What to do if the oil pressure light is on? This question was asked by many. It can be assumed that any driver at least once lights 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 one hundred percent sure that something is faulty in the car. And if the bulb you never lit, then consider that you are fortunate enough not to encounter the subsequent problems that this signal portends.
So, what does the illuminated red light on the oil pressure indicator portend? There are many reasons for this. The main rule, if the oil pressure light is on, be sure to stop and think about what kind of malfunction your car suffered, because further movement can lead to even more deplorable results. It is best to call a tow truck or friends who tow you to the garage or the nearest car service. And already in a calm environment to identify a malfunction. Finding a breakdown in a car is much more difficult than eliminating it later.
The most common reason that the oil pressure lamp lights up is because the oil level in the sump is low. In order to avoid this, you need to periodically conduct your own inspection. Do not be lazy, get the dipstick and look at the oil level in your engine. After all, it does not take much time, but you will be calm in motion. Maybe, of course, the engine can leak, so always look closely at your parking spots, oil spots will form there, informing you that something is dripping from the engine. Having found this, take appropriate measures. In the car, in fact, the oil level gradually decreases due to the constant operation of the engine and the movement of the vehicle. Some engines even before the light comes on, let you know that the oil is running out. Most often, they periodically begin to stall. In such situations, you can stand for a couple of minutes to let the oil glass in the pan and start up again. But be aware that after a short time the engine will stall again. Therefore, from changing to changing oil, you need to add it at least once.
If the oil does not leak anywhere, and the engine has a positive oil level, then perhaps the sensor itself, which is responsible for the oil pressure, or its wiring, does not work for you. It is after the sensor is triggered that the indicator lamp lights up , notifying us of a malfunction. With a shortage of oil, the sensor closes the bulb, and when the pressure rises to a certain level, it opens it. If the sensor is faulty, the indicator light will be on steadily.
The next reason that the oil pressure light is on is a pressure relief valve malfunction . If the system has low oil pressure, then the valve must be closed, if it is, of course, working. If the valve freezes or sticks, then this factor also indicates that there is no pressure in the engine. For these reasons, the light is on.
The oil filter may be to blame for the causes of oil pressure. After the engine stops, oil should remain in the filter to simplify its next start-up. If it, perhaps, flows from it into a pallet, then most likely it is not original. It is advisable to replace oil filters at the same time as oil.
If all of these nuances are checked and the oil pressure light is still on, then there may be all the reasons in the oil pump. First of all, check the mesh, which is responsible for protecting the engine from the penetration of large particles along with oil. If you somehow poured a poor-quality product into the engine, then, of course, this grid clogs very quickly, which leads to a decrease in pressure in the engine, and, accordingly, the oil pressure lamp lights up.
