DTC Confirmation Procedure
UBS00DI6
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 5 seconds before conducting the next test.
TESTING CONDITION:
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.
Select “HO2S1 (B1)/(B2) P0134/P0154” of “HO2S1” in “DTC
WORK SUPPORT” mode with CONSULT-II.
3.
Touch “START”.
4.
Let it idle for at least 3 minutes.
NOTE:
Never raise engine speed above 2,800 rpm after this step. If
the engine speed limit is exceeded, return to step 4.
5.
When the following conditions are met, “TESTING” will be dis-
played on the CONSULT-II screen. Maintain the conditions con-
tinuously until “TESTING” changes to “COMPLETED”. (It will
take approximately 10 to 60 seconds.)
If “TESTING” is not displayed after 5 minutes, retry from
step 2.
6.
Make sure that “OK” is displayed after touching “SELF-DIAG
RESULTS”. If “NG” is displayed, refer to
During this test, P1148 and P1168 may be stored in ECM.
Overall Function Check
UBS00DI7
Use this procedure to check the overall function of the heated oxygen sensor 1 circuit. During this check, a
DTC might not be confirmed.
WITH GST
1.
Start engine and warm it up to normal operating temperature.
2.
Set voltmeter probes between ECM terminal 50 [HO2S1 (B1) signal] or 51 [HO2S1 (B2) signal] and
engine ground.

Check the following with engine speed held at 2,000 rpm con-
stant under no load.
–
The voltage does not remain in the range of 0.2 to 0.4V.

Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than the ECM terminals, such as the ground.
