PERFORM COMPONENT FUNCTION CHECK
With GST
1. Start engine and warm it up to normal operating temperature.
2. Drive the vehicle at a speed of 80 km/h (50 MPH) for a few minutes in the suitable gear position.
3. Shift the selector lever to D position (A/T or CVT) or 5th position (M/T), then release the accelerator pedal
fully until the vehicle speed decreases to 50 km/h (30 MPH).
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
Never apply brake when releasing the accelerator pedal.
4. Repeat steps 2 and 3 for five times.
5. Stop the vehicle and turn ignition switch OFF.
6. Turn ignition switch ON.
7. Turn ignition switch OFF and wait at least 10 seconds.
8. Restart engine.
9. Repeat steps 2 and 3 for five times.
10. Stop the vehicle and connect GST to the vehicle.
11. Check 1st trip DTC.
Is 1st trip DTC detected?
YES
>> Go to
NO

Diagnosis Procedure
INFOID:0000000009267111
1.
CHECK GROUND CONNECTION
1. Turn ignition switch OFF.
2. Check ground connection E15. Refer to Ground Inspection in
.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Repair or replace ground connection.
2.
CHECK AIR FUEL RATIO (A/F) SENSOR 1 POWER SUPPLY CIRCUIT
1. Disconnect A/F sensor 1 harness connector.
2. Turn ignition switch ON.
3. Check the voltage between A/F sensor 1 harness connector and ground.

• 20A fuse (No. 53)
• Harness for open or short between A/F sensor 1 and fuse
>> 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-45, "Intermittent Incident"
.
Is the inspection result normal?
YES
>> GO TO 6.
NO
>> Repair or replace.
6.

• Discard any A/F 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 A/F sensor, clean exhaust system threads using Oxygen Sensor Thread
Cleaner [commercial service tool (J-43897-18 or J-43897-12)] and approved anti-seize lubricant
(commercial service tool).

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
>> Go to
NO
>> GO TO 3.
3.
PERFORM DTC CONFIRMATION PROCEDURE
1. Turn ignition switch OFF and wait at least 10 seconds and then restart engine.
