Why Does the Dashboard Fuel Consumption Number Jump Around?
2 Answers
The dashboard fuel consumption number jumps around due to issues with the onboard computer. Here is some relevant information about the car dashboard: 1. Introduction: The car dashboard is a device that reflects the working conditions of various vehicle systems. Common indicators include the fuel indicator, washer fluid indicator, electronic throttle indicator, front and rear fog light indicators, and warning lights. Different cars have different dashboards. However, conventional dashboards in most cars include the speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, and charging gauge. 2. Precautions: Normally, the brightness of the dashboard does not require manual adjustment. It automatically adjusts based on the intensity of the external ambient light.
I also experienced erratic fuel consumption readings on the dashboard when I first got my new car. Turns out it's related to the fuel calculation mode. The instantaneous fuel consumption value updates every 0.5 seconds - it directly shows 30L/100km when you press the accelerator hard, and instantly drops to 2L during braking or downhill driving. Later, I broke the habit of frequent lane changes and tried to maintain a steady speed around 60 km/h on highways, and the fuel consumption display stabilized between 6.8-7.2. If the readings keep fluctuating by more than 2 fuel levels for a long time, remember to check the oxygen sensor. Last time my car had this issue due to carbon buildup on the sensor causing data distortion, and it immediately returned to normal after replacement. Using eco mode during normal driving works particularly well for stabilizing fuel consumption readings, and gentle acceleration makes the numbers less sensitive.
