PFP:226A0
Description
EBS00QIF
SYSTEM DESCRIPTION
The ECM performs ON/OFF control of the heated oxygen sensor 2 heater corresponding to the engine speed,
amount of intake air and engine coolant temperature.
OPERATION
CONSULT-II Reference Value in Data Monitor Mode
EBS00QIG
Specification data are reference values.
On Board Diagnosis Logic
EBS00QIH
DTC Confirmation Procedure
EBS00QII
NOTE:
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 between 10.5V and 16V at
idle.
WITH CONSULT-II
1.
Turn ignition switch “ON” and select “DATA MONITOR” mode with CONSULT-II.

(Bank 1)
Heated oxygen sensor 2
heater control circuit low
The current amperage in the heated oxygen sensor
2 heater circuit is out of the normal range.
(An excessively low voltage signal is sent to ECM
through the heated oxygen sensor 2 heater.)
●
Harness or connectors
(The heated oxygen sensor 2 heater
circuit is open or shorted.)

2.
Start engine and warm it up to the normal operating temperature.
3.
Turn ignition switch “OFF” and wait at least 10 seconds.
4.
Start engine and keep the engine speed between 3,500 and
4,000 rpm for at least one minute under no load.
5.
Let engine idle for one minute.
6.
If 1st trip DTC is detected, go to
EC-175, "Diagnostic Procedure"
.
WITH GST
1.
Start engine and warm it up to the normal operating temperature.
2.
Turn ignition switch “OFF”and wait at least 10 seconds.
3.
Start engine and keep the engine speed between 3,500 and 4,000 rpm for at least one minute under no
load.
4.
Let engine idle for one minute.
5.
Turn ignition switch “OFF”and wait at least 10 seconds.
6.
Start engine and keep the engine speed between 3,500 and 4,000 rpm for at least one minute under no
load.
7.
Let engine idle for one minute.
8.
Select “MODE 3” with GST.
9.
If DTC is detected, go to
EC-175, "Diagnostic Procedure"
.
●
When using GST, “DTC Confirmation Procedure” should be performed twice as much as when
using CONSULT-II because GST cannot display MODE 7 (1st trip DTC) concerning this diagnosis.
Therefore, using CONSULT-II is recommended.

Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
