Front oxygen sensor rear oxygen sensorThe oxygen sensor in front of the three-way catalytic converter is called the front oxygen, and the rear oxygen is mounted after the three-way catalytic converter. It is generally considering that the front oxygen has a greater effect than the rear oxygen, because the front oxygen is used to adjust the density of the mixed gas, and the rear oxygen is to monitor the working condition of the three-way catalytic converter. Oxidation reaction will occur when the three-way catalytic converter is working, such as CO+02=CO2, which means that the oxygen content monitored by the rear oxygen is less than that of the front oxygen. Otherwise, the three-way fails or the purification capacity decreases, a few vehicles will light up the fault light, prompting the owner to check or replace the catalyst.
Rear oxygen sensor damage symptoms:Engine fault light on: Similar to when the front oxygen sensor is damaged, the engine fault light on the dashboard may light up.
There is a rumbling sound from the engine exhaust: The exhaust system may make abnormal noises.
Strong and unpleasant smell: The smell in the exhaust may be stronger.
Increased fuel consumption: Fuel economy will also deteriorate.
Vehicle shaking: The vehicle may shake during driving, and there may be a jerk when shifting gears.
Insufficient power: The engine power is weakened and the acceleration is slow.
The car is frustrating, accelerating slowly, and can''''t run: These symptoms may be related to the damage of the rear oxygen sensor.
