Product Description
Automobile rear oxygen sensor and front oxygen sensor usually have the following differences in appearance:
1. Shell shape: The shell shape of the front oxygen sensor and the rear oxygen sensor may be different. The front oxygen sensor is usually small and slender, and the housing is usually made of metal or ceramic, and sometimes there is a protective cover. The rear oxygen sensor is usually large and round, and the shell is usually made of metal, and sometimes there is a protective cover.
2. Interface type: The interface types of the front oxygen sensor and the rear oxygen sensor may also be different. The interface of the front oxygen sensor is usually socket type or screw type, which is used to connect to the upstream position of the engine exhaust manifold. The interface of the rear oxygen sensor is usually threaded and used to connect to the downstream position of the exhaust pipe.
3. Sensor location: Another difference in appearance is the installation location of the sensor. The front oxygen sensor is usually installed upstream of the engine exhaust manifold, and the rear oxygen sensor is usually installed downstream of the exhaust pipe.
Generally speaking, the difference in appearance between automobile rear oxygen sensor and front oxygen sensor is mainly reflected in the shape of shell, interface type and installation position. These differences in appearance reflect their different functions and roles in vehicle emission control system. When replacing or repairing the oxygen sensor, it is necessary to select the appropriate sensor according to the specific situation of the vehicle and the installation position of the sensor.
