Volvo Mass Air Flow Sensor - Genuine Volvo 31459404

Product Information

Mass air flow sensors are tasked with measuring the amount of air entering the engine via the intake. This mass air flow sensor is known as a hot film sensor which will suffer performance deterioration over time. The sensor is designed to be self cleaning. A faulty or non functioning mass air flow sensor will cause a check engine light and in some cases cause a limp mode. The best way to diagnose a faulty mass air flow sensor is to disconnect it and see if engine idle or performance improves.

• Check engine light illumniated with OBD codes related to MAF sensor faults
• Engine has rough idle and/or stalls
• Short term fuel trim is rich at idle or lean under load
• Constantly runs rich or lean

About Genuine Volvo

The original parts used by Volvo to build your car are available as replacement parts under the “Genuine Volvo” brand. Manufactured under the direction of Volvo, expect excellent quality and a premium price since these parts are exclusively available through the Volvo Dealership network.

You may not realize this, but the parts that make up your Volvo are not necessarily manufactured by Volvo. No cause for concern, as Volvo designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Volvo for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Volvo parts box and find an OEM branded part inside, simply with the addition of a Volvo logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
