How to Clean the MAF on a Lexus


You can save significantly on mechanic bills by doing basic maintenance yourself. Many car owners are aware that replacing your air, oil and fuel filters on a regular basis will help keep your car running smoothly and maintain fuel efficiency. Fewer people are aware of the mass air flow, or MAF, sensor and the part it plays in your car’s fuel economy. This sensor detects the amount of air in the engines intake system and, in conjunction with the electronic control unit, controls the amount of fuel supplied to the engine. A dirty MAF can lead to excess amounts of fuel being used, rough idling, sluggish acceleration and reduced power. Cleaning the mass air flow sensor every two years or 20,000 miles will help prevent this problem.
