|P0130 2002 TOYOTA COROLLA code description

In order to obtain a high purification rate for the carbon monoxide (CO), hydrocarbon (HC) and nitrogen oxide
(NOx) components in the exhaust gas, a Three-Way Catalytic Converter (TWC) is used. For the most efficient use of the TWC, the air-fuel ratio must be precisely controlled so that it is always close to the stoichio-metric air-fuel ratio.
The heated oxygen sensor has the characteristic whereby its output voltage changes suddenly in the vicinity
of the stoichio-metric air-fuel ratio. This is used to detect the oxygen concentration in the exhaust gas and
provide the ECM with feedback to control the air-fuel ratio.
When the air-fuel ratio becomes lean, the oxygen concentration in the exhaust gas increases. The heated
oxygen sensor informs the ECM of the lean condition (low voltage, i.e. less than 0.45 V).
When the air-fuel ratio is richer than the stoichio-metric air-fuel level, the oxygen concentration in the exh
aaust gas is reduced. And the heated oxygen sensor informs the ECM of the rich condition (high voltage,
i.e. more than 0.45 V). The ECM judges by the voltage output of the heated oxygen sensor whether the airfuel? ratio is rich or lean and controls the injection time accordingly. If a malfunction of the heated oxygen
sensor causes an output of abnormal voltage, the ECM is unable to perform accurate air-fuel ratio control.
The heated oxygen sensor includes a heater which heats the zirconia element. The heater is controlled by
the ECM. When the intake air volume is low (the temperature of the exhaust gas is low), a current flows to
the heater in order to heat the sensor for accurate oxygen concentration detection.
