How to Deal with a Lean Fuel Mixture Fault?
1 Answers
Methods for handling a lean fuel mixture fault: You should immediately find the nearest repair facility for further inspection. Continuing to drive may result in loss of acceleration, increased fuel consumption, and in more severe cases, engine stalling. Additional information: 1. Function of the fuel system: The fuel system is responsible for fuel filling and transportation, ensuring that fuel reaches the engine smoothly to provide power for engine operation. It also collects fuel vapors and filters them before releasing them into the atmosphere. When the engine is running, if the ECU detects that the conditions for opening the carbon canister purge valve are met, the valve opens, allowing fuel vapors to enter the engine under the vacuum pressure of the intake manifold to participate in combustion. 2. Causes of a lean fuel system: Insufficient fuel pressure, faulty oxygen sensor, faulty air flow meter, intake system leaks, clogged fuel injectors.
