Lexus RX350 Mass Air Flow Sensor

The Lexus RX350 Mass Air Flow Sensor constantly measures the air rushing into the intake and allows the powertrain computer to mix fuel just right for good acceleration and clean emissions. Two main styles have emerged in the history of the Lexus RX350, the spring-loaded Vane Meter and the Hot Wire, both of which report airflow data to the ECU differently, the former by pivoting a flap connected to a potentiometer and the latter by heating a wire and monitoring the change in current as the air cools the wire. Both Lexus RX350 versions rely on the Mass Air Flow Sensor staying clean for accuracy. Recent Lexus RX350 editions use a hot wire Mass Air Flow Sensor that has faster signal response. Hot Wire units provide freer breathing and fewer moving parts but are prone to dust or oil coating the wire and throwing off the readings, whereas the Vane Meter may stick if the door gets clogged with grime. Whichever style your Lexus uses, a dirty Mass Air Flow Sensor can induce hesitation, stalling, or a glowing check engine lamp since the mixture is too rich or too lean. Routine cleaning of the Mass Air Flow Sensor ensures crisp readings.

Should you need to purchase new auto parts for your vehicle, we strongly suggest you consider the genuine Lexus RX350 Mass Air Flow Sensor available on LexusPartsNow.com. Our OEM Lexus RX350 Mass Air Flow Sensor come with the reassurance of the manufacturer's warranty, a hassle-free return policy, and speedy delivery service, all at affordable prices online.
