An oil pressure alarm is a small or large thing, it could just be a false alarm from a sensor, or it could be a damaged part that leads to insufficient lubrication and increased engine wear. Generally, if there is an alarm, repair and solve the problem as soon as possible to prevent the increase of problems. We all love the thrill of off-road and enjoy the freedom of pursuit, but it's always a worry when the car alarm comes unexpectedly on the road. Here are the possible causes of the oil pressure alarm, we can make appropriate reference to measure the actual status of the car.
1 The oil pressure indicator light is on and the oil gauge indicator shows low pressure or the instrument display fluctuates greatly, which may be due to the wear of the oil pump and the filter is too dirty. The oil level is low. The air in the oil circuit and the pressure sensor are faulty. 2. In addition, when the engine temperature is too high, it is easy to dilute the oil, resulting in a large loss of oil pressure from the matching gap, and the oil pressure is insufficient to light the alarm; 3. The internal joint parts of the engine due to excessive wear lead to excessive clearance, oil pressure increases, due to the oil gap leads to insufficient seal, which will affect the oil leakage, thus affecting the pressure when the oil pump wear is too large and the gap is too large, it will cause the oil pump does not produce oil or the oil pressure is insufficient; 4 Improper oil selection: If the wrong or improper brand selection, the engine will run due to the oil viscosity is too low and increase the leakage, thereby reducing the oil pressure 5 oil pressure control valve is damaged, so that the oil return valve is damaged, the oil return valve is significantly increased, and the oil pressure of the main oil passage is also decreased;
