P0132 A/F SENSOR 1
Description INFOID:0000000004780114
The air fuel ratio (A/F) sensor 1 is a planar one-cell limit current sen-
sor. The sensor element of the A/F sensor 1 is composed an elec-
trode layer, which transports ions. It has a heater in the element.
The sensor is capable of precise m easurement = 1, but also in the
lean and rich range. Together with its control electronics, the sensor
outputs a clear, continuous signal throughout a wide range.
The exhaust gas components diffuse through the diffusion layer at
the sensor cell. An electrode layer is applied voltage, and this current
relative oxygen density in lean. Also this current relative hydrocar-
bon density in rich.
Therefore, the A/F sensor 1 is able to indicate air fuel ratio by this
electrode layer of current. In addition, a heater is integrated in the
sensor to ensure the required operating temperature of about 800 °C
(1,472 °F).
DTC Logic INFOID:0000000004780115
DTC DETECTION LOGIC To judge the malfunction, the diagnosis checks that the A/F signal computed by ECM from the A/F sensor 1
signal is not inordinately high.
DTC CONFIRMATION PROCEDURE 1.
PRECONDITIONING
If DTC Confirmation Procedure has been previously conduc ted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10.5 V at idle.
>> GO TO 2. 2.
CHECK A/F SENSOR FUNCTION
With CONSULT-III
1. Start engine and warm it up to normal operating temperature.
2. Select “A/F SEN1 (B1)” in “DAT A MONITOR” mode with CONSULT-III.
3. Check “A/F SEN1 (B1)” indication.
With GST
Follow the procedure “With CONSULT-IIII” above.
Is the indication constantly approx. 5 V? JMBIA0112GB
PBIB3354E
DTC No. Trouble diagnosis name DTC detecting condition Possible Cause
P0132 Air fuel ratio (A/F) sensor 1

CHECK GROUND CONNECTION
1. Turn ignition switch OFF.
2. Check ground connections E15, E24. Refer to EC-125, " Ground Inspection " .
Is the inspection result normal? AABWA0307G B
EC-196< COMPONENT DIAGNOSIS >

P0132 A/F SENSOR 1
YES >> GO TO 2.
NO >> Repair or replace ground connection. 2.
CHECK AIR FUEL RATIO (A/F) SENSOR 1 POWER SUPPLY CIRCUIT
1. Disconnect A/F sensor 1 harness connector.
2. Turn ignition switch ON.
3. Check the voltage between A/F sensor 1 harness connector and
ground.
Is the inspection result normal? YES >> GO TO 4.
NO >> GO TO 3. 3.
DETECT MALFUNCTIONING PART
Check the following.
• Harness connectors E8, F8
• IPDM E/R harness connector E45
• 10 A fuse (No. 54)
• Harness for open or short between A/F sensor 1 and fuse
>> Repair or replace harness or connectors. 4.
CHECK A/F SENSOR 1 INPUT SIGN AL CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between A/F sensor 1 harness connector and ECM harness connector.
4. Check the continuity between A/F sensor 1 harness connector and ground, or ECM harness connector
and ground.
5. Also check harness for short to power.
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair open circuit or short to ground or short to power in harness or connectors. 5.

3. Start engine and keep the engine speed between 3,500 and 4,000 rpm for at least 1 minute under no load.
4. Let engine idle for 1 minute.
5. Open engine hood.
6. Select “HO2S2 (B1) P0139” of “HO2S2” in “DTC WORK SUPPORT” mode with CONSULT-III.
7. Follow the instruction of CONSULT-III. NOTE:
It will take at most 10 minutes until “COMPLETED” is displayed.
8. Touch “SELF-DIAG RESULT”.
Which is displayed on CONSULT-III? OK >> INSPECTION END
NG >> GO TO 4.
CAN NOT BE DIAGNOSED>>GO TO 4. 4.
PERFORM THE RESULT OF DTC CONFIRMATION PROCEDURE
1. Turn ignition switch OFF and leave the vehi cle in a cool place (soak the vehicle).
2. Perform DTC CONFIRMATION PROCEDURE again.
>> GO TO 3. 5.
PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-222, " Component Function Check " .
NOTE:
Use component function check to check the overall func tion of the heated oxygen sensor 2 circuit. During this
check, a 1st trip DTC might not be confirmed.
Is the inspection result normal? YES >> INSPECTION END
NO >> Go to EC-224, " Diagnosis Procedure " .
Component Function Check INFOID:00000000047801321.
PERFORM COMPONENT FUNCTION CHECK-I
Without CONSULT-III
1. Start engine and warm it up to normal operating temperature.
2. Turn ignition switch OFF and wait at least 10 seconds.
3. Start engine and keep the engine speed between 3,500 and 4,000 rpm for at least 1 minute under no load.
4. Let engine idle for 1 minute.
5. Check the voltage between ECM harness connector and ground under the following condition.
