CHECK A/F SENSOR 1 INPUT SIGNAL 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 ground and short to power.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace malfunctioning part.

4.

REPLACE A/F SENSOR 1

Replace malfunctioning A/F sensor 1. Refer to 

EM-153, "Exploded View"

.

CAUTION:

• Discard any A/F 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.

• Before installing new A/F sensor, clean exhaust system threads.

DTC Description

INFOID:0000000010702927

DTC DETECTION LOGIC

The heated oxygen sensor 2 has a much longer switching time
between rich and lean than the air fuel ratio (A/F) sensor 1. The oxy-
gen storage capacity of the three way catalyst (manifold) causes the
longer switching time.

: 0.77V

To judge the malfunctions of heated oxygen sensor 2, ECM monitors
whether the maximum voltage of the sensor is sufficiently high dur-
ing various driving conditions such as fuel cut.

POSSIBLE CAUSE

• Harness or connectors (The heated oxygen sensor 2 circuit is open or shorted.)
• Heated oxygen sensor 2
• Fuel pressure
• Fuel injector
• Intake air leaks

FAIL-SAFE

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
TESTING CONDITION:
Check that “COOLAN TEMP/S” indicates between 0

°

C to 30

°

C (30

°

F to 86

°

F) before conducting follow-

ing procedure.
Will CONSULT be used?

YES

>> GO TO 2.

NO

>> GO TO 4.

2.

PERFORM DTC CONFIRMATION PROCEDURE

WITH CONSULT

1.

Turn ignition switch ON and select “DATA MONITOR” mode with CONSULT.

2.

Start engine and warm it up to the normal operating temperature.

3.

Turn ignition switch OFF and wait at least 10 seconds.

4.

Restart engine and keep the engine speed between 3,500 and 4,000 rpm for at least 1 minute under no
load.

5.

Let engine idle for 1 minute.

6.

Check that “COOLAN TEMP/S” indicates more than 70

°

C (158

°

F).

If not, warm up engine and go to next step when “COOLAN TEMP/S” indication reaches 70

°

C (158

°

F).

7.

Open engine hood.

8.

Select “O

2

 (B1) P0137” of “HO2S2” in “DTC WORK SUPPORT” mode with CONSULT.

9.

Follow the instruction of CONSULT display.

CAN NOT BE DIAGNOSED>>GO TO 3.

3.

PERFORM DTC CONFIRMATION PROCEDURE AGAIN

1.

Turn ignition switch OFF and leave the vehicle in a cool place (soak the vehicle).

2.

Perform DTC confirmation procedure again.

>> GO TO 2.

4.

PERFORM COMPONENT FUNCTION CHECK-1

WITHOUT CONSULT

NOTE:
Use component function check to check the overall function of the heated oxygen sensor 2 circuit. During this
check, a 1st trip DTC might not be confirmed.
1.

Start engine and warm it up to the normal operating temperature.

2.

Turn ignition switch OFF and wait at least 10 seconds.

3.

Restart 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 terminals under the following conditions.

Is the inspection result normal?

YES-1 >> To check malfunction symptom before repair: Refer to 

GI-41, "Intermittent Incident"

.

YES-2 >> Confirmation after repair: INSPECTION END
NO

>> GO TO 5.

5.

PERFORM COMPONENT FUNCTION CHECK-2

Check the voltage between ECM harness connector terminals under the following conditions.

Is the inspection result normal?

YES-1 >> To check malfunction symptom before repair: Refer to 

GI-41, "Intermittent Incident"

.

YES-2 >> Confirmation after repair: INSPECTION END
