DTC DETECTION LOGIC
The heated oxygen sensor 2 has a much longer switching time
between rich and lean than the air fuel ratio (A/F) sensor 1. The oxy-
gen 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 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 decr eases, the heated oxygen sensor 2
switching frequency will increase.
When the frequency ratio of air fuel ratio (A/F) sensor 1 and heated
oxygen sensor 2 approaches a specif ied limit value, the three way
catalyst (manifold) malfunction is diagnosed.

CAUTION:
Apply new engine oil to parts marked in illustration before installation.
NOTE:
The following procedures explain how to disassem ble the engine with the engine stand fastened to the bell
housing. Some steps may be different if using a different type of engine stand.
DISASSEMBLY
1. Remove the engine and transaxle as an assembly from the vehicle, and separate the transaxle from the
engine. Refer to EM-84, "Removal and Installation"
.
2. Remove the drive plate. Hold the crankshaft using Tool (A) and use a suitable tool to remove the bolts.
3. Remove pilot converter using Tool.
4. Remove the rear oil seal. Refer to EM-72, "Removal and Installation of Rear Oil Seal"
.
5. Mount the engine on a suitable engine stand (A). CAUTION:
• Use an engine stand that has a load capacity large
enough for supporting the engine weight [approximately
135 kg (298 lb) or more].
• Before removing the hanging chains, check the engine
stand is stable and there is no risk of overturning.
NOTE:
The figure shows an example of widely used engine stand (A)
that can support mating surface of transaxle with drive plate
removed.
• Remove the following parts if the engine stand load capacity is not adequate, to reduce the potential risk of overturning stand:
- Intake manifold. Refer to EM-30, "Removal and Installation"
.
- Exhaust manifold. Refer to EM-33, "Removal and Installation"
.
- Rocker cover. Refer to EM-45, "Removal and Installation"
.
6. Drain any remaining engine oil and coolant from the engine.
7. Remove the exhaust manifold and three way catalyst assembly. Refer to EM-33, "Removal and Installa-
tion".
