CHECK HEATED OXYGEN SENSOR 1

With CONSULT-II

1.

Start engine and warm it up to normal operating temperature. 

2.

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

3.

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

4.

Touch “RECORD” on CONSULT-II screen.

5.

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 left:

–

“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

OK

>> GO TO 14.

NG

>> Replace malfunctioning heated oxygen sensor 1.

CHECK HEATED OXYGEN SENSOR 1 (BANK1)(BANK2)

 Without CONSULT-II

1.

Start engine and warm it up to normal operating temperature.

2.

Set voltmeter probes between ECM terminal 50 (bank 1 sensor
signal) or 51 (bank 2 sensor 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.

●

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.

OK or NG

OK

>> GO TO 14.

NG

>> Replace malfunctioning heated oxygen sensor 1.

14. 

CHECK MASS AIR FLOW SENSOR

 With CONSULT-II

Check mass air flow sensor signal in “DATA MONITOR” mode with CONSULT-II.

 With GST

Check mass air flow sensor signal in MODE 1 with GST.

OK or NG

OK

>> GO TO 15.

NG

>> Check connectors for rusted terminals or loose connections in the mass air flow sensor circuit or

engine grounds. Refer to 

EC-720

 .

15. 

CHECK SYMPTOM MATRIX CHART

Check items on the rough idle symptom in 

EC-659, "Symptom Matrix Chart"

 .

OK or NG

OK

>> GO TO 16.

NG

>> Repair or replace. 

16. 

ERASE THE 1ST TRIP DTC

Some tests may cause a 1st trip DTC to be set.
Erase the 1st trip DTC from the ECM memory after performing the tests. Refer to 

EC-632, "HOW TO ERASE

EMISSION-RELATED DIAGNOSTIC INFORMATION"

 .

Component Description

UBS00DJH

The knock sensor is attached to the cylinder block. It senses engine
knocking using a piezoelectric element. A knocking vibration from
the cylinder block is sensed as vibrational pressure. This pressure is
converted into a voltage signal and sent to the ECM.

On Board Diagnosis Logic

UBS00DJI

The MIL will not light up for these diagnoses.

DTC Confirmation Procedure

UBS00DJJ

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 10V at idle.

 WITH CONSULT-II

1.

Turn ignition switch ON and select “DATA MONITOR” mode with
CONSULT-II.

2.

Start engine and run it for at least 5 seconds at idle speed.

3.

If 1st trip DTC is detected, go to 

EC-860, "Diagnostic Procedure"

.

 WITH GST

Follow the procedure “WITH CONSULT-II”.
