Cars with mileage less than 80 thousand kilometers
I drove into my friend's workshop.
The owner's feedback is that the fault light is on while driving.
Moreover, the driving force becomes worse, and the acceleration is weak with jitter.
After the friend picks up the car, combine the owner's own fault description.
After the fault is confirmed.
Read the fault code of the vehicle, and the fault code will be displayed.
PO 17 1 system status is too weak.
The mechanism of this fault code is as follows
The mixture is too thick or too thin for a long time.
After the oxygen sensor monitors the signal,
It will be recorded as a fault code.
And light up the engine fault light for prompt.
The cause of failure has been determined.
What is the reason?
The experienced maintenance technician immediately asked the owner.
Did you go to some small gas stations to refuel cheaply?
Sure enough, the owner said
"I recently went back to my hometown to see the local small gas station.
Oil was cheap, so I added a box.
At first, I was fine. I ran about 50 kilometers.
The engine fault light is on. "
At this point, the cause of the failure was finally found.
Just as the technician expected.
I just went to a cheap little gas station to join.
Inferior fuel containing impurities will damage the gasoline pump.
Maintenance ideas and processes are relatively simple.
Drain the oil tank and clean the entire oil circuit.
After replacing the new gasoline pump, just test the oil pressure.
In the process of replacing the gasoline pump
It is found that there are many impurities in the filter screen in the gasoline pump.
It is precisely because of the accumulation of these impurities
Leading to the final damage of the gasoline pump.
In fact, in the major shopping malls of 4S, there are a lot of failures caused by adding inferior gasoline every year.
Some car owners may be greedy for cheap, and some car owners may have gone to remote places and have no choice.
In fact, although many gas stations are small, they are regular gas stations.
The qualifications are complete, so this kind of gas station may be cheaper, because the source of gasoline is relatively direct and the cost will be lower.
Eventually, it will be given to consumers. This kind of gas station generally has no problem with oil.
In fact, what I am most afraid of is some black workshops, without any qualifications, and the source of oil products is more complicated.
It may be through some formal channels, or it may be through some illegal channels.
For example, many people who specialize in sports cars will sell the oil in their cars to increase their income, which is a tacit source of income for their industry.
Oil bosses collect at low prices and sell them to private car owners at low prices, but they are still profitable.
In addition, some reduced operating costs due to tax evasion will eventually be reflected in oil prices.
Many riders can't help but add a box of gasoline when they see that it is much cheaper than outside. After all, it can be cheaper by tens of dollars.
You know, the approval of private gas stations is very strict.
The control of oil products is naturally very strict. Even if the price is cheap, it will not be much cheaper than two barrels of oil.
The oil price of that kind of black workshop is abnormal at first glance and there is no business license. Still enter cautiously, there is really no guarantee for oil products.
This kind of black workshop small gas station generally appears on the edge of the city or on the provincial road.
The density of regular gas stations in these areas is low, so they are given enough living space.
However, if you are greedy and cheap, and go to the black workshop to refuel, then what happened to the owner in the above case may also happen to you, and ultimately the loss outweighs the gain.

In Li Ge, rats enter the engine room during the Spring Festival. Every time I turn on the air conditioner, it smells like urine. It's not the air conditioning filtration. What should I do?
Answer?
If the air conditioner keeps smelling, there are two possibilities. One possibility is that there are mice or small animals rotting in it. I suggest you go to the repair shop as soon as possible to disassemble the blower and air duct, clean it and replace the air conditioning filter. In another case, I suggest you replace the air conditioner filter and make a simple one.
Li Ge, I'm going to buy my wife a car, a joint venture car, about 65,438+10,000 yuan. What do you recommend? thank you
Answer?
There are still many options for joint venture vehicles with a price of 654.38+ 10,000 yuan. From several angles, if you choose the appearance, the older ones will buy European, American and German cars, and the younger ones will buy Japanese and Korean cars. Japanese, Honda Fit, Nissan Sylphy and Toyota Corolla are all good choices in terms of economy and fuel economy. From the perspective of safety, brands such as LaVida in Germany can be considered. From the configuration point of view, it must be that Korean cars are relatively high in configuration, such as Kia K3, but the relative safety factor is really not high. Each has its own advantages and disadvantages, so you have to consider it yourself.
