OXYGEN SENSOR
1 Electricity Wire
2 Oxygen Sensor Housing
3 Sensor Ceramic
4 Electrode (Internal)
5 Electrode (External)
6 Heating Coil
7 Open Space
8 Protector Tube
Functions
The oxygen sensor optimizes the combustion (Air-Fuel Ratio
14.7:1) and resets the Air-fuel ratio in the ECU after sensing
the amount of oxygen from the exhaust gases to diminish the
exhaust gases.
- Rich(<1) above approx. 450mV
- Lean(>1) below approx. 450mV
Locatoin of Sensor
Oxygen sensor is located on the front exhaust pipe.

Oxygen Sensor Signal Voltage Inspection
1. Measure the oxygen sensor signal voltage between the ECU
terminal No.11 and No.9. Maintain the engine speed ia at
idle while the coolant temperature is over 80°C.
If the measured value is not within the specified value, the
possible cause may be in cable, oxygen sensor or ECU.
Oxygen Sensor Heating Voltage Inspection
1. Measure the oxygen sensor heating voltage between the
ECU terminal No.11 and No.9. Maintain the engine speed ia
at idle while the coolant temperature is over 80°C.
If the measured value is not within the specified value, the
possible cause may be in cable, oxygen sensor or ECU.
Oxygen Sensor Heating Current Consumption
Inspection
1. Measure the oxygen sensor heating current consumption
between the ECU terminal No.9 and No.5 while the ignition
switch is in "ON" position.
If the measured value is not within the specified value, the
possible cause may be in cable, oxygen sensor or ECU.
