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

Is the inspection result normal?

YES

>> GO TO 3.

>> GO TO 2.

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

1. Turn ignition switch OFF.

2. Disconnect IPDM E/R harness connector.

3. Check the continuity between A/F sensor 1 harness connector and IPDM E/R harness connector.

4. Also check harness for short to ground.
Is the inspection result normal?

YES

>> Perform the trouble diagnosis for power supply circuit.

>> Repair or replace error-detected parts.

CHECK A/F SENSOR 1 INPUT SIGNAL CIRCUIT

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.

CHECK INTERMITTENT INCIDENT

Perform

GI-45, "Intermittent Incident"

Is the inspection result normal?

YES

>> GO TO 5.

>> Repair or replace error-detected parts.

REPLACE AIR FUEL RATIO (A/F) SENSOR 1

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

EM-44, "Exploded View"

CAUTION:

• Discard any 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 sensor, clean exhaust system threads using Oxygen Sensor Thread Cleaner

[commercial service tool (J-43897-18 or J43897-12)] and approved Anti-seize Lubricant (commercial

service tool).

DTC Logic

INFOID:0000000012197828

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

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.

CHECK A/F SENSOR FUNCTION

With CONSULT

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

2. Select “A/F SEN1 (B1)” in “DATA MONITOR” mode of “ENGINE” using CONSULT.

3. Check “A/F SEN1 (B1)” indication.

With GST

Follow the procedure “With CONSULT” above.
Is the indication constantly approx. 0 V?

YES

>> Proceed to

EC-268, "Diagnosis Procedure"

>> GO TO 3.

PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT

1. Turn ignition switch OFF, 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 the cruising.

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

4. Check 1st trip DTC.

With GST

DTC No.
