Product Description
The correct installation of automobile oxygen sensor is the key to ensure the normal operation of engine and the emission of exhaust gas meet the environmental protection standards. The following are the installation steps of the automobile oxygen sensor:
1. Determine the position of the sensor: First, determine the installation position of the oxygen sensor according to the specific model and engine type of the vehicle. Usually, cars are equipped with front oxygen sensors and rear oxygen sensors, which are located at the front and rear of the exhaust pipe respectively.
2. Dismantle the old sensor: Before replacing the oxygen sensor, you need to lift the vehicle to find the position of the old sensor. Use appropriate tools to remove the old sensor, ensuring that the sensor circuit and connection port are not damaged during removal.
3. Install the new sensor: Insert the new oxygen sensor into the sensor installation hole, and ensure that the connection ports are correctly aligned and fastened. According to the regulations of the vehicle manufacturer, use the correct torque to fix the sensor in position to avoid looseness or air leakage.
4. Wiring: Connect the wiring of the oxygen sensor to the electrical system of the vehicle to ensure that the connection is firm and will not be loose. Check whether the line is connected correctly to avoid short circuit or poor contact.
5. Testing and adjustment: After the installation is completed, start the engine for testing to ensure that the sensor works normally. Use diagnostic tools to detect the working state of the oxygen sensor, adjust the position and circuit of the sensor, and ensure that the sensor accurately reads the oxygen content in the exhaust gas.
6. Clear fault codes: After installation, use diagnostic tools to clear possible fault codes, restart the engine, and ensure that the fault indicator light goes out.
Proper installation of automobile oxygen sensor needs to pay attention to the details such as installation position, connection line and fixed torque to ensure the normal and stable operation of the sensor. If you are not familiar with the operation of automobile maintenance, it is recommended to seek the help of professional technicians or automobile repair shops for installation.
