What does P049600 High Flow in Fuel Tank Exhaust System mean?

[VonPatrick]

P049600 High Flow in the fuel tank exhaust system indicates incorrect high pressure flow in the fuel tank exhaust system, a short circuit in the fuel tank exhaust valve, an open circuit in the fuel tank exhaust system activation, or an electrical fault in the fuel tank exhaust valve circuit. Below are specific details related to fuel consumption: 1. Fuel Consumption: The fuel consumption of large-displacement cars is as high as that of family cars. 2. Comparison: For a fuel consumption of 6 liters per 100 kilometers, on the same route, a 1.6L car like the Octavia consumes 7 liters. Sports cars typically have much heavier throttle usage than street cars, leading to higher fuel consumption. The fuel consumption of liter-class sports cars during rapid acceleration or high-speed driving is comparable to the combined fuel consumption of a 3.0L car. 3. Fuel: Most cars use gasoline, so the energy content of the fuel is the same. The relatively higher fuel consumption of the Octavia comes from high wind resistance, a compact structure that leaves no room for fuel-saving technologies, and a design philosophy that emphasizes high-revving power extraction.
