What is the reason why the oil light is on when the neutral gear is on, and the throttle indicator l

The approximate reasons are as follows:

The oil volume of the engine oil is insufficient, so that the oil volume of the oil pump is reduced or the oil cannot be pumped due to air intake, resulting in the oil pressure dropping;

If the engine temperature is too high, it is easy to thin the oil, and a large amount of oil pressure will be lost from the mating gap.

When the oil pump parts are damaged or there is too much gap due to wear, assembly and other problems, it will cause the failure of the oil pump to produce oil or insufficient oil.

When the oil light is on when you put it in neutral gear, you have to check whether the oil on the oil pump is good, you can open the oil cap where the oil is added, and see if there is organic oil splashing inside the engine through this small opening.

If there is, it means that the impact is not large, it is because the new oil is too thin and not thick enough, when the vehicle travels a certain distance or the engine runs for a period of time when the oil is hot, due to the oil is too thin, the oil sensor collects the lack of oil pressure.

When the oil light is on when idling, it does not light up after acceleration, it is likely that the oil pump is faulty, the oil pump is not oiled well, or the oil pump filter is too dirty.

The pressure of the oil is not enough, so it will cause the oil light to turn on when in neutral, and add a little throttle indicator light to turn off, this oil light will not affect the normal use of the vehicle, and will not cause damage to the engine.

The oil volume of the engine oil is insufficient, so that the oil volume of the oil pump is reduced or the oil cannot be pumped due to air intake, resulting in the oil pressure dropping;

When the engine is idling, the oil light sometimes flashes slightly, or sometimes it lights up temporarily after emergency braking, and turns off when you press the throttle lightly, indicating that the system is normal. Do not worry. That's how automakers design it.

Is it possible when the car is hot, but not when it is cold? Yes, just like me, I changed the oil sensor and the oil with a viscosity of 40, and the problem was solved, and the oil viscosity became lower during the hot drive, which caused this.

If the car is old, the oil filter is too dirty and affects the oil absorption, it is recommended to disassemble the oil pan to clean the lubrication system. In the future, to ensure the quality of oil products, there are too many parallel cargo oils on the market now.

It is suitable to choose winter and summer engine oil according to the season; Pay attention to the engine temperature should not be too high, the reduction of viscosity will affect the oil pressure; The engine idle speed should not be too low.

I changed the oil, and the oil light was still on, probably because: 1If the oil is too thick, it is recommended to change the oil to a lighter one.

2.Oil induction plug false alarm, replace oil induction plug 3Blocked oil passages lead to slow oil application.

It is recommended to go to the repair shop to check and repair the yacco engine oil.

Cause: The inside of the engine lubrication system is too dirty, and there is gum, which leads to oil blockage.

Plugs and filters are clogged, so that the system does not establish pressure properly.

The crankshaft bearings, connecting rod bearings, and camshaft bearings are worn out too much, resulting in the lubrication system failing to maintain the lubrication pressure and causing the oil lamp to light up.

Engine oil, that is, engine lubricant, English name: engine oil. The density is about to lubricate and reduce friction, assist cooling and cooling, seal leakage, rust and corrosion, shock absorption and cushioning for the engine.

The engine is the heart of the car, and there are many metal surfaces in the engine that rub against each other, and these parts move fast, the environment is poor, and the operating temperature can reach 400°C to 600°C.

Find out the cause of the lack of engine oil:

Excessive oil consumption, or excessive wear and tear of related parts leads to string oil, and the oil is discharged after burning through the two cakes and lotus cakes, and the exhaust can be judged by observing the exhaust color, and the exhaust of gasoline vehicles has blue smoke in general. It can also be judged by checking the cylinder pressure.

Oil leakage, observe the leakage after the vehicle is jacked and dispose of it.

What kind of car are you, there are several possibilities for the common oil indicator light to be on, one is that the oil indicator line is short-circuited or the pressure of the oil pump is not enough, go to the repair shop to find a maintenance master to check the cause of the fault for specific reasons such as oil induction plug failure.

There are two possibilities, one is that the oil has been used for a long time and has become viscous, and the other is that the oil has burned some when it is used.

Get it repaired right away! It should be caused by insufficient oil pressure! The consequences are severe.

The oil duct is blocked, or there is a problem with the sensor.

If the engine oil lamp is lit, it may be caused by insufficient oil pressure, and the common fault points of insufficient oil pressure are, damaged oil pump, damaged oil sensor, and so on.

See if the oil pan screws are loose and if the oil pan is damaged.

Hello, in this case, you should first test whether the oil pressure is normal, and replace the pressure sensor if the pressure is normal. Abnormal pressure is usually a problem with the oil pump or small watts.

When the oil pressure alarm, you must first determine whether it is a true alarm or a false alarm.

1. True alarm: that is, the oil pressure is indeed lower than the design requirements.

Reasons: 1. Lack of engine oil.

2. The lubricating oil circuit is blocked.

3. The oil filter of the oil pan is blocked.

4. The oil filter is unqualified or the model is wrong.

5. There is a problem with the oil pump.

6. Turbocharger pressure relief.

6. There is a problem with the selection of oil viscosity, the viscosity of the choice is too low, which does not meet the design requirements of the engine manufacturer, or water enters the oil (caused by the cylinder gasket).

Solution: Use the oil intuition meter to directly measure the actual pressure of the oil, and then gradually eliminate the solution according to the above reasons!

2. False alarm: that is, there is no problem with the actual oil pressure, but the alarm is called!

Reasons: 1. There is a problem with the oil induction plug itself.

2. There is a problem with the line connecting the induction plug.

If there is a problem with the oil of the car, the vehicle will be affected, and some car owners find that the oil light of their car is on, and the accelerator is off, so what is the reason why the oil light is off if the oil light is not on the accelerator?

1. It may be that the oil inside the engine is too thin, that is, the viscosity of the oil is too low, so that the car will not reach the specified oil pressure when it is idling, the oil lamp will be on, and the oil with higher viscosity needs to be replaced.

2. Hail can be cautious because the bearing of the crankshaft is worn, the gap of the bearing will become larger, and the oil will leak from between the bearings when the car is idling, and the pressure of the oil will be insufficient, and the bearing needs to be replaced in the 4S shop.

3. It may be that there is a problem with the oil pump, and the car cannot reach enough oil pressure in the case of low speed, and the oil pump needs to be replaced.

4. It may also be the fault of the oil pressure sensor source, the oil itself is not a problem, it is the sensor failure that causes the data to transmit the filial piety manuscript to be incorrect, and the oil pressure sensor needs to be replaced.

Don't run, in case the engine cylinder slip tile caused by low oil pressure will be overhauled, check the idle motor when the neutral slide is turned off, and take a little throttle when the neutral coast is running, and clean the throttle and idle motor if the engine is not turned off.

The car oil lamp is lit in neutral, it is not lit when refueling, can it be turned on again Hello, I am helping you sort out the answer to the question, please wait a while Hello, this situation should not be opened, so as not to lose a lot due to small losses, you can take a look at the lack of oil, look at the oil dipstick, the oil lamp is the most dangerous, if the control is not good, it may damage the engine, resulting in unnecessary maintenance costs, it is best to enter the store to check whether it is a lack of oil, or a fault caused by low oil pressure, and the problem of the oil pressure sensor! Don't open it.

There is no shortage of oil, run high-speed refueling for a period of time, turn off the engine when the oil pressure is low, and the engine cylinder slip will be overhauled if the oil pressure is low, check the idle motor, and take a little throttle when the neutral slide, if you don't turn off the engine, clean the throttle and idle motor.

The reason why the oil lamp is on but there is no shortage of oil: 1. The pressure limiting valve is blocked or improperly adjusted, in order to prevent the oil pressure of the lubrication system from being too high and increasing the power consumption of the engine, resulting in oil leakage at the sealing connection in the oil circuit, etc., a pressure limiting valve is set on the main oil channel or oil pump. Its function is to limit the oil pressure of the lubrication system, so that it does not exceed the specified value, the failure of the pressure limiting valve will lead to the abnormal oil pressure of the oil of the machine, so that the oil lamp is on; 2. The engine temperature is too high, if the engine cooling system has too much scale, poor heat dissipation, long-term overload operation or too late fuel supply time of the fuel injection pump, etc., the engine will overheat, accelerate the aging of the oil, deteriorate, and thin, leak from the gaps of each mating, reduce the pressure, and turn on the oil fault lamp; 3. When the oil filter is blocked and cannot flow, the bypass valve located on its base is opened, and the oil directly enters the main oil channel without filtration.

If the opening pressure of the bypass valve is set too high or too low, the pressure of the oil pump will rise or fall, which will also cause the alarm light to come on.
