DESCRIPTION
1.Engine is hard to start or does not start at all.
2. Unstable idle.
3. Poor driveability
If any of the above conditions are noted, first perform a routine diagnosis that includes basic engine checks (ignition
system malfunction, incorrect engine adjustment, etc.). Then, inspect the Gasoline Engine Control system components
with the HI- SCAN (Pro).
a. Before removing or installing any part, read the diagnostic trouble codes and then disconnect the battery
negative ( - ) terminal.
b. Before disconnecting the cable from battery terminal, turn the ignition switch to OFF. Removal or connection
of the battery cable during engine operation or while the ignition switch is ON could cause damage to the
ECM.
c. The control harnesses between the ECM and heated oxygen sensor are shielded with the shielded ground
wires to the body in order to prevent the influence of ignition noises and radio interference. When the shielded
wire is faulty, the control harness must be replaced.
d. When checking the generator for the charging state, do not disconnect the battery '+' terminal to prevent the
ECM from damage due to the voltage.
e. When charging the battery with the external charger, disconnect the vehicle side battery terminals to prevent
damage to the ECM.

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.
