DTC LogicINFOID:0000000003856631
DTC DETECTION LOGIC
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 PROCEDURE
1.INSPECTION START
Will CONSULT-III be used?
Will CONSULT-III be used?
YES >> GO TO 2.
NO >> GO TO 7.
2.PRECONDITIONING
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:
Do not hold engine speed for more than the specified minutes below.
>> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE-I
With CONSULT-III
1. Turn ignition switch ON and select “DATA MONITOR” mode with CONSULT-III.
2. Start engine and warm it up to the normal operating temperature.
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. Check 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.
8. Select “DTC & SRT CONFIRMATION” then “SRT WORK SUPPORT” mode with CONSULT-III.
9. Rev engine between 2,000 and 3,000 rpm and hold it for 3 consecutive minutes then release the acceler-
ator pedal completely.
10. Check the indication of “CATALYST”.

SettingINFOID:0000000003802278
NOTE:
Explained here is how to disassemble with engine stand supporting transaxle surface. When using different
type of engine stand, note with difference in steps and etc.
1. Remove the engine assembly from the vehicle. Refer to EM-67, "
Exploded View".
2. Remove the parts that may restrict installation of engine to widely use engine stand.
NOTE:
The procedure is described assuming that you use a widely use engine stand holding the surface, to
which transmission is installed.
 Remove drive plate. Fix crankshaft pulley with the pulley holder (commercial service tool), and remove
mounting bolts.
 Loosen mounting bolts in diagonal order.
 Check for deformation or damage drive plate.
CAUTION:
 Never 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. Remove pilot converter using the pilot bushing puller (SST) as
necessary.
4. 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 (485 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-28, "
Exploded View".
- Remove intake manifold. Refer to EM-32, "
Exploded View".
- Remove fuel injector and fuel tube assembly. Refer to EM-44, "
Exploded View".
- Remove ignition coil. Refer to EM-49, "
Exploded View".
- Remove rocker cover. Refer to EM-49, "
Exploded View".
- Remove exhaust manifold. Refer to EM-34, "
Exploded View".
- Other removable brackets.
