The golf sensor is broken. Is it serious?

If only the oxygen sensor is broken, it will not affect the driving of the car.

I'll tell you a case for your reference.

Golf GTI oxygen sensor is broken. After the yellow fault light came on, I didn't pay attention to driving and found that the fuel consumption was too high. Finally, I replaced the new oxygen sensor. The fault light disappeared and the fuel consumption recovered little by little.

Sensor fault analysis Many cars' oxygen sensors100000 kilometers or more will not break down. Sensors are actually electronic accessories, and there is generally no problem. This accessory is like a computer accessory. It will not be damaged unless it is disturbed by external factors. In addition, many damaged oxygen sensors will not report faults normally, because the damaged sensors can't detect the fault data of poor emission, and the natural fault light will not light up. The principle of fault repair of oxygen sensor is as follows: the fault code of oxygen sensor will only be reported to the fault lamp after it has been detected that the combustion is not good for many times and accumulated to a certain number of times. Therefore, when the sensor can report the fault light, it actually means that the sensor is not broken, and the broken sensor will not report the combustion data fault. Therefore, it is an expedient measure to replace the new oxygen sensor, but the fault light cannot be realized within a time difference, and soon the fault light will light up again.

Because the oil circuit is not cleaned, only the sensor is replaced, so each new sensor will have a time difference, accumulate the time difference of fault data flow, and finally report the fault light.

The solution to this situation is that it is not enough to replace the oxygen sensor, because the root cause of this situation is poor combustion.

Clean up as early as possible to prevent excessive carbon deposition caused by poor continuous combustion. As long as there is inferior fuel, it will continue to pollute fresh fuel. Therefore, as soon as possible, follow the rider's method in the rider circle: thoroughly clean the oil circuit with Siyoupu additive for 4 times. There will be no fault light after the oil circuit is cleaned and burned, and there will be no fault light of the sensor when the oil circuit is cleaned frequently. Long-term poor combustion will lead to serious phenomena such as excessive carbon deposition, idling jitter, insufficient power and engine oil explosion. ? If the combustion is not good for a long time, the spark plug will naturally damage quickly. ?
