CHECK A/F SENSOR 1 INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connector.

3.

NO

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

4.

CHECK INTERMITTENT INCIDENT

Check intermittent incident. Refer to 

GI-33, "Intermittent Incident"

.

Is the inspection result normal?

YES

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

EM-32, "Exploded View"

.

NO

>> Repair or replace.

DTC Logic

INFOID:0000000005989258

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 turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
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-III.

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

>> Go to 

EC-150, "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

>> Go to 

EC-150, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000005989259

1.

CHECK AIR FUEL RATIO (A/F) SENSOR 1 POWER SUPPLY CIRCUIT

1.

Disconnect A/F sensor 1 harness connector.

DTC No.

3.

Check the voltage between A/F sensor 1 harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

DETECT MALFUNCTIONING PART

Check harness for open or short between A/F sensor 1 and fuse.

>> Repair or replace harness or connectors.

3.

CHECK A/F SENSOR 1 INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

1.
