Diagnostic Procedure

SEF484YE
On Board Diagnosis LogicNEEC1050The ECM monitors the switching frequency ratio of heated oxygen
sensor 1 and 2.
A three way catalyst with high oxygen storage capacity will indicate
a low switching frequency of heated oxygen sensor 2. As oxygen
storage capacity decreases, the heated oxygen sensor 2 switching
frequency will increase.
When the frequency ratio of heated oxygen sensors 1 and 2
approaches a specified limit value, the three way catalyst malfunc-
tion is diagnosed.
DTC No. Malfunction is detected when ... Check Items (Possible Cause)

DTC Confirmation ProcedureNEEC1051NOTE:
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:
+Open engine hood before conducting following proce-
dure.
+Do not hold engine speed more than specified minutes
below.
With CONSULT-II
1) Turn ignition switch ªONº.
2) Select ªDTC & SRT CONFIRMATIONº then ªSRT WORK SUP-
PORTº mode with CONSULT-II.
3) Start engine.
4) Rev engine up to 2,500 to 3,500 rpm and hold it for 3 consecu-
tive minutes then release then accelerator pedal completely.
If ªINCMPº of ªCATALYSTº changes to ªCMPLTº, go to step 7.
5) Wait 5 seconds at idle.
6) Rev engine up to 2,500 to 3,500 rpm and hold it until ªINCMPº
of ªCATALYSTº changes to ªCMPLTº. (It will take maximum of
approximately 5 minute.)

7) Select ªSELF-DIAG RESULTSº mode with CONSULT-II.
If the 1st trip DTC is detected, go to ªDIAGNOSTIC
PROCEDUREº, EC-3280. If not ªCOMPLTº stop engine and
cool down ªCOOLANT TEMP/SEº to less than 70ÉC (158ÉF)
and then retest from step 1).
