Lexus GS300 Replacement Air Mass Sensor Information


The air mass sensor or MAF (mass air flow sensor) on your Lexus GS300 is continually on the job when the engine is operating, sending vital information to the engine control module related to the mass or density of the air being used to make up the air/fuel mixture being delivered to the engine cylinders for combustion. Air mass is a continually changing aspect the fuel delivery system, sensitive to many factors including air temperature and pressure. Because the computer is always striving to provide a precise air/fuel ratio of 14.7 to 1, changing air mass must be countered with a constantly changing amount of fuel. A faulty air mass sensor sending inaccurate info to the computer will affect both performance and economy and must be replaced.
