6. Check the voltage when revving up to 4,000 rpm under no load
at least 10 times.
(Depress and release accelerator pedal as soon as possible.)
The voltage should be above 0. 68 V (M/T and A/T) or 0.72V
(CVT) at least once during this procedure.
If the voltage can be confirmed in step 6, step 7 is not nec-
essary.
7. Keep vehicle idling for 10 minutes, then check the voltage. Or check the voltage when coasting from 80 km/h (50 MPH) in D
position with OD OFF (A/T), D position (CVT) or 3rd gear posi-
tion (M/T).
The voltage should be above 0. 68 V (M/T and A/T) or 0.72V

Always drive vehicle at a safe speed.
10. Release the accelerator pedal fully at least 5 seconds. CAUTION:
• Enable engine brake.
• Always drive carefully.
• Never apply brake when releasing the accelerator pedal.
11. Repeat step 9 and 10 at least 8 times.
12. Check the following item of “DATA MONITOR”.
Is
“CMPLT” displayed on CONSULT-III screen?
YES >> GO TO 6.
NO-1: “CMPLT” is not displayed on DIAG 1>>Perform DTC confirmation procedure again.
NO-2: “CMPLT” is not disp layed on DIAG 2>>GO TO 4.
4.PERFORM DTC WORK SUPPORT
1. Open engine hood.
2. Select “HO2S2 (B1) P0139” in “DTC WORK SUPPORT” mode with CONSULT-III.
3. Start engine and follow the instruction of CONSULT-III display. NOTE:
It will take at most 10 minutes until “COMPLETED” is displayed.
Is
“COMPLETED” displayed on CONSULT-III screen?
YES >> GO TO 6.
NO >> GO TO 5.
5.PERFORM DTC CONFIRMATION PROCEDURE AGAIN
1. Turn ignition switch OFF and leave the vehi cle in a cool place (soak the vehicle).
2. Perform DTC confirmation procedure again.

7.PERFORM OVERALL FUNCTION CHECK
Perform component function check. Refer to EC-743, "
Overall Function Check".
NOTE:
Use overall function check to check the overall func tion of the heated oxygen sensor 2 circuit. During this
check, a 1st trip DTC might not be confirmed.

Overall Function CheckINFOID:0000000005532592
Use this procedure to check the overall function of the heated oxygen sensor 2 circuit. During this check, a 1st
trip DTC might not be confirmed.
WITH GST
1. Start engine and warm it up to the normal operating temperature.
2. Turn ignition switch OFF and wait at least 10 seconds.
3. Start engine and keep the engine between 3,500 and 4,000 rpm for at least 1 minute under no load.
4. Let engine idle for 1 minute.
5. Set voltmeter probes between ECM terminal 50 (HO2S2 signal) and ground.
6. Check the voltage when revving up to 4,000 rpm under no load at least 10 times.
(Depress and release accelerator pedal as soon as possible.)
A change of voltage should be more than 0.8 V for 1 second
during this procedure.
If the voltage can be confirmed in step 6, step 7 is not nec-
essary.
7. Keep vehicle at idling for 10 minutes, then check the voltage. Or check the voltage when coasting from 80 km/h (50 MPH) in D
position with OD OFF (A/T), D position (CVT) or 3rd gear posi-
tion (M/T).
A change of voltage should be more than 0.8 V for 1 second
