For optimal combustion and peak performance, the cylinders in your engine must receive air and fuel in the proper ratio for all operating conditions. The Mass Air Flow (MAF) sensor measures the amount of air entering the engine and signals this information to the Powertrain Control Module (PCM). The PCM uses this information, along with information from other sensors, to control fuel injector on-time and achieve the correct air/fuel mixture.

A faulty MAF sensor may be indicated by hesitation under acceleration, stalling, and an air/fuel mixture that is too rich or too lean. Incorrect air/fuel ratio can be caused by a dirty or contaminated hot wire, which cannot signal air flow accurately. Dirt can also affect the door on a VAF meter, causing it to stick. If the MAF sensor is defective, a Diagnostic Trouble Code (DTC) may be set in the ECM/PCM and the instrument panel CHECK ENGINE light may illuminate. If the air intake system is compromised at any point between the VAF or MAF sensor and combustion chambers, air unaccounted for by the sensor could enter the engine. This would create a lean condition because there would not be enough fuel to mix at the proper ratio with the additional air. When diagnosing a VAF Sensor or MAF sensor, the air intake system should be thoroughly checked for air and vacuum leaks.

No matter what vehicle you’re working on or the type of VAF sensor or MAF sensor problems you’re having, we have the replacement components to restore proper performance, fuel economy and emissions compliance. We offer components that are manufactured to original equipment specifications, so when repairs are completed you can count on the performance and emission system operation your vehicle was designed to deliver. In addition to the components described above, we also offer MAF sensor relays, connectors, gaskets, and adapters, air charge temperature sensors, air charge temperature sensor connectors, and more.

MAF sensors come from the factory calibrated to measure a certain range of air flow, and to work with particular flow rate fuel injectors. This calibration is flexible enough to allow the addition of performance accessories like a performance air intake system, so you can realize the air flow, power and performance gains from this popular add-on without having to change the MAF sensor. However, when air flow is significantly increased, with a larger throttle body and aftermarket intake manifold and cylinder heads, and/or high flow fuel injectors, the factory MAF sensor may not be able to handle the additional flow.

Our performance MAF sensors are essential for highly modified fuel injected engines, but one can also help you realize even greater gains from a cold air intake system. Each application has been dyno tested by our manufacturers to ensure accurate air/fuel ratios for all operating conditions so you get a proven increase in power. In addition to performance MAF sensors, we also offer sensor mounts and adapter kits. If you’re building a custom intake or swapping a modern engine into an older vehicle, the mounts enable sensor attachment, and the adapter kits are an easy way to install a high-flow air filter to the MAF sensor.
