P0139 HO2S2
DescriptionINFOID:0000000001670936
The heated oxygen sensor 2, after three way catalyst (manifold),
monitors the oxygen level in the exhaust gas on each bank.
Even if switching characteristics of the heated oxygen sensor 1 are
shifted, the air-fuel ratio is controlled to stoichiometric, by the signal
from the heated oxygen sensor 2.
This sensor is made of ceramic zirconia. The zirconia generates volt-
age from approximately 1V in richer conditions to 0V in leaner condi-
tions.
Under normal conditions the heated oxygen sensor 2 is not used for
engine control operation.
DTC LogicINFOID:0000000001670937
DTC DETECTION LOGIC
The heated oxygen sensor 2 has a much longer switching time
between rich and lean than the heated oxygen sensor 1. The oxygen
storage capacity of the three way catalyst (manifold) causes the
longer switching time. To judge the malfunctions of heated oxygen
sensor 2, ECM monitors whether the switching response of the sen-
sor's voltage is faster than specified during the various driving condi-
tion such as fuel-cut.
DTC CONFIRMATION PROCEDURE
1.INSPECTION START
Do you have CONSULT-III?
Do you have CONSULT-III?
YES >> GO TO 2.
NO >> GO TO 11.
2.PRECONDITIONING
“COMPLETED” will appear on CONSULT-III screen when all tests “COND1”, “COND2” and “COND3” are
completed.
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
For the best results, perform DTC WORK SUPPORT at a temperature of 0 to 30°C (32 to 86°F).
Never stop engine during this procedure. If the engine is stopped, retry this procedure from PERFORM PRO-
CEDURE FOR COND1 - II.

5.PERFORM PROCEDURE FOR COND1-III
1. Start engine and keep the engine speed between 3,500 and 4,000 rpm for at least 1 minute under no load.
2. Let engine idle 1 minute.
3. Select “HO2S2 (B1) P0139” of “HO2S2” in “DTC WORK SUPPORT” mode with CONSULT-III.

“CONPLETED” appears on CONSULT-III screen?
YES >> GO TO 9.
NO >> GO TO 6.
6.PERFORM PROCEDURE FOR COND1-IV
When the following conditions are met, “TESTING” will be displayed at “COND1” on the CONSULT-III screen.
Maintain the condition continuously until “TESTING” changes to “COMPLETED” (It will take approximately 60
seconds.)
Which displayed on CONSULT-III screen?
COND1: OUT OF CONDITION>>GO TO 4.
COND1: COMPLETED COND2: INCOMPLETED>>GO TO 7.
COND1: COMPLETED COND2: COMPLETED>>GO TO 8.
7.PERFORM PROCEDURE FOR COND2
While driving, release accelerator pedal completely from the above condition until “INCOMPLETED” at
“COND2” on CONSULT-III screen has turned to “COMPLETED”. (It will take approximately 4 seconds.)
Which displayed on CONSULT-III screen?
COND2: COMPLETED COND3: INCOMPLETED>>GO TO 8.
COND2: COMPLETED COND3: COMPLETED>>GO TO 9.
