>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Start engine and warm it up to normal operating temperature.

2.

Maintain the following conditions for at least 11 consecutive minutes.

CAUTION:

Always drive vehicle at safe speed.

3.

Check DTC.

Is DTC is detected?

YES

>> Go to 

ECH-175, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000010379068

1.

CHECK ECM HARNESS CONNECTOR CONNECTIONS

Check ECM connector connection F18.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace ECM connector connection.

2.

CHECK HEATED OXYGEN SENSOR 1 HARNESS CONNECTOR CONNECTION

Check heated oxygen sensor 1 harness connector connection F48.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace heated oxygen sensor 1 harness connector.

3.

CHECK GROUND CONNECTION

Check ground connection E4. Refer to Ground Inspection in 

GI-43, "Circuit Inspection"

.

Is the inspection result normal?

YES

>> GO TO 4.

DTC No.

P0130 HO2S1

NO

>> Repair or replace ground connection.

4.

CHECK HO2S1 GROUND CIRCUIT FOR OPEN AND SHORT

1.

Disconnect heated oxygen sensor 1 harness connector.

2.

Disconnect ECM harness connector.

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 5.

NO

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

5.

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 6.

NO

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

6.

CHECK INTERMITTENT INCIDENT

Refer to 

GI-41, "Intermittent Incident"

.

Is the inspection result normal?

YES

>> Replace heated oxygen sensor 1.
