What should I do if the oil pressure lamp is on?

What should I do if the oil pressure lamp is on? Many asked this question. We can assume that any driver at least once lit up the oil pressure lamp on the dashboard. As a rule, it burns at idle, or after starting the engine. If you find this, you can be sure one hundred percent that something is wrong in the car. And if the light bulb you have never caught fire, then consider that you are so lucky not to face the subsequent problems that this signal signals.

So, what can the red light bulb on the oil pressure indicator foreshadow? There are many reasons for this. The main rule, if the oil pressure lamp is on, be sure to stop and think about what kind of malfunction has befallen your car. Further movement may lead to even more deplorable results. It is best to call an evacuator or friends who will tow you to the garage or the nearest car service. And already in a quiet environment to identify a malfunction. Finding a breakdown in a car is more difficult than removing it later.

The most common reason that the oil pressure lamp lights up is the low level of the oil in the pan. In order to avoid this, you need to periodically conduct your own inspection. Do not be lazy, remove the dipstick and look at the oil level in your engine. It does not take much time, but you will be calm in movement. Maybe, of course, the engine leaks, so always look closely at your parking spots, there will be oil marks, informing you that something is dripping from the engine. Having discovered this, take appropriate measures. In the car, as a matter of fact, the oil level gradually decreases due to the constant work of the engine and the movement of the vehicle. Some engines even before the light bulb, let you know that the oil is already running out. Most often, they periodically begin to stupor. In such situations, you can stand a couple of minutes to oil the glass in the pan, and start again. But be aware that in a short time the engine will again stall. Therefore, from replacement to changing the oil, you need at least once to pour it.

If the oil is not leaking anywhere, and the engine has a positive oil level, then perhaps the oil pressure sensor or its wiring is not working. It is after the sensor is triggered that a warning light comes on to alert us of a malfunction. When there is a shortage of oil, the sensor closes the light bulb, and when the pressure rises to a certain level, it opens it. If the sensor is defective, the indicator light will remain lit.

The next reason that the oil pressure lamp is on is the failure of the pressure relief valve. If the system has low oil pressure, then the valve should be closed, if it is, of course, normal. If the valve hangs or sticks, this factor also indicates that there is no pressure in the engine. For these reasons, and a light is on.

In the causes of oil pressure, the oil filter may be to blame . After stopping the engine, the oil must remain in the filter to simplify its next start-up. If it can drain out of it, then, most likely, it is not original. It is desirable to replace oil filters simultaneously with oil.

If all these nuances listed are checked, and the oil pressure lamp is still on, then maybe all the reasons in the oil pump. First check the mesh, which is responsible for protecting the engine from the penetration of large particles with oil. If you somehow poured a poor-quality product into the engine, then, of course, this grid very quickly clogs, which leads to a decrease in pressure in the engine, and, accordingly, the oil pressure lamp lights up.
