May I ask what is the reason that the car is out of gas, but the fuel gauge indicator on the dashboa

If the meter indicator light is not on, first check the power supply fuse of the dashboard.

If the circuit breaker. will need to be replaced. Disassemble the dashboard, the lights are generally at the back of the dashboard, replace the lights that are not lit, and generally the individual lights are not lit to indicate that there is no problem with the fuse and wire, the main reasons are as follows

1. The lamp of the dashboard is damaged and needs to be replaced in time;

2. If the power supply line of the dashboard is broken, there will be an open circuit or a short circuit, which will also lead to the car dashboard.

There is no light up;

3. If the power supply fuse of the car dashboard is broken, there will naturally be no power supply, and the dashboard will not light up.

Precautions in the use of the car dashboard:

1. When the indicator light is on, the odometer should be observed immediately, if the cumulative mileage reaches or exceeds l00,000km, the timing toothed belt must be replaced, otherwise the timing toothed belt may break, so that the engine can not work normally.

2. After replacing the new timing toothed belt, it is necessary to open the rubber plug outside the reset switch on the mileage dial, and press the reset switch inside with a small round bar to extinguish the indicator light of the timing toothed belt.

3. After replacing the new timing toothed belt, remove the odometer and adjust all the readings on the odometer to the 0 position.

This is often caused by a problem with the fuel sensor, which is inside the fuel tank.

Design principles. 1. The fuel tank must have a large enough volume. On the one hand, it should meet the requirements of heat dissipation as much as possible, and on the other hand, it should be able to accommodate all the working media in the system when the hydraulic system is stopped working, and maintain the appropriate liquid level when working.

2. The suction pipe and the oil return pipe should be inserted below the minimum liquid level to prevent bubbles caused by air suction and oil return splashing. The distance between the nozzle and the bottom and wall of the box is generally not less than 3 times the diameter of the pipe.

The suction pipe can be installed with a mesh or line gap filter of about l00 m, and the installation position should be convenient for loading, unloading and cleaning the filter. The return nozzle should be beveled to 45°. The corners are also facing the tank wall to prevent the oil return from hitting the deposits at the bottom of the tank and also to facilitate heat dissipation.

Every time you drive, you should develop a good habit and double-check the safety status of your vehicle.

1. Check whether the vehicle oil, brake oil, gasoline and cooling water are normal; Whether there is leakage.

2. Check whether the vehicle braking system is intact and effective; whether the air pump and air reservoir are leaking; whether the tire pressure is normal; whether the tyre fastening screws are loose; Whether the spare tire is in good condition.

3. Check whether the vehicle direction lights, brake indicators, lights, wipers, and horns are normal.

4. Check whether the steering system of the vehicle is intact and reliable.

5. Record the inspection situation, report and repair the problem in time, and strictly prohibit the "sick car" from appearing.

The yellow light of the fuel meter is just a warning, and the red light indicates that the fuel tank is about to run out of gas, because the product designer takes into account that some people do not look at the fuel meter when driving, so they design such a prompt light, so the fuel tank lights up the alarm light and then go to refuel is the default of the manufacturer, and there is no big problem, and the cruising range of 50 kilometers after the fuel meter is lit also meets the needs of finding gas stations and oil pump heat dissipation.

But it is still not recommended to refuel when the red light of the fuel tank is on, first of all, in the case of less fuel, intense driving will affect the work of the fuel pump because of the large rollover of the vehicle. The second is that after the fuel level alarm, it is not certain whether the gas station can be found within the range (at high speeds). In addition, refueling after the fuel level alarm light is on is limited to finding the gas station for a short distance, and there is a risk of damaging the fuel pump and fuel level sensor if it is far away.

If the car gasoline is out of oil, the fuel level warning light is not lit in general, there is a problem with the electronic sensor circuit, check the circuit first, if there is no problem, it is the oil level float level gauge that is stuck, and it cannot change with the change of oil level, resulting in the alarm light not lighting.

You can try again, if it is still like this, it is that the oil mark sensor is broken.

The reason for the abnormal display of the car fuel gauge is generally caused by the failure of the oil float (oil level display sensor). The fuel gauge is used by a float to detect the oil level, and this problem will occur if the detection signal is distorted. Some oil level displays are computer-controlled, and computer signal failure may also lead to inaccurate display, which is very low.

How to look at the car fuel gauge.

In the car fuel tank, it is composed of a float connected to a metal rod, and the basic principle is the same as the float principle of the toilet tank in your own home. When the water level is lowered, the float position will also be lowered with the progress, and then a connecting rod will be driven to start the water injection port so that the water can be injected in, and the float position will also rise when the water level is raised, and when it reaches a certain extent, the connecting rod will close the water injection port.

The measuring unit of the fuel gauge also makes use of this very simple and crude, very practical method, but the tail end of the metal rod connected to the float will be connected to a variable resistance through a movable contact, and the change of the position of the float on the oil surface in the fuel tank will also change the position of the wiper on the variable resistance through the metal rod, and this variable resistance will be connected to the fuel gauge of the car, and the action of the fuel gauge pointer will be controlled by the amount of current through the variable resistor. When the fuel tank is full, the float metal rod wiper will make the resistance value of the variable resistance very low, the electric gate will also open the conduction current is large, the pointer of the fuel gauge will jump high, pointing to f, when the fuel tank is empty, the float metal rod wiper will make the resistance value of the variable resistance higher, the current amount of conduction will also decrease, and the pointer of the fuel gauge will be lowered, pointing to e.

The car is driving and the fuel gauge suddenly shows that there is no gas, which may be caused by the problem of the fuel tank float of the car, which is to check to see if there is an oil leakage problem in the fuel tank of the car.

The car drove and the fuel gauge showed that there was no gas, and one was really out of gas. Then the fuel gauge is broken, and the third is that the gasoline sensor in the fuel tank is broken or broken.

It should be that the oil level sensor is stuck in a certain position, or it is not in good contact at a certain position.

It is recommended to replace or repair the oil level sensor to reduce potential safety hazards.

An oil level sensor that detects the position (height) of oil in the container by using the change in capacitance between the sensor housing and the sensing electrode caused by the oil entering the container, and converting this change into a change in current.

When you drive without fuel, you must first determine whether there is oil in the fuel tank, and if there is oil in the tank, check whether the oil float has a signal. Then check the signal of the meter, is there a problem with the meter if there is a problem?

In a situation like this, there must be a problem with the fuel sensor, and this problem is easy to solve, you can go to the car repair shop for targeted repairs, whether to replace the guide sensor with a new meter sensor, and then the problem can be solved immediately.

The main reasons why the car dashboard light does not light up are as follows:

1.Instrument panel lighting is damaged;

2.The power supply wire of the instrument panel is disconnected;

3.The power supply fuse of the instrument panel is blown out; The problem can be solved by mainly examining the above aspects. First of all, check the power supply fuse of the dashboard, if it is blown can be replaced; Disassemble the instrument panel, the lights are generally at the back of the dashboard, and replace the lights that are not on.

Generally, if the individual lights do not turn on, it means that there is no problem with the fuse and wire.

If the car instrument light does not light up, it is recommended to go to a regular repair shop for repair.

Possible problems: 1. There is a discharge fault in the vehicle, resulting in excessive electrostatic current in the body.

2. The use of modified high-voltage electricity, ignition coils, and spark plugs leads to interference with high ignition intensity of the engine.

3. Install high-power electrical equipment without permission, resulting in unstable circuit voltage of the whole vehicle.

4. Humid interior environment, such as the internal circuit board of the instrument is affected by moisture after car washing, and there is poor contact or short circuit.

Solution: 1. Unplug the rear of the meter. After unplugging, place the meter in a slightly higher dry location as much as possible, such as in sunlight, heating, etc. Store for about half an hour. Allow its internal circuit board and plugs to dry well. Completely eliminates static build-up.

2. If the car battery is out of power, the car will show symptoms such as the dashboard lights not lighting, the car lights dimming, and the horn not ringing. In this case, the car battery should be checked and charged in time, and if the battery is damaged, a new battery can be replaced.

Check whether the fuse of the instrument is burned or the plug is loose, if not, it may be the cause of the dashboard

Hello, the car fuel gauge light is not on, you need to check whether the fuel level is normal, if the fuel level is normal, the fuel gauge light will not turn on. If there is no gas, the gasoline does not shine, it is generally a problem with the wiring or the oil float in the fuel tank is damaged.

The meter in the middle can be displayed normally.

If the yellow backlight in the middle is not bright, it may be that the backlight source is damaged, and how long has you bought the car.

4S should still be guaranteed.

If it's just backlit, wait until you have time to go for 4s

Just take a look at it.

The first is to check the condition of the fuse supplied by the dashboard, if the fuse is blown out, you can replace the fuse by yourself. 2/4

If you rule out the problem with the fuse, or if you can't solve it yourself, you should go to the nearest 4S shop or auto repair shop for maintenance. 3/4

Disassemble the dashboard, the lights are generally at the back of the dashboard, replace the lights that are not lit, if the power supply wire of the dashboard is broken, you can only replace it with a new one. 4/4

If there is a broken circuit fault in the dial line, it will cause the instrument to be unable to be powered normally, causing the light not to light up.

Summary. There are so many reasons for this. Suddenly, the engine stopped while driving, and the fuel gauge light didn't come on.

We don't blame all the problems on oil depletion. If it's really related to the oil, then check the gasoline pump and gasoline filter to see if the gasoline pump is broken or the gasoline filter is clogged. The gasoline pump is easy to check.

Turn on the ignition again after turning off the ignition. At this point, the gasoline pump will work for 3 seconds. In the quiet environment, you can clearly hear the hum of the oil pump.

If you can't hear it, the oil pump is not working. Then, it is necessary to further confirm whether it is a safe burnout or a broken oil pump motor.

The car has oil, the fuel gauge shows no oil, and it can't be started for any reason.

Hello dear!! I'm glad to answer for you. The car has oil, the fuel gauge shows no oil, and it can't start for the following reasons:

1. If the real beam hole is out of oil, it must be a leak in the fuel tank 2. If the fuel gauge is alarmed, but the fuel tank is full, then there can be a delay in the oil level gauge ring, or it may be a line problem 3, the fuel gauge is not lit, but the engine suddenly stalled.

There are too many reasons for this Qi to accompany the uproar. Suddenly, the engine stopped while driving, and the fuel gauge light didn't come on. We don't blame all the problems on oil depletion.

If it's really related to the oil, then check the gasoline pump and gasoline filter to see if the gasoline pump is broken or the gasoline filter is clogged. The gasoline pump is easy to check. Turn on the ignition again after turning off the ignition.

At this time, the gasoline pump will work for 3 seconds. In the quiet environment, you can clearly hear the hum of the oil pump. If you can't hear it, the oil pump is not working.

Then, it is necessary to further confirm whether it is a safe burnout or a broken oil pump motor.

Suddenly the fire went out, and the fuel gauge also showed zero, why can't it catch fire?

All tanks will have a "dead oil level" left in it, and it will not be able to suck in. Because there is inevitably a small amount of water in the oil, after a long time, the plum socks will always be deposited at the bottom of the fuel tank, if the oil is sucked from the bottom of the fuel tank, it will absorb the water early and the ridge will return, affecting the operation of the car. As a result, there is a small amount of liquid left at the bottom of the tank, not necessarily oil!

Most of them are oil-water mixtures. Which wild excited.

I added one hundred and fifty dollars to get oil.

The fuel gauge is still zero.

There are many reasons why the car cannot catch fire after the sudden shutdown, generally: the spark plug is broken, the fuel pump is faulty, the injector is blocked or leaking, the fuel quality is not good, the engine has too much hail carbon, the timing belt is broken, the water temperature sensor is faulty, etc., it is best to contact the 4 s shop for further inspection to eliminate the fault of the wax stove.

If the oil has been depleted, that is, the oil in the tank is gone, then the fuel gauge needle will not move. However, the fuel gauge light will still be on, and it will start to light up when you have 50 kilometers left to run (usually 50 kilometers) to remind you to go to the nearest place to refuel.

However, there are also times when the fuel gauge pointer fails, and the fuel gauge and the alarm light work by the signal provided by the oil level sensor (that is, the oil float). But it's hard to say whether the two are a system, if it's a system, the watch is broken, and the lamp won't work.

If it is two systems, the light will work as long as the fuel level sensor is normal. Regardless of whether it is a system or not, as long as the fuel level sensor is broken, neither will work. The easiest way to judge is the replacement method, find a normal oil level sensor and try it.

Repair: Previously, it was possible to fill up the tank every few hundred kilometers.
