DTC Confirmation Procedure
ABS002GX
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 10 seconds before conducting the next test.
TESTING CONDITION:
●
Always perform at a temperature above
−
10
°
C (14
°
F).
●
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 10 seconds.
3.
Turn ignition switch ON and select “HO2S1 (B1) P0133” or “HO2S1 (B2) P0153” of “HO2S1” in “DTC
WORK SUPPORT” mode with CONSULT-II.
4.
Touch “START”.
5.
Start engine and let it idle for at least 3 minutes.
NOTE:
Never raise engine speed above 3,000 rpm after this step. If
the engine speed limit is exceeded, return to step 5.
6.
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 40 to 50 seconds.)
If “TESTING” is not displayed after 5 minutes, retry from
step 2.
DTC No.

Overall Function Check
ABS002GY
Use this procedure to check the overall function of the heated oxygen sensor 1 circuit. During this check, a 1st
trip 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 114 [HO2S1(B1) signal] or 115 [HO2S1(B2) signal] and
ground.
3.
Check the following with engine speed held at 2,000 rpm con-
stant under no load.
–
The voltage fluctuates between 0 to 0.3V and 0.6 to 1.0V more
than 5 times within 10 seconds.
4.
If NG, go to

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 ECM terminals, such as the ground.
