DTC Confirmation Procedure

EBS00QK1

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

−

C (14

F).

●

Before performing the following procedure, confirm that battery voltage is more than 11V at idle.

WITH CONSULT-II

Start engine and warm it up to normal operating temperature.

Stop engine and wait at least 10 seconds.

Turn ignition switch “ON” and select “HO2S1 (B1) P0133” or “HO2S1 (B2) P0153” of “HO2S1” in “DTC
WORK SUPPORT” mode with CONSULT-II.

Touch “START”.

Start engine and let it idle for at least 3 minutes.

NOTE:
Never raise engine speed above 3,200 rpm after this step. If
the engine speed limit is exceeded, return to step 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 20 to 50 seconds.)

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

DTC P0134 HO2S1 (M/T MODELS)

PFP:22690

Component Description

EBS00QK7

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.

CONSULT-II Reference Value in Data Monitor Mode

EBS00QK8

Specification data are reference values.

On Board Diagnosis Logic

EBS00QK9

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.
