DTC P0420, P0430 THREE WAY CATALYST FUNCTIONPFP:20905
On Board Diagnosis LogicABS00C5D
The ECM monitors the switching frequency ratio of heated oxygen
sensors 1 and 2.
A three way catalyst (manifold) with high oxygen storage capacity
will indicate a low switching frequency of heated oxygen sensor 2.
As oxygen storage capacity decreases, the heated oxygen sensor 2
switching frequency will increase.
When the frequency ratio of heated oxygen sensors 1 and 2
approaches a specified limit value, the three way catalyst (manifold)
malfunction is diagnosed.
DTC Confirmation ProcedureABS00C5E
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.
WITH CONSULT-II
TESTING CONDITION:
Do not hold engine speed for more than the specified minutes below.
1. Turn ignition switch ON and select “DATA MONITOR” mode with
CONSULT-II.
2. Start engine and warm it up to the normal operating tempera-
ture.
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 1 minute under no load.
5. Let engine idle for 1 minute.
6. Make sure that “COOLAN TEMP/S” indicates more than 70°C
(158°F).
If not, warm up engine and go to next step when “COOLAN
TEMP/S” indication reaches to 70°C (158°F).
7. Open engine hood.

DTC P1146, P1166 HO2S2
Revision: 2004 November 2004 FX35/FX45
DTC P1146, P1166 HO2S2PFP:226A0
Component DescriptionABS00C9W
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 ModeABS00C9X
Specification data are reference values.
On Board Diagnosis LogicABS00C9Y
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 minimum voltage of sensor is
sufficiently low during the various driving condition such as fuel-cut.

DISASSEMBLY
NOTE:
Explained here is how to disassemble with engine stand supporting transmission surface. When using differ-
ent type of engine stand, note with difference in steps and etc.
1. Remove engine assembly from vehicle, and separate front suspension member, transmission and front
final drive from engine. Refer to EM-236, "
ENGINE ASSEMBLY" .
2. Remove the parts that may restrict installation of engine to widely use engine stand.
NOTE:
The procedure is described assuming that you use widely use engine holding the surface, to which trans-
mission is installed.
a. Remove drive plate.

Holding ring gear with ring gear stopper (SST).

Loosen mounting bolts diagonally order.
CAUTION:

Do not disassemble drive plate.

Do not place drive plate with signal plate facing down.

When handling signal plate, take care not to damage or
scratch it.

Handle signal plate in a manner that prevents it from
becoming magnetized.
b. Remove engine rear plate.
3. Lift engine with hoist to install it onto widely use engine stand.
CAUTION:
Use engine stand that has a load capacity [approximately 240kg (529 lb) or more] large enough for
supporting the engine weight.

If the load capacity of stand is not adequate, remove the following parts beforehand to reduce the
potential risk of overturning stand.

When engine coolant overflows air relief hole on heater hose,
install air relief plug.
4. Warm up engine to normal operating temperature with radiator cap installed.
5. Run engine at 3,000 rpm for 10 seconds and return to idle speed.

Repeat two or three times.
CAUTION:
Watch water temperature gauge so as not to overheat engine.
6. Stop engine and cool down to less than approximately 50°C (122°F).

Cool down using a fan to reduce the time.

If necessary, refill engine coolant up to filler neck of thermostat housing.
7. Refill reservoir tank to “MAX” level line with engine coolant.
8. Repeat steps 3 through 6 two or more times with radiator cap installed until engine coolant level no longer
drops.
9. Check cooling system for leaks with engine running.
10. Warm up engine, and check for sound of engine coolant flow while running engine from idle up to 3,000
rpm with heater temperature controller set at several position between “COOL” and “WARM”.

Sound may be noticeable at heater unit.
11. Repeat step 10 three times.
12. If sound is heard, bleed air from cooling system by repeating steps 3 through 6 until engine coolant level
no longer drops.

Clean excess engine coolant from engine.
FLUSHING COOLING SYSTEM
1. Install reservoir tank, and radiator drain plug.
If cylinder block water drain plugs are removed, close and tighten them. Refer to EM-244, "
ASSEM-
BLY" .
2. Fill thermostat housing with water until water spills from the air relief hole, then close air relief plug. Fill
thermostat housing and reservoir tank with water and reinstall radiator cap.
3. Run engine and warm it up to normal operating temperature.
4. Rev engine two or three times under no-load.
5. Stop engine and wait until it cools down.
6. Drain water from the system. Refer to MA-22, "
DRAINING ENGINE COOLANT" .
7. Repeat steps 1 through 5 until clear water begins to drain from radiator.Reservoir tank engine coolant capacity
