WITH INTELLIGENT AIR CONDITIONER SYSTEM : Description

INFOID:0000000003884752

COMPONENT DESCRIPTION

Gas Sensor

The gas sensor (1) is attached on the bumper upper retainer. It
detects smell of exhaust gas and converts it into a duty ratio which is
then input into the A/C auto amp.

Gas Sensor Circuit

SMELL OF EXHAUST GAS INPUT PROCESS

Gas sensor detects ambient atmospheric CO and NO

2

, and converts them to values of resistance. The values

are converted to signals with the gas sensor internal circuit, then auto amp. inputs the signals.
Gas sensor has a construction that detects CO and NO

2

 by gas sensor element from the air intake of the case

through a filter (waterproof sheet). It sends output signals to auto amp. in response to a resistance value con-
version by gas sensor elements. Output signals prevent a smell of exhaust gas from getting into vehicle by
performing corrections according to various driving conditions.

B262A, B262B, B2657, B2658 GAS SENSOR

NOTE:
If DTC is displayed along with DTC U1000 or U1010, first diagnose the DTC U1000 or U1010. Refer to 

HAC-

164, "DTC Logic"

 or 

HAC-165, "DTC Logic"

DTC CONFIRMATION PROCEDURE

1.

CHECK WITH SELF-DIAGNOSIS FUNCTION OF CONSULT-III

1.

Using CONSULT-III, perform “SELF-DIAGNOSIS RESULTS” of HVAC. 

2.

Check if any DTC is displayed in the self-diagnosis results. 

NOTE:
If DTC is displayed along with DTC U1000 or U1010, first diagnose the DTC U1000 or U1010. Refer to 

HAC-

164, "DTC Logic"

 or 

HAC-165, "DTC Logic"

Is DTC “B262A”, “B262B”, “B2657” or “B2658” displayed?

YES

>> Perform trouble diagnosis for the gas sensor. Refer to 

HAC-176, "WITH INTELLIGENT AIR CON-

DITIONER SYSTEM : Diagnosis Procedure"

NO

>> INSPECTION END

WITH INTELLIGENT AIR CONDITIONER SYSTEM : Diagnosis Procedure

INFOID:0000000003884754

1.

ADJUST GAS SENSOR SENSITIVITY AND CLEAN SWITCH INTERLOCKING CHANGE

1.

Turn ignition switch ON.

2.

Adjust the gas sensor sensitivity and clean switch interlocking change. Refer to 

HAC-116, "WITH INTEL-

LIGENT AIR CONDITIONER SYSTEM : Gas Sensor Sensitivity Adjustment Function (With Intelligent Air
Conditioner System)"

 and 

HAC-116, "WITH INTELLIGENT AIR CONDITIONER SYSTEM : Clean Switch

Interlocking Movement Change Function (With Intelligent Air Conditioner System)"

.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> GO TO 2.

2.

CHECK POWER SUPPLY FOR GAS SENSOR 

1.

Turn ignition switch OFF.

2.

Disconnect gas sensor connector.

3.

Turn ignition switch ON.

4.

Check voltage between gas sensor harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>>

Check power supply circuit and 10A fuse (No. 3, located in the fuse block). Refer to 

PG-101,

"Fuse, Connector and Terminal Arrangement"

• If fuse is OK, check harness for open circuit. Repair or replace if necessary.
• If fuse is NG, check harness for short circuit and replace fuse.

3.

CHECK GROUND CIRCUIT FOR GAS SENSOR 

1.

Turn ignition switch OFF.

2.

Check continuity between gas sensor harness connector and ground.
