What does engine FML mean?

[LaneMarie]

Engine fault FML-17 indicates insufficient fuel supply, which means the throttle is dirty and there is carbon buildup that needs cleaning. Situations of insufficient engine fuel supply: When the engine operates at low speed with a small throttle opening, the oil pump does not draw much oil, and the main oil passage can still establish a certain pressure, so the oil pressure remains normal. However, when the throttle is opened wider for high-speed operation, the oil pump's oil intake will significantly decrease due to excessive resistance from the oil strainer, leading to insufficient oil supply in the main oil passage and a drop in the oil pressure gauge reading. The oil strainer should be cleaned or the oil replaced. If the engine oil level is insufficient, the solution is: This will reduce the oil pump's output or prevent oil from being pumped due to air intake, causing a drop in oil pressure. The crankshaft and bearings, as well as the cylinder liners and pistons, will experience increased wear due to poor lubrication.
