Product Description


Air Mass Meters play a vital role maintaining fuel economy. Faulty Air Mass Meters cause the ECU to default to a “safe map” which generally means your car is going to run poorly due to the excess fuel being funneled through your Volvo’s injection system.

The Air Mass Meter depends on a few significant parts to ensure a longer operating life span. Volvo’s use a thermostat in the air filter box that controls a “hot/cold flapper valve” allowing hot air to flow through the intake to speed up emissions, especially on colder mornings. If the air box thermostat fails, the flapper valve in air box generally fails in the open position, allowing the pre-heat hose off the exhaust manifold, routing hot air through the intake system past the air mass meter. Electrical components don’t like excessive heat. The constant heat running past the Air Mass Meter will eventually cause the circuit board to crack, leaving the soldering board deteriorated and not able to function. IPD has many solutions in replacing and maintaining your Volvos Air Mass Meter.

Please note: This MAF sensor is an updated version that is different from the original hot platinum wire style.  It is  a similar design to later style sensors (i.e. LH 3.1) with an air intake temperature thermistor and a heating resistor.  While it may not look exactly like the original, it is a direct replacement that will function the same or better than the original. That being said, for reasons that have not yet been determined, we have seen a very small number of cars in the application range that won't run with this updated design.  

Potential Product Fitment Issues

Most of these models are equipped with a thermostat controlled air flap in the air filter housing. This system is designed to decrease the engine warm up time (for emissions purposes) but if the thermostat fails, it constantly diverts hot air from the exhaust manifold/downpipe through the air mass meter and will overheat the MAF sensor electronics.

We highly recommend you replace the air filter thermostat at the same time as the MAF (air mass) sensor!

About Genuine Volvo

Everything IPD supplies under the "Genuine Volvo" designation are the factory original Volvo parts. These are the same parts that Volvo used to manufacture your vehicles on the assembly line. All Volvo supplied Genuine Volvo parts are made to specifications by Volvo and under their strict quality control guidelines. Our customers should expect the same high-quality when purchasing Genuine Volvo products which in the past were exclusively available as dealer only items. Volvo relies on other high-quality OEM manufactures such as Lemforder, Behr, Sachs, Bosch, Valeo, Siemens, VDO, Corteco, and many more to maintain its dedication to quality and safety.

IPD is the exclusive North American distributor for Genuine Classic Volvo parts outside of the Volvo Dealership network. We are proud of our Volvo heritage dating back to 1963, a reputation that is unmatched by others in the industry.

Many may not know this but Volvo in Latin roughly translates to "to roll".  The company was founded back in 1927 by Assar Gabrielsson and Gustaf Larsson as a spin-off from ball-bearing manufacturer SKF.  While the Volvo logo looks like the biology symbol for male, it's really the Swedish symbol for Iron. With a nod to its heritage in alloys, Volvo chose a logo that depicted a ring bisecting at one o’clock. Today Volvo is known around the world as one of the most iconic brands known for safety, longevity, and its enthusiast following.

IPD has been proudly serving the Volvo community since 1963. We are motivated to be the very best destination for your Volvo needs. Our customer and vehicle first approach means that your experience is our first priority. We have truly hassle-free returns, an in depth Volvo blog, and provide DIY Volvo guides and videos for many of our products.
