Problems mass air flow sensor symptoms legacy

On mass air flow sensors with a sense wire, this wire can become contaminated with dust particles. Find the mass air flow sensor that fits a SUBARU Legacy. Failure symptoms. Problems with Mass Air Flow. The SUBARU Legacy Mass Air Flow sensor is. Some mechanics will recommend to clean the sensor every time you replace the air filter. Most mass air flow sensors are one piece hermetically sealed units with no moving components. This measurement is used by the engine computer or ECM to calculate proper amount of fuel injected into the cylinders in order to provide optimum combustion and low emissions. This method allows the computer to do an accurate analysis of the air  entering the engine.

This depends on how bad the car is running. These particles can be removed with automotive solvents that are safe for the use on mass air flow sensors. Rough idle, engine hesitation, lack of power and poor fuel economy. Maintenance Tips/Suggestions SUBARU Legacy Mass air flow sensor requires no regular maintenance. They use this as an input signal to the vehicle's main computer.

See all problems of the 2000 Subaru Legacy. Mass Air Flow Sensor problem of the 2000 Subaru Legacy 1 Failure Date: Vehicle stopped during normal driving and there was a lost of power steering and braking. It allows air to enter the engine without the computer knowing about it. Not only can a contaminated mass airflow sensor cause hesitation and stalling, but it can also cause poor fuel economy and performance. On older vehicles that don't have this function a cleaning will be necessary at some point.
