Description
INFOID:0000000001697491
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.
Component Function Check
INFOID:0000000001697492
1.
CHECK HEATED OXYGEN SENSOR 1 FUNCTION
With CONSULT-III
1.
Start engine and warm it up to normal operating temperature.
2.
Select “HO2S1 MNITOR (B1)” in ”DATA MONITOR” mode with CONSULT-III.
3.
Keep the engine speed at 2,000 rpm under no load, and make
sure that the monitors fluctuates between LEAN and RICH more
than five times in 10 seconds.
Without CONSULT-III
1.
Start engine and warm it up to normal operating temperature.
2.
Stop engine and wait at least 10 seconds.
3.
Set ECM in Diagnostic test mode - II (Heated oxygen sensor 1 monitor).

Diagnosis Procedure
INFOID:0000000001697493
1.
CHECK GROUND CONNECTION
1.
Turn ignition switch OFF.
2.
Check ground connection E21. Refer to Ground Inspection in
.
Is the inspection result normal?
YES
>> GO TO 2
NO
>> Repair or replace ground connection.
2.
RETIGHTEN HEATED OXYGEN SENSOR 1
Loosen and retighten the heated oxygen sensor 1.
>> GO TO 3.
3.
CHECK EXHAUST GAS LEAK
1.
