CHECK HEATED OXYGEN SENSOR 1

With CONSULT-II

Start engine and warm it up to normal operating temperature.

Select “MANU TRIG” in “DATA MONITOR” mode with CONSULT-II, and select “HO2S1 (B1)/(B2)” and
“HO2S1 MNTR (B1)/(B2)”.

Hold engine speed at 2,000 rpm under no load during the following steps.

Touch “RECORD” on CONSULT-II screen.

Check the following.

–

“HO2S1 MNTR (B1)/(B2)” in “DATA MONITOR” mode changes
from “RICH” to “LEAN” to “RICH” more than 5 times in 10 sec-
onds.
5 times (cycles) are counted as shown below.

–

“HO2S1 (B1)/(B2)” voltage goes above 0.6V at least once.

–

“HO2S1 (B1)/(B2)” voltage goes below 0.3V at least once.

–

“HO2S1 (B1)/(B2)” voltage never exceeds 1.0V.

CAUTION:

●

Discard any heated oxygen sensor which has been dropped from a height of more than 0.5 m (19.7
in) onto a hard surface such as a concrete floor; use a new one.

●

Before installing new oxygen sensor, clean exhaust system threads using Oxygen Sensor Thread
Cleaner tool J-43897-18 or J-43897-12 and approved anti-seize lubricant.

OK or NG

>> GO TO 11.

>> Replace malfunctioning heated oxygen sensor 1.

CHECK FRONT HEATED OXYGEN SENSOR 1

Without CONSULT-II

Start engine and warm it up to normal operating temperature.

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 fluctuates between 0 to 0.3V and 0.6 to 1.0V more
than 5 times within 10 seconds.

●

The maximum voltage is over 0.6V at least 1 time.

●

The minimum voltage is below 0.3V at least 1 time.

●

The voltage never exceeds 1.0V.

1 time: 0 - 0.3V

→ 0.6 - 1.0V → 0 - 0.3V

2 times: 0 - 0.3V

→ 0.6 - 1.0V → 0 - 0.3V → 0.6 - 1.0V → 0 - 0.3V

CAUTION:

●

Discard any heated oxygen sensor which has been dropped
from a height of more than 0.5 m (19.7 in) onto a hard surface such as a concrete floor; use a new
one.

●

Before installing new oxygen sensor, clean exhaust system threads using Oxygen Sensor Thread
Cleaner tool J-43897-18 or J-43897-12 and approved anti-seize lubricant.

PFP:22690

Component Description

UBS00DVC

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

UBS00DVD

Specification data are reference values.

On Board Diagnosis Logic

UBS00DVE

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

UBS00DVF

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

Start engine and warm it up to normal operating temperature.

Select “HO2S1 (B1)/(B2) P0134/P0154” of “HO2S1” in “DTC
WORK SUPPORT” mode with CONSULT-II.

Touch “START”.

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.

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.

Make sure that “OK” is displayed after touching “SELF-DIAG
RESULTS”. If “NG” is displayed, refer to

EC-1404, "Diagnostic

Procedure"

During this test, P1148 and P1168 may be stored in ECM.

Overall Function Check

UBS00DVG

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

Start engine and warm it up to normal operating temperature.

Set voltmeter probes between ECM terminal 50 [HO2S1 (B1) signal] or 51 [HO2S1 (B2) signal] and
engine ground.
