What to Do When the Fuel System is Running Lean?
1 Answers
Solutions for a lean fuel system: A lean fuel condition occurs when the engine's oxygen sensor detects incomplete combustion of gasoline, indicating too much air and too little fuel. It is recommended to immediately find the nearest repair facility for further inspection. Continued driving may result in sluggish acceleration, increased fuel consumption, and in more severe cases, engine stalling. Causes of a lean fuel system include insufficient fuel pressure, faulty oxygen sensor, malfunctioning mass air flow sensor, intake system leaks, or clogged fuel injectors. The fuel system is responsible for fuel filling and transportation, ensuring that fuel reaches the engine smoothly to power it, while also collecting fuel vapors and filtering them before releasing them into the atmosphere. When the engine is running, the ECU detects the conditions for opening the purge valve, which then opens, allowing fuel vapors to be drawn into the intake manifold by vacuum and burned in the engine.
