Component DescriptionNEEC0128The heated oxygen sensor 1 is placed into the exhaust manifold.
It detects the amount of oxygen in the exhaust gas compared to the
outside air. The heated oxygen sensor 1 has a closed-end tube
made of ceramic zirconia. The zirconia generates voltage from
approximately 1V in richer conditions to 0V in leaner conditions.
The heated oxygen sensor 1 signal is sent to the ECM. The ECM
adjusts the injection pulse duration to achieve the ideal air-fuel
ratio. The ideal air-fuel ratio occurs near the radical change from
1V to 0V.

On Board Diagnosis LogicNEEC0122To judge the malfunction of heated oxygen sensor 1, this diagno-
sis measures response time of heated oxygen sensor 1 signal. The
time is compensated by engine operating (speed and load), fuel
feedback control constant, and heated oxygen sensor 1 tempera-
ture index. Judgment is based on whether the compensated time
[heated oxygen sensor 1 cycling time index] is inordinately long or
not.
