DTC P0031, P0032 HO2S1 HEATER (M/T MODELS)
PFP:22690
Description
EBS00QHR
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.
OPERATION
CONSULT-II Reference Value in Data Monitor Mode
EBS00QHS
Specification data are reference values.
On Board Diagnosis Logic
EBS00QHT
DTC Confirmation Procedure
EBS00QHU
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.
Start engine and warm it up to normal operating temperature.
2.
Turn ignition switch “OFF” and wait at least 10 seconds.

Trouble diagnosis name
DTC detecting condition
Possible cause
P0031
0031
Heated oxygen sensor 1
heater control circuit low
The current amperage in the heated oxygen sensor
1 heater circuit is out of the normal range.
(An excessively low voltage signal is sent to ECM
through the heated oxygen sensor 1 heater.)
●
Harness or connectors
(The heated oxygen sensor 1 heater
circuit is open or shorted.)
●
Heater oxygen sensor 1 heater
P0032
0032
Heated oxygen sensor 1
heater control circuit high
The current amperage in the heated oxygen sensor
1 heater circuit is out of the normal range.
(An excessively high voltage signal is sent to ECM
through the heated oxygen sensor 1 heater.)
●
Harness or connectors
(The heated oxygen sensor 1 heater
circuit is shorted.)
●

3.
Turn ignition switch “ON” and select “DATA MONITOR” mode
with CONSULT-II.
4.
Start engine and run it for at least 6 seconds at idle speed.
5.
If 1st trip DTC is detected, go to
EC-154, "Diagnostic Procedure"
.
WITH GST
1.
Start engine and warm it up to normal operating temperature.
2.
Turn ignition switch “OFF” and wait at least 10 seconds.
3.
Start engine and run it for at least 6 seconds at idle speed.
4.
Turn ignition switch “OFF” and wait at least 10 seconds.
5.
Start engine and run it for at least 6 seconds at idle speed.
6.
Select “MODE 3” with GST.
7.
If DTC is detected, go to
EC-154, "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.
