Component DescriptionEBS00K5R
The 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.
CONSULT-II Reference Value in Data Monitor ModeEBS00K5S
Specification data are reference values.
On Board Diagnosis LogicEBS00K5T
To judge the malfunction of heated oxygen sensor 1, this diagnosis
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 temperature index.
Judgment is based on whether the compensated time (heated oxy-
gen sensor 1 cycling time index) is inordinately long or not.
