>> Repair or replace harness or connectors.

4.

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 power.
Is the inspection result normal?

YES

>> GO TO 5.

NO

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

5.

CHECK INTERMITTENT INCIDENT

Perform 

GI-41, "Intermittent Incident"

.

Is the inspection result normal?

YES

>> Replace malfunctioning air fuel ratio (A/F) sensor 1. Refer to 

EM-31, "Exploded View"

.

NO

>> Repair or replace.

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 low.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure

before conducting the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

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

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

2. Select “ENGINE” using CONSULT.

3. Select “A/F SEN1 (B1)” in “DATA MONITOR” mode.

4. Check “A/F SEN1 (B1)” indication.
Is the indication constantly approx. 0 V?

YES

>> Proceed to 

EC-174, "Diagnosis Procedure"

.

NO

>> GO TO 3.

3.

PERFORM DTC CONFIRMATION PROCEDURE

1. Turn ignition switch OFF and wait at least 10 seconds and then restart engine.

2. Drive and accelerate vehicle to more than 40 km/h (25 MPH) within 20 seconds after restarting engine.

CAUTION:

Always drive vehicle at a safe speed.

3. Maintain the following conditions for about 20 consecutive seconds.

NOTE:

• Keep the accelerator pedal as steady as possible during cruising.

• If this procedure is not completed within 1 minute after restarting engine at step 1, return to step

1.

4. Check 1st trip DTC.
Is 1st trip DTC detected?

YES

>> Proceed to 

EC-174, "Diagnosis Procedure"

.

NO

>> INSPECTION END

DTC No.
