DTC Detecting Condition and Possible Cause
DTC Confirmation Procedure
WARNING
!
• When performing a road test, select a
place where there is no traffic or
possibility of a traffic accident and very
careful during testing to avoid occurrence
of an accident.
• Road test should be carried out with 2
persons, a driver and tester, on a level
road.
NOTE
Check to make sure that the following
conditions are satisfied when using this DTC
confirmation procedure.
• Altitude (barometric pressure): 2400 m,
8000 ft or less (560 mmHg, 75 kPa or more)
• Ambient temp.: –10
°
C, 14
°
F or higher
• Intake air temp.: 70
°
C, 158
°
F or lower
• No exhaust gas leakage and loose
connection
1) Turn ignition switch OFF.
Clear DTC with ignition switch ON.
2) Warm up engine to normal operating temperature.
3) Drive vehicle under usual driving condition for 5 min.
and check HO2S-2 output voltage and “short term
fuel trim” with “Data List” mode on scan tool, and
write it down.
4) Stop vehicle (don’t turn ignition switch OFF).
5) Increase vehicle speed to higher than 20 mph, 32
km/h and then stop vehicle.
6) Repeat above steps 5) 4 times.
7) Increase vehicle speed to about 80 km/h (50 mph) in
3rd gear or 2 range.
8) Release accelerator pedal and with engine brake
applied, keep vehicle coasting (fuel cut condition) for
10 sec. or more.
9) Stop vehicle (do not turn ignition switch OFF) and
run engine at idle for 2 min.
After this Step 9), if “Oxygen Sensor Monitoring
TEST COMPLETED” is displayed in “READINESS
TESTS” mode and DTC is not displayed in “DTC”
mode, confirmation test is completed.
If “TEST NOT COMPLTD” is still being displayed,
proceed to next Step 10).
10) Drive vehicle under usual driving condition for 10
min. (or vehicle is at a stop and run engine at idle for
10 min. or longer)

DTC detecting condition
Possible cause
DTC will set when one of the following conditions is detected.
• HO2S-2 output voltage is higher than specified value while vehicle
driving.
• Engine is warmed up and HO2S-2 voltage is 4.5 V or more.
(circuit open)
*2 driving cycle detection logic, monitoring once / 1 driving
• Exhaust gas leakage
• “WHT” or “ORN” circuit open or short
• Heated oxygen sensor-2 malfunction
• Fuel system malfunction
