Description

INFOID:0000000001693259

The heated oxygen sensor 1 is placed into the exhaust manifold. 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.

DTC Logic

INFOID:0000000001693260

DTC DETECTION LOGIC

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 PROCEDURE

1.

PRECONDITIONING

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.

Do you have CONSULT-III?

PERFORM DTC CONFIRMATION PROCEDURE-I

With CONSULT-III

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) P0134” of “HO2S1” in “DTC WORK SUPPORT” mode
with CONSULT-III.

4.

Touch “START”.

5.

Start engine and 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 5.

6.

When the following conditions are met, “TESTING” will be displayed on the CONSULT-III screen. Maintain
the conditions continuously until “TESTING” changes to “COMPLETED”. (It will take approximately 40 to
50 seconds.)

CAUTION:

Always drive vehicle at a safe speed.

If “TESTING” is not displayed after 5 minutes, retry from step 2.

7.

Touch “SELF-DIAG RESULTS”.

Which displayed on COUSULT-III screen?

OK

>> INSPECTION END.
