What is the reason why the fuel gauge does not respond when I add oil?

The reasons why the car fuel gauge does not move are roughly divided into four categories, 1. The plug of the oil level sensor falls off, and the oil level sensor is what we often call the oil float. 2. The battery power of the car is too low. 3. Lack of lubrication of the fuel gauge pointer. 4. There is a problem with the fuel gauge line.

When the oil meter does not move, there are corresponding solutions, first of all, the best is to go to a professional maintenance organization for problem inspection and repair. Secondly, if the situation is urgent, we can also solve it by ourselves, if the oil float falls off, we only need to plug it back in; If the battery is out of power, we need to charge the battery immediately to avoid unnecessary trouble; Finally, you can check the fuel gauge pointer, if there is a lack of lubrication, apply lubricating oil to the oil gauge pointer.

2.If the throttle is closed at this time, the jitter will decrease or disappear, and the speed of the vehicle will change with the degree of damage to the faulty part when the fault occurs;

3.In most cases, this is caused by pitting at the point where the inner wall of the inner cage is often in contact with the outer skin of the needle roller bearing, i.e. where the torque is transmitted (stress point). So first, check if the left and right half shafts are bent.

Secondly, disassemble and check whether there is wear and pitting on the inner walls of the left and right inner cages.

When the vehicle accelerates rapidly, because there is a certain angle between the axial direction of the half shaft and the axial direction of the inner cage, in the process of cage rotation, the stress point constantly changes back and forth along the axial direction, and the force generated by this change continuously pushes the body to the left and right sides, thereby causing the phenomenon of shaking.

Under the action of long-term torsional fatigue and impact force, the half shaft of the automobile is prone to bending, torsion and fracture, and its spline teeth are worn or twisted, resulting in the car accelerating to a certain speed range, the front of the car shakes regularly, and the shake disappears or decreases after releasing the accelerator.

The problem is most likely with the engine running. If the engine needs to work, it must have enough air gas, enough gasoline and an ignition system in good working order. On the one hand, any problem can cause the engine to shake.

In engine ignition systems, ignition high-voltage wires usually have few problems, so the main problems are the ignition coils and spark plugs. Because they are all consumable parts, when the performance of the spark plug is reduced or when an inferior spark plug is used, the car will not be able to accelerate the jitter.

The fuel system of a car is relatively large and has many parts, and an abnormality or failure of one of the components will cause the engine of the car to shake when accelerating.

For example, excessive carbon build-up on the throttle, faulty injectors, faulty gasoline pumps, clogged gasoline filters, and so on.

In general, body shaking is not a trivial matter. Unless it is a normal frustration, you should go to a professional repair shop or 4S shop for repairs immediately.

If the pointer does not move after just filling up the oil, the oil float is not moving, that is, the oil float is buoyant by the buoyancy of the oil on the top of the fuel tank, and the pointer connected to the sensor does not move, when a little fuel is consumed, the oil float falls, and the pointer will move with the sensor.

If the pointer of the oil gauge does not move, the oil float is generally broken. If the pointer does not move after just filling up the oil, that is, the oil float is pushed on the top of the fuel tank by the buoyancy of the oil, and the pointer connected to the sensor will not move.

First of all, we understand how the oil gauge shows the amount of oil, it is connected to a metal rod through a float in the fuel tank, this principle is similar to the toilet tank in the bathroom, the tail end of the metal rod connected to the float will be connected to a variable resistance through a movable contact, the change in the position of the float on the oil surface in the fuel tank will also change the position on the variable resistance through the metal rod, and this variable resistance will be connected to the oil gauge of the car. The movement of the fuel gauge pointer is controlled by the amount of current through a variable resistor.

If it's a bit old, it's likely to be a problem with the oil float, which is what we call the oil level sensor. Then we can check whether the oil level sensor plug on the fuel tank is loose and whether it is oxidative ablation; Observe whether there is any stagnation during the slippage process of the oil level sensor.

If there is no problem with the oil level sensor, then it is likely that there is a problem with the fuel gauge line of the dashboard, at this time, the instrument panel should be removed, and the multimeter and pin should be used to find the corresponding fuel gauge line on the instrument for detection.

If the fuel gauge of the new car suddenly drops to zero, and then does not move, then it means that there is a problem with the sensor and can be replaced directly with the 4S shop.

1. One is the instrument is damaged, the second is the line, the third is the oil float is damaged, first detect whether the oil float line live wire and the iron wire are normal, if not, check the line, if the oil float is removed normally, move it up and down by hand. If it moves, the oil float is damaged, and if it doesn't move, check the oil gauge.

2. Turn the key on and off again. If the switch still doesn't work, it is recommended to run for a period of time to see, run for a while and it still doesn't work, it is recommended to replace the oil float.

3. It depends on what kind of car it is, and some cars have a slow oil gauge to rise. It may take five or six minutes for it to get back into place, and it's usually mostly electronic.

Precautions for use.

Because the gasoline pump is in the fuel tank, relying on gasoline to dissipate and lubricate it, too little oil will not be conducive to the normal operation of the oil pump and reduce its service life.

Because gasoline expands when heated and volatilizes into gasoline vapor in the summer heat, space is needed to accommodate it. If it is too full and there is no room for it, gasoline vapor or even liquid gasoline will enter the canister.

Storage, the carbon canister is full and escapes into the air, which is not only wasteful but also pollutes the environment.

Hello, after the vehicle is refueled, the fuel gauge does not respond, the vehicle can continue to drive, but be sure to mark the relevant mileage. Take a look at how many kilometers the vehicle runs after being filled with fuel before, if it is not marked quietly, this may cause the fuel consumption in the driving to consume the rubber slag, which causes the vehicle to stall in the driving, this is more dangerous If it is a temporary drive, and then take the time to carry out relevant maintenance, there is no problem, this is generally caused by the gasoline float in the gasoline tank, and the fault performance can be solved by replacing the new gasoline float.

When the pointer of the oil gauge does not move, the oil float usually breaks. It is proposed to dock two oil slick lines at the repair shop. If the pointer of the oil gauge reaches the top, it means that the oil float is damaged.

If it still doesn't move, check the line and dashboard. If the pointer does not move when it is just filled with oil, that is, the oil float is pushed to the top of the fuel tank by the buoyancy of the oil, and the pointer connected to the sensor does not move. When a small amount of fuel is consumed, the float is lowered and the pointer moves with the sensor.

Automotive fuel gauges are rich and advanced. It can display the fuel value in the car's fuel tank in real time, telling the owner exactly how much fuel the car has consumed and how much storage is left in the tank. Based on the fuel gauge, the owner will also make a judgment about whether they need to refuel or how many miles they can drive.

The fuel gauge is equivalent to a warning light for the life of the car. A fuel gauge is an indicator that shows the amount of fuel on the engine, either by a pointer or by a number. Therefore, at present, automobile fuel gauges are mainly divided into digital fuel gauges and pointer fuel gauges.

Most digital fuel gauges come with a light-emitting diode display for easy viewing. The fuel gauge has six functions, each of which is indispensable, otherwise it will be difficult for the car owner to drive. The owner can decide whether to refuel or not based on the remaining fuel in the tank shown by the fuel gauge.

If refueling is required, the fuel gauge also shows exactly how much is refueled each time. The fuel gauge not only acts as a scale gauge, but also shows the fuel consumption per kilometer of the car more advanced and accurately, as well as whether it is fuel-efficient. The fuel meter will also remind the owner of the car's remaining fuel mileage.

If the owner does not refuel in time, once the oil storage level is lower than a certain value, the fuel level alarm function will appear on the car fuel meter. In addition, the car fuel gauge can even display the car's odometer, which can store three months of real-time measurement data for data management.

This is normal. Some cars' gas meters don't respond within a few minutes. Refueling is something that many car owners often do. When refueling, they need to choose a large gas station with good oil. Motorists should not go to some small gas stations with bad oil quality for the sake of cheapness.

If you often use some low-quality gasoline, it will lead to more carbon deposits in the car engine, which is harmful to the engine.

The higher the label, the higher the octane number of gasoline, and the higher the octane number, the better the anti-knock performance of gasoline. If high-quality gasoline is added, the fuel consumption of the car will be reduced a little, and the power of the engine will also be increased.

If a round comic is added with less than the specified grade of gasoline, the engine may detonate.

Detonation is an abnormal combustion phenomenon in an engine. When the piston is in the compression stroke, the piston runs upwards. At this point, the piston is compressing the combustible mixture, and the pressure and temperature of the combustible mixture rises.

If the gasoline has poor anti-knock properties, the combustible mixture will burn before the spark plug ignites, which is called knocking.

The combustible gas mixture pushes the piston down, and the piston runs upwards, which damages the engine and causes the engine to drop in power.

Some high-performance cars require 95 gasoline for their engines.
