On Board Diagnosis LogicNLEC0122To judge the malfunction of heated oxygen sensor 1 (front), this
diagnosis measures response time of heated oxygen sensor 1
(front) signal. The time is compensated by engine operating (speed
and load), fuel feedback control constant, and heated oxygen sen-
sor 1 (front) temperature index. Judgment is based on whether the
compensated time [heated oxygen sensor 1 (front) cycling time
index] is inordinately long or not.

DTC Confirmation ProcedureNLEC0123CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If ªDTC Confirmation Procedureº has been previously conducted,
always turn ignition switch ªOFFº and wait at least 9 seconds
before conducting the next test.
TESTING CONDITION:
+Always perform at a temperature above þ10ÉC (14ÉF).
+Before performing the following procedure, confirm that
battery voltage is more than 11V at idle.
With CONSULT-II
1) Start engine and warm it up to normal operating temperature.
2) Stop engine and wait at least 9 seconds.
3) Turn ignition switch ªONº and select ªHO2S1 (B1) P0133º of
ªHO2S1º in ªDTC WORK SUPPORTº mode with CONSULT-II.
4) Touch ªSTARTº.
5) Start engine and let it idle for at least 3 minutes.
NOTE:
Never raise engine speed above 3,200 rpm after this step. If
the engine speed limit is exceeded, return to step 5.
6) When the following conditions are met, ªTESTINGº will be dis-
played on the CONSULT-II screen. Maintain the conditions
continuously until ªTESTINGº changes to ªCOMPLETEDº. (It
will take approximately 50 seconds.)
ENG SPEED 2,100 - 3,100 rpm
Vehicle speed 80 - 120 km/h (50 - 75 MPH)
B/FUEL SCHDL 3.8 - 7.6 msec
Selector lever Suitable position
If ªTESTINGº is not displayed after 5 minutes, retry from
step 2.

Overall Function CheckNLEC0595Use this procedure to check the overall function of the rear heated
oxygen sensor circuit. During this check, a 1st trip DTC might not
be confirmed.
Without CONSULT-II
