P0130 2001 Toyota Corolla Code - HO2S11 Circuit Malfunction 3ZZ-FE Engine
Quick Answer
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. Common causes include Faulty Front Heated Oxygen Sensor Bank 1, Front Heated Oxygen Sensor Bank 1 harness is open or shorted, Front Heated Oxygen Sensor Bank 1 circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0130 2001 Toyota Corolla Description
(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.
What are the Possible Causes of the DTC P0130 2001 Toyota Corolla?
- Faulty Front Heated Oxygen Sensor Bank 1
- Front Heated Oxygen Sensor Bank 1 harness is open or shorted
- Front Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks
How to Fix the DTC P0130 2001 Toyota Corolla?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
