CAUTION:
Always drive vehicle at a safe speed.
NOTE:
+ªCOMPLETEDº will appear on CONSULT-II screen when all
tests ªCOND1º, ªCOND2º and ªCOND3º are completed.
+If ªDTC Confirmation Procedureº has been previously
conducted, always turn ignition switch ªOFFº and wait at least
5 seconds before conducting the next test.
TESTING CONDITION:
Never stop engine during this procedure. If the engine is
stopped, retry this procedure from step 2 in ªProcedure for
COND1º.
WITH CONSULT-IINEEC0166S01Procedure for COND1NEEC0166S01011. Start engine and warm it up to normal operating temperature.
2. Turn ignition switch ªOFFº and wait at least 5 seconds.
3. Turn ignition switch ªONº and select ªHO2S2 (B1) P0139º of
ªHO2S2º in ªDTC WORK SUPPORTº mode with CONSULT-II.
4. Touch ªSTARTº.
5. Start engine and let it idle for at least 30 seconds.
6. Rev engine up to 2,000 rpm 2 or 3 times quickly under no load.
If ªCOMPLETEDº appears on CONSULT-II screen, go to step
2 in ªProcedure for COND3º.
If ªCOMPLETEDº does not appear on CONSULT-II screen, go
to the following step.
7. Drive vehicle at a speed of more than 70 km/h (43 MPH) for 2
consecutive minutes.
8. When the following conditions are met, ªTESTINGº will be dis-
played at ªCOND1º on the CONSULT-II screen. Maintain the
conditions continuously until ªTESTINGº changes to ªCOM-
PLETEDº. (It will take approximately 60 seconds.)
ENG SPEED More than 1,000 rpm
B/FUEL SCHDL More than 1.0 msec
COOLANT TEMP/S 70 - 105ÉC
Selector level Suitable position
NOTE:
+If ªTESTINGº is not displayed after 5 minutes, retry from
step 2 in ªProcedure for COND1º.
+If ªCOMPLETEDº already appears at ªCOND2º on CON-
SULT-II screen before ªProcedure for COND2º is
conducted, it is unnecessary to conduct step 1 in ªProce-
dure for COND2º.

Procedure for COND2NEEC0166S01021. While driving, release accelerator pedal completely from the
above condition [step 8] until ªINCOMPLETEº at ªCOND2º on
CONSULT-II screen has turned to ªCOMPLETEDº. (If will take
approximately 4 seconds.)
NOTE:
If ªCOMPLETEDº already appears at ªCOND3º on CONSULT-II
screen before ªProcedure for COND3º is conducted, it is
unnecessary to conduct step 1 in ªProcedure for COND3º.
SEF668Y
Procedure for COND3NEEC0166S01031. Stop vehicle and let is idle until ªINCOMPLETEº of ªCOND3º
on CONSULT-II screen has turned to ªCOMPLETEDº. (It will
take a maximum of approximately 6 minutes.)
2. Make sure that ªOKº is displayed after touching ªSELF-DIAG
RESULTSº.
If ªNGº is displayed, refer to EC-3231, ªDiagnostic Procedureº.

Overall Function CheckNEEC0167Use this procedure to check the overall function of the heated oxy-
gen sensor 2 circuit. During this check, a 1st trip DTC might not be
confirmed.
CAUTION:
Always drive vehicle at a safe speed.
Without CONSULT-II
1) Start engine and drive vehicle at a speed of more than 70 km/h
(43 MPH) for 2 consecutive minutes.
2) Stop vehicle with engine running.
3) Set voltmeter probes between ECM terminals 56 (Heated oxy-
gen sensor 2 signal) and engine ground.
4) 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 change at more than 0.06V for 1 sec-
ond during this procedure.
If the voltage can be confirmed in step 4, step 5 is not
necessary.
5) Keep vehicle at idling for 10 minutes, then check the voltage.
Or check the voltage when coasting from 80 km/h (50 MPH)
in 3rd gear position.
The voltage should change at more than 0.06V for 1 sec-
ond during this procedure.
6) If NG, go to ªDiagnostic Procedureº, EC-3231.

Diagnostic Procedure
EC-3257

SEF463R
SEF288D
Component DescriptionNEEC0103The heated oxygen sensor 1 is placed into the exhaust manifold.
It detects the amount of oxygen in the exhaust gas compared to the
outside air. The heated oxygen sensor 1 has a closed-end tube
made of ceramic zirconia. The zirconia generates voltage from
approximately 1V in richer conditions to 0V in leaner conditions.
The heated oxygen sensor 1 signal is sent to the ECM. The ECM
adjusts the injection pulse duration to achieve the ideal air-fuel
ratio. The ideal air-fuel ratio occurs near the radical change from
1V to 0V.
