Is the inspection result normal?
YES
>> GO TO 5.
NO
>> Repair or replace error-detected parts.
5.
REPLACE A/F SENSOR
Replace A/F sensor.
CAUTION:
• 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 Heated Oxygen Sensor
Thread Cleaner tool and approved anti-seize lubricant.
