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.
Without CONSULT-II
1.
Reconnect all harness connectors disconnected.
2.
Start engine and warm it up to normal operating temperature.
3.
Set voltmeter probes between ECM terminal 50 [Heated oxygen
sensor 1 signal] and engine ground.
4.
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.
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
–
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.

Component Description
UBS00D41
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
UBS00D42
Specification data are reference values.
On Board Diagnosis Logic
UBS00D43
To judge the malfunction of heated oxygen sensor 1, this diagnosis
measures response time of heated oxygen sensor 1 signal. The time
is compensated by engine operating (speed and load), fuel feedback
control constant, and heated oxygen sensor 1 temperature index.
Judgment is based on whether the compensated time [heated oxy-
gen sensor 1 cycling time index] is inordinately long or not.

DTC Confirmation Procedure
UBS00D44
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:
●
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 5 seconds.
3.
Turn ignition switch ON and select “HO2S1 (B1) P0133” 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 3,600 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 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.

Make sure that “OK” is displayed after touching “SELF-DIAG
RESULTS”. If “NG” is displayed, refer to
Overall Function Check
UBS00D45
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
1.
Start engine and warm it up to normal operating temperature.
2.
Set voltmeter probes between ECM terminal 50 (Heated oxygen
sensor 1 signal) and engine 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.
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
