DTC P0420, P0430 THREE WAY CATALYST FUNCTIONPFP:20905
On Board Diagnosis LogicNBS005GS
The ECM monitors the switching frequency ratio of air fuel ratio (A/F)
sensor 1 and heated oxygen sensor 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 A/F sensor 1 and heated oxygen sensor
2 approaches a specified limit value, the three way catalyst (mani-
fold) malfunction is diagnosed.
DTC Confirmation ProcedureNBS005GT
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 (158F).
7. Open engine hood.

CAUTION:
Do not disassemble drive plate.
Never 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.
3. Lift the engine with hoist to install it onto the widely use engine stand.
CAUTION:
Use an engine stand that has a load capacity [220 kg (441 lb) or more] large enough for supporting
the engine weight.
If the load capacity of the stand is not adequate, remove the following parts beforehand to reduce the
potential risk of overturning the stand.
–Remove intake manifold collector. Refer to EM-19, "INTAKE MANIFOLD COLLECTOR" .
–Remove intake manifold. Refer to EM-24, "INTAKE MANIFOLD" .
–Remove fuel injector and fuel tube assembly. Refer to EM-45, "FUEL INJECTOR AND FUEL TUBE" .
–Remove ignition coil. Refer to EM-42, "IGNITION COIL" .
–Remove rocker cover. Refer to EM-51, "ROCKER COVER" .
–Remove exhaust manifold. Refer to EM-26, "EXHAUST MANIFOLD" .
–Other removable brackets.
NOTE:
The figure shows an example of widely use engine stand that
can hold mating surface of transmission with drive plate
removed.
CAUTION:
Before removing the hanging chains, make sure the
engine stand is stable and there is no risk of overturning.
4. Drain engine oil. Refer to LU-9, "
Changing Engine Oil" .

Disassembly and AssemblyNBS004PN
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 from
engine. Refer to EM-244, "
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 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.
–Intake manifolds (upper and lower); Refer to EM-179, "INTAKE MANIFOLD" .
–Exhaust manifold and three way catalyst; Refer to EM-183, "EXHAUST MANIFOLD AND THREE WAY
CATALYST" .
