Genuine Saturn LS Mass Air Flow Sensor

The Saturn LS Mass Air Flow Sensor makes sure that the engine is getting the correct air charge to mix with fuel in the right way for smooth power. By continuously measuring the incoming air and relaying this information to the powertrain control module, this Mass Air Flow Sensor allows the computer to adjust the pulse width of the injectors to match every move of the throttle and the change in weather. Early Saturn sedans applied a Vane Air Flow meter style Mass Air Flow Sensor with a spring-loaded flap connected to a potentiometer that responded to airflow, could stick if dirty, and choke out performance, causing lean or rich mixtures. Later LS models applied the Hot Wire Mass Air Flow Sensor, which suspends a heated wire in the stream and monitors current changes caused by air cooling it, providing faster, less restricted readings. Compared to the older flap meter, the Hot Wire unit on trims is better able to adjust to altitude and temperature changes, but oil or dust on the wire can still mess things up, actuate the check engine light, and make acceleration stumble. When any air leak sneaks in after the Mass Air Flow Sensor, the PCM reads less air than the engine swallows, runs lean, and the 3.0 liter Saturn motor feels weak or stalls, so drivers check hoses and clean the sensor for balance. Any LS breathing is kept right by attention.
