INSPECTION
FUNCTION AND OPERATION PRICIPLE
Heated Oxygen Sensor (HO2S) consists of zirconium and alumina and is installed on upstream and downstream of the
Manifold Catalyst Converter (MCC). After it compares oxygen consistency of the atmosphere with the exhaust gas, it
transfers the oxygen consistency of the exhaust gas to the PCM. When A/F ratio is rich or lean, it generates
approximately 1V or 0V respectively. In order that this sensor normally operates, the temperature of the sensor tip is
higher than 370°C (698°F). So it has a heater which is controlled by the PCM duty signal. When the exhaust gas
temperature is lower than the specified value, the heater warms the sensor tip.

29.Lifting the vehicle up and lowering the jack slowly, remove the transaxle assembly.
INSTALLATION
Installation is in the reverse order of removal.
Perform the following :
a. Adjust the shift cable.
b. Refill the transaxle with fluid.
c. Refill the radiator with engine coolant.
d. Bleed air from the cooling system with the heater valve open.
e. Clean the battery posts and cable terminals with sandpaper, assemble them, and apply grease to prevent
corrosion.
1. Lowering the vehicle or lifting up a jack, install the transaxle assembly.
2. Tighten the transaxle lower mounting bolts (B- 4EA).
TORQUE:
65~85 Nm(6.5~8.5 kgf.m, 47.0~61.5 lb - ft)
3. Install the drive plate bolts (A) by turning the timing gear.
TORQUE:
46~53 Nm(4.6~5.3 kgf.m, 33.3~38.3 lb - ft)
4.After removing a jack, insert the drive shafts. (see DS group)
5. Install the sub frame. (see SS group).
6. Tighten the roll stopper mounting bolts.
TORQUE:
90~110 Nm(9~11 kgf.m, 65.1~79.5 lb - ft)
7. Connect the lower arm, the tie rod end ball joint, the stabilizer bar link to the front knuckle. (see SS group)

TROUBLESHOOTING
PROBLEM SYMPTOMS TABLE
Before replacing or repairing air conditioning components, first determine if the malfunction is due to the refrigerant
charge, air flow or compressor.
Use the table below to help you find the cause of the problem. The numbers indicate the priority of the likely cause of
the problem. Check each part in order. If necessary, replace these parts.
After correcting the malfunction, check the complete system to ensure that performance is satisfactory.

DESCRIPTION
1.In- car air temperature sensor is located at the center facia lower panel.
2. The sensor contains a thermistor which measures the temperature of the inside. The signal decided by the
resistance value which changes in accordance with perceived inside temperature, is delivered to heater control unit
and according to this signal the control unit regulates incar temperature to intended value.
3. It perceives the inside temperature, changes the resistance value, and enters the corresponding voltage into the
automatic temperature control module.
4. It will used for discharge temperature control, sensor failsafe, temperature door control, blower motor level control,
and A/C auto control.

DESCRIPTION
1.Water temperature sensor is located at the heater unit.
2. It detects coolant temperature. Its signal is used for cold engine lockout control. When the driver operates the
heater before the engine is warmed up, the signal from sensor causes the heater control unit to reduce blower
motor speed until coolant temperature reaches the threshold value.
