Circuit Description
In order to control emissions, a catalytic converter is used to covert harmful emissions into harmless water vapor and
carbon dioxide. The ECM has the ability to monitor this process by using a oxygen sensor. The oxygen sensor produces
and output signal which indicates the storage capacity of the catalyst. This in turn indicates the catalyst’s ability to
convert exhaust emission effectively. If the oxygen sensor pig tail wiring, connector, or terminal is damaged. Do not
attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly, it must have a clean air
reference provided to it. This clean air reference is obtained by way of the oxygen sensor wire(s). Any attempt to repair
the wires, connector, or terminal and degrade the oxygen sensor performance.

Oxygen Sensor Signal Voltage Inspection
1. Maintain the engine speed is at idle while the coolant temperature is over 80 °C.
2. Measure the oxygen sensor signal voltage between the ECM terminal No. 16 and No. 17.
Notice
If the measured value is not within the specified value, the possible cause may be in cable, oxygen sensor
or ECM.
Oxygen Sensor Heating Voltage Inspection
1. Maintain the engine speed is at idle while the coolant temperature is over 80 °C.
2. Measure the oxygen sensor signal voltage between the ECM terminal No. 11 and No. 9.
Notice
If the measured value is not within the specified value, the possible cause may be in cable, oxygen sensor
or ECM.
Oxygen Sensor Heating Current Consumption Inspection
1. Turn the ignition switch to “ON” position.
2. Measure the oxygen sensor heating current consumption between the ECM terminal No. 9 and No. 5.
Notice
If the measured value is not within the specified value, the possible cause may be in cable, oxygen sensor
or ECM.
Specified value
0.2 ~ 1.0 V
Specified value
11 ~ 14 V
Specified value
