Dorman® 645-500 - Oval Mass Air Flow Sensor Connector

A mass air flow sensor is one of the most important components of your vehicle's fuel-injection system. It measures the mass of the air flowing into the combustion chamber and then sends that information to the engine control unit (ECU), which regulates the amount of fuel that must be injected to the cylinders. The mass air flow sensor is critical for proper engine performance, that is why when the sensor fails, it can cause various engine problems such as poor fuel economy, stalling, and a Check Engine light illuminated on the dash. If you are looking for a quality MAF sensor, Dorman offers you the product that is a direct replacement for the factory part but costs less.

With this product, there is no need to replace the entire mass air flow assembly when only the sensor failed, thus saving money, time, and labor. Made from 100% new, high-quality materials, the MAF sensor effectively resists damage from high underhood temperatures, environmental factors, engine vibration, and usual wear and tear. Dorman MAF sensors are engineered for superior function and durability. They feature fiberglass and epoxy laminated circuit boards instead of fragile ceramic boards, wire bonding instead of soldering for consistent connections, platinum wires to resist high temperatures, and silicone potting gel to resist moisture and vibration. Moreover, the part is bench, on-vehicle, and lifecycle tested for long-lasting performance. The mass air flow sensor comes with a torx bit for ease of installation.
