>> GO TO 3.

5.

PERFORM COMPONENT FUNCTION CHECK

Perform component function check. Refer to 

EC-196, "Component Function Check"

.

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.
Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Go to 

EC-197, "Diagnosis Procedure"

.

EC-18, "MIXTURE RATIO SELF-LEARNING VALUE

CLEAR : Special Repair Requirement"

.

2. Activate “INSPECTION MODE 1” (

HBC-104

) to start engine, and let engine idle for at least 10 minutes.

Is the 1st trip DTC P0171 detected? Is it difficult to start engine?

YES

>> Perform trouble diagnosis for DTC P0171. Refer to 

EC-224, "DTC Logic"

.

NO

>> GO TO 3.

3.

CHECK HO2S2 GROUND CIRCUIT FOR OPEN AND SHORT

1. Turn ignition switch OFF.

2. Disconnect heated oxygen sensor 2 harness connector.

3. Disconnect ECM harness connector.

4. Check the continuity between HO2S2 harness connector and ECM harness connector.

5. 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 HO2S2 INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

1. Check the continuity between HO2S2 harness connector and ECM harness connector.

2. Check the continuity between HO2S2 harness connector or ECM harness connector and ground.
