Component DescriptionEBS00B46
The heated oxygen sensor 1 is placed into the front tube. It detects
the amount of oxygen in the exhaust gas compared to the outside
air. The heated oxygen sensor 1 has a closed-end tube made of
ceramic zirconia. The zirconia generates voltage from approximately
1V in richer conditions to 0V in leaner conditions. The heated oxygen
sensor 1 signal is sent to the ECM. The ECM adjusts the injection
pulse duration to achieve the ideal air-fuel ratio. The ideal air-fuel
ratio occurs near the radical change from 1V to 0V.
CONSULT-II Reference Value in Data Monitor ModeEBS00B47
Specification data are reference values.
ECM Terminals and Reference ValueEBS00B48
Specification data are reference values and are measured between each terminal and body 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.

On Board Diagnosis LogicEBS00B4J
Under the condition in which the heated oxygen sensor 1 signal is
not input, the ECM circuits will read a continuous approximately
0.3V. Therefore, for this diagnosis, the time that output voltage is
within 200 to 400 mV range is monitored, and the diagnosis checks
that this time is not inordinately long.
DTC Confirmation ProcedureEBS00B4K
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:
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) P0134" 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 3,600 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.

lIf “COMPLETED” already appears at “COND2” on CONSULT-II screen before “Procedure for
COND2” is conducted, it is unnecessary to conduct step 1 in “Procedure for COND2”.
Procedure for COND2
1. While driving, release accelerator pedal completely with “OD”
OFF (A/T models only) from the above condition [step 8] until
“INCOMPLETE” at “COND2” on CONSULT-II screen has turned
to “COMPLETED”. (It will take approximately 4 seconds.)
NOTE:
If “COMPLETED” already appears at “COND3” on CONSULT-II
screen before “Procedure for COND3” is conducted, it is unnec-
essary to conduct step 1 in “Procedure for COND3”.
Procedure for COND3
1. Stop vehicle and let it idle until “INCOMPLETE” of “COND3” on
CONSULT-II screen has turned to “COMPLETED”. (It will take a
maximum of approximately 6 minutes.)
2. Make sure that “OK” is displayed after touching “SELF-DIAG
RESULTS”.
If "NG" is displayed, refer toEC-191, "
Diagnostic Procedure".
Overall Function CheckEBS00B55
Use this procedure to check the overall function of the heated oxygen sensor 2 circuit. During this check, a 1st
trip DTC might not be confirmed.
WITH GST
1. Start engine and drive vehicle at a speed of more than 70 km/h (43 MPH) for 2 consecutive minutes.
2. Stop vehicle with engine running.
3. Set voltmeter probes between ECM terminal 95 [HO2S2 (B1) signal] and engine ground.
4. Check the voltage when revving up to 4,000 rpm under no load
at least 10 times.
(Depress and release accelerator pedal as soon as possible.)
The voltage should change at more than 0.06V for 1 second
during this procedure.
If the voltage can be confirmed in step 4, step 5 is not nec-
essary.
5. Keep vehicle at idling for 10 minutes, then check the voltage. Or
check the voltage when coasting from 80 km/h (50 MPH) in “D”
position with “OD” OFF (A/T), 3rd gear position (M/T).
The voltage should change at more than 0.06V for 1 second
during this procedure.

6. Rev engine up to 2,000 to 3,000 rpm and maintain it until
“INCMP” of "CATALYST" changes to “CMPLT” (It will take
approximately 5 minutes).
If not “CMPLT”, stop engine and cool it down to less than 70°C
(158°F) and then retest from step 1.
7. Select “SELF-DIAG RESULTS” mode with CONSULT-II.
8. Confirm that the 1st trip DTC is not detected.
If the 1st trip DTC is detected, go toEC-231, "
Diagnostic Proce-
dure".
Overall Function CheckEBS00B6C
Use this procedure to check the overall function of the three way catalyst (Manifold). During this check, a 1st
trip DTC might not be confirmed.
CAUTION:
Always drive vehicle at a safe speed.
WITH GST
1. Start engine and drive vehicle at a speed of more than 70 km/h (43 MPH) for 2 consecutive minutes.
2. Stop vehicle with engine running.
3. Set voltmeters probes between ECM terminal 92 [HO2S1 signal]
and engine ground, and ECM terminal 95 [HO2S2 signal] and
engine ground.
4. Keep engine speed at 2,000 rpm constant under no load.
5. Make sure that the voltage switching frequency (high & low)
between ECM terminal 95 and engine ground is very less than
that of ECM terminal 92 and engine ground.
Switching frequency ratio = A/B
A: Heated oxygen sensor 2 voltage switching frequency
B: Heated oxygen sensor 1 voltage switching frequency
This ratio should be less than 0.75.
If the ratio is greater than above, it means three way catalyst
does not operate properly. Go toEC-231, "
Diagnostic Proce-
dure".
NOTE:
If the voltage at terminal 92 does not switch periodically more than 5
times within 10 seconds at step 5, perform trouble diagnosis for “DTC P0133” first. (SeeEC-166
.)
