What is the location and function of the Mass Airflow (MAF) sensor?

The MAF sensor is located on the air filter housing with a platinum hot wire, thermistor and control circuit inside a plastic housing. This sensor makes use of a sensing element (hot-wire) to check the molecular mass (weight) of intake air into the engine. As the throttle opens, more air passes over the hot wire, thereby cooling it down. The function of this MAF sensor circuit is to retain the hot wire at one unaltered preset temperature by managing how current flows through it. As it cools down, PCM augments current through this hot wire in order to maintain its temperature at that particular degree. The voltage signal output from the MAF sensor fluctuates depending on this flow of current. This signal is then converted into digital waveform by PCM that calculates fuel injector pulse width (duration), turns injectors on and off correspondingly. Any trouble in such sensor circuit will activate diagnostic trouble code. Assure key ignition is OFF; remove electrical connector from MAF sensor; take out two screws holding sensor-take off both O-ring plus MAF sensors from housing air filter; fit new O-ring before reinserting them and reverse installation process.

Pontiac Vibe Mass Air Flow Sensor

The Mass Air Flow (MAF) Sensor in the Pontiac Vibe vehicles is very important as it is used in controlling the air supply to the engine. This information is sent to the PCM, the fuel injector timing is then altered in order to regulate the required air-fuel ratio. The Mass Air Flow Sensor can be of two types, the Vane Meter (VAF) and Hot Wire sensors both of which work on different principles to measure airflow. The VAF sensor uses a spring-loaded vane and the Hot Wire sensor uses current changes in a heated wire to measure airflow and is more accurate. Nonetheless, both types can be a subject to contamination which can cause such problems as stalling or incorrect air-fuel mixture. As a result, Mass Air Flow Sensor should be kept in good condition to prevent any problem as any dysfunction will set the check engine light and trouble codes.

Each OEM Pontiac Vibe Mass Air Flow Sensor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
