oil pressure sensor reading high
Reasons for high oil pressure: First, the oil viscosity is too low; Second, the filter screen of engine oil filter collector or the filter element of engine oil filter is blocked; Third, the spring force of the pressure limiting valve and the oil return valve is weakened or broken, or the joint surface of the valve is not tightly sealed, resulting in oil leakage and pressure relief; Fourth, the clearance of main bearing or connecting rod bearing is too large; Fifth, the oil pump did not work well.
The oil pressure sensor is usually installed in the main oil passage. If the oil pressure gauge and oil pressure sensor are normal, but the indicated pressure of the oil pressure gauge is too low, the possible causes of the failure can be analyzed according to the composition and oil circuit of the lubrication system. If the oil circuit is divided into front and rear parts according to the oil flow direction and the oil pressure sensor as the boundary, the causes of low oil pressure can be divided into two aspects: one is that the oil circuit in front of the oil pressure sensor is blocked (such as the filter is blocked) or the oil supply is insufficient (such as insufficient oil); Second, the oil drain in the oil circuit behind the oil pressure sensor is too fast (such as excessive crankshaft bearing clearance). The high ops of the oil pressure sensor means that the oil pressure is too high, which may indicate that there is a blockage in the engine lubricating oil passage, affecting the oil flow rate and flow.
If the oil pressure is too high, it is likely that there is a blockage in the engine lubricating oil passage, which affects the oil flow rate and flow. The most direct consequence of blocked oil passages is that the mechanical parts behind the blocked points lose lubrication and suffer severe wear. At the same time, the engine oil is also responsible for the internal heat dissipation of the engine. Therefore, when the oil passage is blocked, the heat dissipation effect of the engine will become worse. In addition, if the pressure of the lubricating system is too high, it is easy to cause the surrounding oil seals to be unable to withstand the pressure and leak. Ops is the visual parking system of the car, commonly known as the parking aid system, which is the function expansion of the parking radar. (1) The working principle of the visual parking system is to analyze, process and calculate the ultrasonic signal transmitted from the obstacle received by the ultrasonic sensor of the parking radar. (2) The color of the visual parking system represents the distance between the obstacle and the rear of the car, the green line represents the large distance between the obstacle and the rear of the car, the yellow line represents the distance between the obstacle and the rear of the car 60 cm, the red line represents the distance between the obstacle and the rear of the car 30 cm, and the closer the red line is, the closer the distance is. The accessories included in ops include radar probe, related harness and module supporting OPS.
