DTC DETECTION LOGIC

To judge the malfunction, the diagnosis checks that the heated oxy-
gen sensor 1 is not inordinately high.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Start engine and warm it up to normal operating temperature.

2.

Turn ignition switch OFF and wait at least 10 seconds.

3.

Restart engine and let it idle for 2 minutes.

4.

Check 1st trip DTC.

Is 1st trip DTC is detected?

YES

>> Go to 

EC-409, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000005886525

1.

CHECK GROUND CONNECTION

1.

Turn ignition switch OFF.

2.

Check ground connection E38. Refer to Ground Inspection in 

XX-XX, "*****"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace ground connection.

2.

RETIGHTEN HEATED OXYGEN SENSOR 1

Loosen and retighten heated oxygen sensor 1. Refer to 

XX-XX, "*****"

.

>> GO TO 3.

3.

CHECK HO2S1 GROUND CIRCUIT FOR OPEN AND SHORT

1.

Disconnect heated oxygen sensor 1 (HO2S1) harness connector.

2.

Disconnect ECM harness connector.

Trouble diagnosis name

DTC detecting condition

Possible Cause

P0132

Heated oxygen sensor 1 circuit 
high voltage

An excessively high voltage from the sensor 
is sent to ECM.

• Harness or connectors

(The sensor circuit is open or shorted.)

• Heated oxygen sensor 1

3.

Check harness continuity between HO2S1 harness connector and ECM harness connector.

4.

Also check harness for short to ground and short to power.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair open circuit or short to ground or short to power in harness or connectors.

4.

CHECK HO2S1 INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

1.

Check harness continuity between HO2S1 harness connector and ECM harness connector.

2.

Check harness continuity between HO2S1 harness connector or ECM harness connector and ground.

3.

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.

CHECK HO2S1 CONNECTOR FOR WATER

Check heated oxygen sensor 1 connector for water.

Is the inspection result normal?

YES

>> GO TO 6.

NO

>> Repair or replace harness or connectors.

6.

CHECK HEATED OXYGEN SENSOR 1

Refer to 

EC-410, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 7.

NO

>> Replace heated oxygen sensor 1.

7.

CHECK INTERMITTENT INCIDENT

Refer to 

XX-XX, "*****"

.

>> INSPECTION END

1.

Start engine and warm it up to normal operating temperature.

2.

Set “POST TRIGGER” to 100% in “DATA MONITOR” mode with CONSULT-III. 

3.

Select “HO2S1 (B1)” and “HO2S1 MNTR (B1)”.

4.

Hold engine speed at 2,000 rpm under no load during the following steps.

5.

Touch “RECORD” on CONSULT-III screen.

6.

Check the following.

-

“HO2S1 MNTR (B1)” in “DATA MONITOR” mode changes from
“RICH” to “LEAN” to “RICH” more than 5 times in 10 seconds.

5 times (cycles) are counted as shown in the figure.

-

“HO2S1 (B1)” voltage goes above 0.6 V at least once.

-

“HO2S1 (B1)” voltage goes below 0.3 V at least once.

-

“HO2S1 (B1)” voltage never exceeds 1.0 V.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> GO TO 4.

3.

CHECK HEATED OXYGEN SENSOR 1

 Without CONSULT-III

1.

Start engine and warm it up to normal operating temperature.

2.

Check the voltage between ECM harness connector and ground under the following condition.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> GO TO 4.

4.

REPLACE HEATED OXYGEN SENSOR 1

Replace heated oxygen sensor 1.

CAUTION:

• Discard any heated oxygen sensor which has been dropped from a height of more than 0.5 m (19.7

in) onto a hard surface such as a concrete floor; use a new one.
