fuel gauge level on obd2
Some new gauges support calling out the remaining mileage of the fuel tank, which is common for some new cars. The remaining mileage is automatically calculated based on the average fuel consumption of the last 30km of driving and the remaining fuel in the car. For example, a car The average fuel consumption per unit mileage is 8l/100km, and the remaining fuel in the fuel tank is 40l, so the remaining mileage displayed by the meter is 500 kilometers. Of course, the remaining mileage is dynamically changed and estimated according to your current average fuel consumption.
Detect with obd2
This method is a bit high for the average car owner. There are many testers with obd interfaces on the Internet, some are bluetooth interfaces, and some are directly connected. This tester can directly read the remaining fuel in the trip computer. Relatively speaking, it is more intuitive and accurate.
Arrow on instrument:
There is usually an arrow on the oil gauge, which aims to point to the direction where the oil filler is located on the body. Convenient for refueling and parking. Refueling without power off is easy to lead to wrong metering of the fuel gauge. When we go to refuel, we often require to turn off the engine and turn off the power supply of the car. On the one hand, this is to avoid fire caused by circuit ignition. Another reason is that when the power supply of the whole car is turned on, the change of fuel quantity will not be reflected on the driving computer in real time. At this time, it is easy to lead to inaccurate metering of the pointer of the fuel gauge.
Is there any damage to the oil pump when the oil gauge light is on?
Many people on the Internet say that after the oil gauge light is on, the oil pump cannot pump oil and cannot dissipate heat, which will lead to the damage of the oil pump. This is pure nonsense. Although the automobile gasoline pump is soaked in the fuel, it does not use the shell of the fuel pump to cool, but pumps the fuel from the pipeline to the inside of the pump through axial flow for heat dissipation, that is, as long as the fuel can be pumped, there will be no heat dissipation problem.Usually the first compartment of the fuel gauge is more durable, which is caused by the irregular shape of the fuel tank, which is large at the top and small at the bottom. Generally, the current remaining fuel amount can be roughly estimated by the pointer. If the pointer is in the lower middle or in the red line area, it means that there is no oil and you need to refuel as soon as possible.
