5.
Touch “RECORD” on CONSULT-III screen.
6.
Check the following.
-
“HO2S1 MNTR (B1)” in “DATA MONITOR” mode changes from
“RICH” to “LEAN” to “RICH” more than 5 times in 10 seconds.
5 times (cycles) are counted as shown in the figure.
-
“HO2S1 (B1)” voltage goes above 0.6V at least once.
-
“HO2S1 (B1)” voltage goes below 0.3V at least once.
-
“HO2S1 (B1)” 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 and approved anti-seize lubricant.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> GO TO 3.
3.
CHECK HEATED OXYGEN SENSOR 1
Without CONSULT-III
1.
Start engine and warm it up to normal operating temperature.
2.
Check the voltage between ECM harness connector and ground under the following condition.
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.

Description
INFOID:0000000001089348
SYSTEM DESCRIPTION
The ECM performs ON/OFF duty control of the heated oxygen sensor 1 heater corresponding to the engine
speed and engine coolant temperature. The duty percent varies with engine coolant temperature when engine
is started.
DTC Logic

DTC DETECTION LOGIC
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 between 11V at
idle.
>> GO TO 2.
2.
PERFORM DTC CONFIRMATION PROCEDURE
1.
Turn ignition switch ON.
2.
Select “DATA MONITOR” mode with CONSULT-III.
3.
Wait at least 5 seconds.
4.
Check 1st trip DTC.
Is 1st trip DTC detected?
YES
>> Go to
NO
>> INSPECTION END
Diagnosis Procedure
INFOID:0000000001089350
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.
CHECK HO2S1 POWER SUPPLY CIRCUIT
1.
Disconnect heated oxygen sensor 1 harness connector.
