DTC Confirmation Procedure

CAUTION: Always drive vehicle at a safe speed.

NOTE: If "DTC Confirmation Procedure" has been previously conducted, a always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test.

With CONSULT
(1) Start engine and warm it up to normal operating temperature.
(2) Set "MANU TRIG" and "HI SPEED", then select "FR O2 SEN-B1 (-B2)", "RR O2 SEN-B1 (-B2)", "FR O2 MNTR-B1 (-B2)", "RR O2 MNTR-B1 (-B2)" in "DATA MONITOR" mode with CONSULT.





(3) Touch "RECORD" on CONSULT screen with engine speed held at 2,000 rpm constantly under no load.
(4) Make sure that the switching frequency between "RICH" and "LEAN" of "RR O2 MNTR-B1 (-B2)" is much less than that of "FR O2 MNTR-B1 (-B2)" as shown below.
Switching frequency ratio = A/B
A: Rear heated oxygen sensor switching frequency
B: Front heated oxygen sensor switching frequency This ratio should be less than 0.75.
If the ratio is greater than above, the warm-up three way catalyst is not operating properly.
If the "FR O2 MNTR-B1 (-B2)" does not indicate "RICH" and "LEAN" periodically more than 5 times within 10 seconds at step 3, perform trouble diagnosis for "DTC P0133, P0153" first.
If the result is NG, go to "Diagnostic Procedure".
If the result is OK, go to following step.
(5) Select "AUTO TRIG" in "DATA MONITOR" mode with CONSULT.
(6) Drive vehicle at a speed of approximately 86 to 96 km/h (53 to 60 MPH) with D position ("OD" ON) for at least 10 consecutive minutes.
(Drive the vehicle in an area where vehicle speed and accelerator pressure can be held steady and constant.)
If the result is NG, go to "Diagnostic Procedure".
(7) Select "SRT STATUS" in "DTC CONFIRMATION" mode with CONSULT.





(8) Verity that "CATALYST" is "CMPLT".
If not "CMPLT", repeat the test from step 5.
