected

with thermistor into the voltage, and the A/C auto amp. inputs this
voltage. 

AMBIENT TEMPERATURE CORRECTION

• The A/C auto amp. inputs the temperature detected with the ambient sensor as the ambient temperature. 
• Perform the correction of the temperature detected with the ambient sensor for air conditioner control and for

ambient temperature display. 

• Since the engine heat influences on the ambient sensor during idling condition, the A/C auto amp. retards

the ambient temperature indication of the combination meter to avoid the effect of steep temperature
change.

• Select and use the initial value of ambient temperature data depending on the coolant temperature when

turning the ignition switch from OFF to ON. Use the detection temperature of the ambient sensor at low cool-
ant temperature [less than approximately 56

°

C (133

°

F)]. Use the memory data (before the ignition switch is

OFF) when the engine is warming up [approximately 56

°

C (133

°

F) or more]. 

• Do not perform the correction of the ambient temperature when the detection temperature of the ambient

temperature is less than approximately 

20

°

C (–4

°

F). 

SET TEMPERATURE CORRECTION

The A/C auto amp. performs the correction to the target temperature set by the temperature control switch so
as to match the temperature felt by the passengers depending on the ambient temperature detected with the
ambient sensor and controls it so that the interior air temperature is always the most suitable. 

Diagnosis Procedure

INFOID:0000000009950980

1.

CHECK AMBIENT SENSOR POWER SUPPLY CIRCUIT

1.

Turn the ignition switch OFF.

2.

Disconnect the ambient sensor connector. 

3.

Turn the ignition switch ON.

4.

Check voltage between ambient sensor harness connector and the ground. 

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> GO TO 4.

2.

CHECK AMBIENT SENSOR GROUND CIRCUIT CONTINUITY 

1.

Turn the ignition switch OFF.

2.

Disconnect the A/C auto amp. connector. 

3.

Check continuity between ambient sensor harness connector and A/C auto amp harness connector.
