DescriptionINFOID:0000000001161789
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.
DTC LogicINFOID:0000000001161790
DTC DETECTION LOGIC
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.

DescriptionINFOID:0000000001161801
The heated oxygen sensor 2, after three way catalyst (manifold),
monitors the oxygen level in the exhaust gas on each bank.
Even if switching characteristics of the heated oxygen sensor 1 are
shifted, the air-fuel ratio is controlled to stoichiometric, by the signal
from the heated oxygen sensor 2.
This sensor is made of ceramic zirconia. The zirconia generates volt-
age from approximately 1V in richer conditions to 0V in leaner condi-
tions.
Under normal conditions the heated oxygen sensor 2 is not used for
engine control operation.
DTC LogicINFOID:0000000001161802
DTC DETECTION LOGIC
The heated oxygen sensor 2 has a much longer switching time between rich and lean than the heated oxygen
sensor 1. The oxygen storage capacity of the three way catalyst (manifold) causes the longer switching time.
To judge the malfunctions of heated oxygen sensor 2, ECM monitors
whether the voltage is unusually high during the various driving con-
dition such as fuel-cut.
