What s going on with the car self test oil indicator light not on

It is normal for the oil lamp to not turn on, and if it is on, it means that there is a problem with the oil. You put the key in the power-on state, if the self-test does not light up, it means that there is a problem, and the detection is not open. A car battery is a car that is charged by a generator after it is started.

Cars don't use the electrical energy from batteries while driving. A high level of electrical energy is required for ignition. Remember to turn off the lights when you park.

If the car does not drive for a long time, the battery should be disconnected. This is done to the maintenance of the battery.

Adding too much oil will not cause the oil lamp to not light up.

First of all, the oil lamp is the signal given by the oil pressure sensor, which is that after the car starts, the oil pump generates oil pressure to turn off the oil pressure sensor, and at this time, the oil is not lit. So, when you turn on the car key, the oil light is on, starts and turns off.

The lubricating oil is monitored by the oil level sensor or oil pressure sensor to detect the position or pressure of the oil, when the oil level is too low or the oil pressure is too low due to insufficient oil quantity, the oil indicator will be lit, as long as the oil level or oil pressure is higher than the minimum value, the oil indicator will not be lit, that is to say, the oil will not be lit if the oil is added too much.

You didn't change the oil before it was good, there should be no big problem, it may be that the repairman bar oil pressure sensor line was knocked off when changing the filter, go to the repair shop to plug it in. The normal charging of the battery should be ten hours, depending on how much current you use.

The oil light does not come on.

bai, which can only indicate the current machine du

The oil pressure is enough, that is to say, although the amount of oil is lower than the lower limit of the oil dipstick, the oil pressure of the oil pump is enough, and the design has a certain margin! It is advisable to go to the repair shop to explain the situation, write down the location of the oil and the current mileage, and then replenish the oil immediately, keep the evidence, get into the habit of checking the oil level regularly, and find the cause of the high oil consumption.

It is normal for the oil warning light and the power generation indicator to be lit after the engine is not started (on the contrary, it is not normal if it is not lit), this is because the engine is not started, so the oil pump and generator are not working, at this time the generator does not generate electricity, and the oil is not pressurized, so these two indicators are used to remind the driver of the working status of the car.

After the engine starts, the generator and the oil pump start to work, at this time the generator has begun to generate electricity, and the oil pump works to make the oil reach a certain pressure to meet the needs of the engine, so these two alarm lights will go out, which means that the system is running normally.

Some of the self-test oil lamps are on for a while, only a few indicators are on before starting, and they are generally fine when they are turned off after starting. As long as the oil is enough. It should be a problem with the oil line, put the line of the oil induction plug to see if it is bright, if it is bright, it proves that the oil induction plug is broken.

The car oil shortage indicator will not light up, which may be due to the fact that although the oil is less, the oil pressure does not affect the working condition of the engine, so the oil warning light is not on.

When the oil storage in the oil pan is too small, there is air in the oil pump and the pump cannot be oiled, resulting in a drop in oil pressure, then the oil pressure warning light will be on, and the oil needs to be replenished in time.

In general, the higher the viscosity of the oil, the higher the oil pressure. And if the viscosity of the oil is lower, then the oil pressure will also be lower, and the oil pressure warning light will be on. Oil of the appropriate grade should be used, and it is recommended to follow the recommended viscosity in the maintenance manual.

The oil lamp will be on and off for a while, it may be a lack of oil, or it may be that the pressure lamp is broken. If you find that the oil light is flashing or on during normal driving, you must stop immediately to seek rescue.

If your gasoline lamp is on when it starts and goes off after a while, it may be caused by the low pressure of the car just starting, if it is often on and off, you can consider the following problems: 1The amount of oil is insufficient.

2.The engine temperature is too high.

3.The oil filter and suction disc are clogged.

4.The return valve is damaged or malfunctioning.

I think it should be that the oil pressure caused by the engine overheating is not enough, so it will always turn on and not on.

There is a certain failure of the lamp, and the engine also has a certain reason, and the oil is missing, and the oil label is not suitable, so there will be a situation where it is on and off.

1.The oil volume of the engine oil is insufficient, the oil volume of the oil pump is reduced or the pump cannot be oiled due to air intake; 2.If the engine temperature is too high, it is easy to thin the oil and lose a lot of it from the mating gap; 3.

The oil pump parts are damaged, resulting in the oil pump not producing oil or insufficient oil output; 4.The matching gap between the crankshaft and the large and small tiles is improper, and the oil pressure will increase and decrease if it is too tight and too loose; 5.The oil filter and suction disc are clogged. 6.

The return valve is damaged or malfunctioning. 7.Improper selection of engine oil, wrong use or improper selection of grades, the leakage will be increased due to the low viscosity of the engine oil when the engine is running; 8.There is oil leakage and blockage in the oil pipeline.

Engine oil is known as the "blood" of the car, and not only does it play the role of lubrication, but now it has more and more functions. Many oils can also play a role in reducing wear, auxiliary cooling, sealing leakage, rust and corrosion, shock absorption and cushioning. One can imagine how much damage it can cause to the engine if there is a lack of oil.

Oil lamps are important indicators on the dashboard of a car. Because the engine has strict requirements for oil pressure, too high or too low oil pressure will affect the operation of the engine. So using organic oil lamps helps us find the problem as soon as possible. What causes an oil lamp to turn on? How do I inspect and repair?

The most common cause of oil lamps to light is a lack of oil. At this time, the oil volume in the oil pump decreases, and the oil pressure decreases accordingly. In order to confirm whether there is a shortage of oil, we need to measure with an oil dipstick.

First, the vehicle must stand for a while until the oil level is stable, and then place the dipstick vertically to observe the oil level. If we find that the oil level is lower than the standard value, we need to refuel. There is one more point worth noting here.

Because too much oil can also cause the engine to run poorly, so add it slowly and never pour it all in.

If the oil level is normal, but the oil lamp is still on, it may be caused by the low viscosity of the oil, because the pressure value of the oil is directly proportional to the viscosity of the oil, and the oil viscosity decreases, and the oil pressure will naturally decrease. There are many reasons for the low viscosity of engine oil, such as the viscosity of the oil decreases when the fuel is mixed with the engine oil, the viscosity of the oil decreases when the engine temperature is too high, and it may even be that the owner does not pay attention to the type of engine oil when choosing the oil, and the viscosity of the added engine oil is low, so it is necessary to consider whether to change the engine oil according to the actual situation.

Finally, due to the fact that the oil has a certain cleaning function, when the engine produces too much sludge, it will cause the oil to clog, and the engine fault light will also come on at this time. Generally, the reason for this is that the oil has not been changed for a long time, and a large amount of dirt has accumulated inside the oil. On top of that, some car owners are greedy for cheap and can also cause this to happen when adding low-quality oil to their vehicles or mixing other liquids when adding oil.

At this point, we need to change the oil.

In addition, since the oil lamp itself is an electronic component, there may also be problems, such as a short circuit in the instrument panel lamp wire, a malfunction of the oil pressure sensor itself, etc. , which can also cause the oil lamp to light up. At this time, the oil fault lies in the automotive circuit system, and we only need to prescribe the right medicine, repair the relevant parts or circuits, and eliminate the fault.
