Check the voltage when revving up to 4,000 rpm under no load
at least 10 times.
(Depress and release accelerator pedal as soon as possible.)
The voltage should be above 0.68V at least once during this
procedure.
If the voltage is above 0.68V at step 6, step 7 is not neces-
sary.

PFP:226A0
Component Description
EBS00QRA
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.
CONSULT-II Reference Value in Data Monitor Mode
EBS00QRB
Specification data are reference values.
On Board Diagnosis Logic
EBS00QRC
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 maximum voltage of the sensor
is sufficiently high during the various driving condition such as fuel-
cut.

DTC Confirmation Procedure
EBS00QRD
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
●
“COMPLETED” will appear on CONSULT-II 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:
Never stop engine during this procedure. If the engine is stopped, retry procedure from step 2 in “Pro-
cedure for COND1”
WITH CONSULT-II
Procedure for COND1
For the best results, perform “DTC WORK SUPPORT” at a temperature of 0 to 30
°
C (32 to 86
°
F).
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.
Select “HO2S2 (B1) P1147” or “HO2S2 (B2) P1167” of “HO2S2” in “DTC WORK SUPPORT” mode with
CONSULT-II.
6.
Touch “START”.
7.
Let engine idle for at least 30 seconds.
8.
Rev engine up to 2,000 rpm 2 or 3 times quickly under no load.
If “COMPLETED” appears on CONSULT-II screen, go to step 2 in “Procedure for COND3”.
If “COMPLETED” does not appear on CONSULT-II screen, go to the following step.
9.
When the following conditions are met, “TESTING” will be displayed at “COND1” on the CONSULT-II
screen. Maintain the conditions continuously until “TESTING” changes to “COMPLETED”. (It will take
approximately 60 seconds.)
NOTE:
●
If “TESTING” is not displayed after 5 minutes, retry from step 2 in Procedure for COND1”.
●
If “COMPLETED” already appears at “COND2” on CONSULT-II screen before “Procedure for
COND2” is conducted, it is unnecessary to conduct step 1 in “Procedure for COND2”.

Procedure for COND2
1.
While driving, release accelerator pedal completed with “OD”
OFF from the above condition [step 9] until “INCOMPLETE” at
“COND2” on CONSULT-II screen has turned to “COMPLETED”
(It will take approximately 4 seconds.)
NOTE:
If “COMPLETE” already appears at “COND3” on CONSULT-
II screen before “Procedure for COND3” is conducted, it is
unnecessary to conduct step 1 in “Procedure for COND3”.
Procedure for COND3
1.
Stop vehicle and let it idle until “INCOMPLETE” of “COND3” on
CONSULT-II screen has turned to “COMPLETED”. (It will take a
maximum of approximately 6 minutes.)
2.
Make sure that “OK” is displayed after touching “SELF-DIAG
RESULTS”.
If “NG” is displayed, refer to
EC-466, "Diagnostic Procedure"
.
If “CAN NOT BE DIAGNOSED” is displayed, perform the follow-
ing.
a.
Turn ignition switch “OFF” and leave the vehicle in a cool place
(soak the vehicle).
b.
Turn ignition switch “ON” and select “COOLANTEMP/S” in
“DATA MONITOR” mode with CONSULT-II
c.
Start engine and warm it up while monitoring “COOLANTEMP/S” indication on CONSULT-II.
d.
When “COOLANTEMP/S” indication reaches to 70
°
C (158
°

COOLING FAN CONTROL
*1: The ECM determines the start signal status by the signals of engine speed and battery voltage.
*2: These signals are sent to the ECM through CAN communication line.
The ECM controls the cooling fan corresponding to the vehicle speed, engine coolant temperature, refrigerant
pressure, and air conditioner ON signal. The control system has 2-step control [ON/OFF].
The ECM sends a cooling fan control signal to the smart entrance control unit through CAN communication
line, and the smart entrance control unit controls cooling fan relays.

DTC P1217 ENGINE OVER TEMPERATURE
On Board Diagnosis Logic
EBS00QRT
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise. When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction
is indicated.
This self-diagnosis has the one trip detection logic.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to “Changing Engine Coolant”,
LC-18. Also, replace the engine oil. Refer to “Changing Engine Oil”, LC-8.
1.
Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to “Engine Coolant Mixture Ratio”, MA-15.
2.
After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function Check
EBS00QRU
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.
WITH CONSULT-II
1.
Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to
.
2.
Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to
.
