Tips To Maintain The MAF Sensor Of Your Porsche

by schearerswpadmin June 29, 2018

Although the mass airflow (MAF) sensor is intended to last for the entire life of the car, your Porsche may encounter a damaged MAF sensor over time. This sensor is a small component of your Porsche, but it plays a critical role. Not all mass airflow sensor parts are the same, so it’s important to get the help of a professional Porsche specialist to ensure any repairs or maintenance tasks are performed properly. In this article, we’ll go over the importance of the MAF sensor, how to detect a failing MAF sensor, and what you can do to adequately maintain the sensor.

What Function Does The MAF Sensor Serve In Your Porsche?
The MAF sensor in a Porsche lends significantly to its overall function and performance. This important little part is responsible for the huge task of determining the right fuel-to-air ratio that the engine needs in order to combust and ignite efficiently and reliably. Your Porsche’s MAF sensor reports data to the car’s ECU about the air that flows through the engine, and then the ECU determines how much fuel is appropriate for the specific needs of the engine. When the MAF sensor begins to fail, malfunction, or becomes damaged, it causes evident problems with your car’s functionality. If the problem persists, it could lead to further engine problems and damages that can add up over time.

Symptoms Of A Struggling MAF Sensor
Your Porsche’s performance surprisingly relies heavily on the proper function of the MAF sensor. It’s important to keep an eye on how your Porsche performs on a day-to-day basis, and to document any changes in its functioning. As we previously mentioned, the longer the problem persists the more damages your car can encounter. It’s best to bring your Porsche to a specialist as soon as possible if you notice any of the following symptoms in your own car:

Idling Roughly
A rough idle can indicate any number of things are going wrong with your Porsche; however, a rough idle in combination with any of these other symptoms points heavily toward MAF sensor failure. Notice how your car idles at red lights or while you’re parked.

When the MAF sensor begins failing, it cannot communicate the engine’s combustion needs (i.e. dispersed fuel amount) appropriately. This often leads to engine stalling, usually right after ignition. If this occurs, your check-engine light may come on, which can be helpful for diagnostic processes.

Issues Starting the Car
If you’ve experienced difficulty starting your Porsche, it’s probably best to have it towed to the nearest, trustworthy Porsche repair shop in town. Starting issues aren’t inherent to MAF sensor failure, but if the engine cannot get the fuel it needs, you may go through a painful, tedious process of starting and stalling.

Decrease in Power
Porsche’s are known for the get-up-and-go spirit—they don’t waste any time upon acceleration. If your MAF sensor isn’t working right, you’ll notice a significant impediment upon acceleration. This is a concerning sign of MAF sensor failure, but it can also be related to other engine or transmission issues.

Lowered Fuel Efficiency
Porsche’s aren’t particularly well liked for their fuel economy; however, MAF sensor damage or issues can cause lowered fuel efficiency, which is a red flag for automotive specialists. It’s important to report lowered fuel efficiency along with any of the other mentioned symptoms so that your Porsche specialist can rule-out other causes of fuel issues.

How To Prevent MAF Sensor Failure In Your Porsche
Although the MAF sensor is intended to last for the life of your car, regular maintenance can reduce the amount of strain put on the sensor over time. Here are a few things you can do to prevent MAF sensor failure:

Remove and clean the sensor
Inspect and maintain the PCV valve
By keeping up with these basic tasks, your Porsche can avoid the frustrating symptoms associated with MAF sensor issues.

what people say about us

Excellent & timely service – keep up the great job!! =D

Excellent service. Work done on time as promised.

Just got back from having a turn signal bulb replaced… For $133… Bulb is available for $7.98 online, but the intensive training required to unscrew the old bulb and screw in the new one must have been very costly indeed. Was looking for a new place to go for service on my GTI. Got a postcard saying “you don’t have to go to the dealer” As horrible as the dealer is, I very certainly would have been much better off. Oh, and they charged me $80.00 for the bulb! I said that’s some real markup on that and they told me it was 65% markup as they bought it for $25.00… Unbelievable.

You always take good care of my daughters car. Fast reliable and honest service.

Very Professional and Through in their Work. They have my Trust in their recommendations.

Always professional. I’m a 7 year customer. I’ve had several vehicles serviced here and I’ve never had to worry that the work wasn’t done properly.

You are always very helpful to me. Had my car ready on time , the time I said needed it. No loaner cars available but so good of Rayanne and Christie to get me back and forth. Thank you so much.

Thank you for polite and professional service!

Work nicely done at a reasonable price – made recommendations for (necessary!) additional work I hadn’t considered. Left one wire disconnected, but that was promptly and properly corrected. Thanks!

Service at Schearers is always meticulous and professional. The work for which I brought my car in was done well, and an inspection of potential future problems was also undertaken, enabling me to plan for future maintenance to keep my car running smoothly. I am satisfied, as always, with the quality of work and the professionalism of everyone I encountered at Schearers.

Excellent service as usual. Work was done in a timely fashion at a reasonable price. I really like the loaner car arrangement. Mike was very nice to schedule service on the same day and get the necessary parts quickly. Samantha provided a coupon from the internet. Thanks

Friendly service and fair pricing.

Very personable owner/ family. Made us feel comfortable. Explained everything that was necessary for our car upkeep. Prices better than other foreign car dealerships. Car was completed in a timely manner. Will recommend to friends. Thank you

I wish I had found them earlier! Great company and very talented group of mechanics, specializing in German cars. They do excellent work and you’ll save a lot of money over the dealer.

Polite, helpful staff and professional service always!

Great experience! From the first call I made and spoke with Kristy to Mike walking me through and explaining what he was going to do. Mike also did an evaluation and let me know what to expect regarding services my car will need in the future. Exceptional customer service from beginning to end, including Samantha taking my payment. I told Mike, I am a customer for life! Well done Scherrers!! Jim Rowlands

The headlight lens cleaning was great. Thanks for suggesting.

Tom and the team deliver again! There is a reason we come back for our fleet of cars, excellent, trustworthy service with a personal touch. Keep up the great work.

Great Professional service!! I originaly contacted Schearer’s to get an estimate for my bmw M3 oil pan replacement because the threads were stripped.

Shearer’s yet again provided exceptional service! I am always informed of any maintenance requirements, reasons for, and associated costs before any actions are taken. They offered flexibility for returning home while the work was done in terms of a loaner car or ride. Everyone with whom I spoke was knowledgeable, courteous, and supportive. I highly recommend Shearer’s to service your car!

Always very nice and accommodating being that I live in Vermont. Will definitely have them maintain my sons car for the next 2 years while he attends school in PA.

Incredible service at a great price. I totally trust the Schearer’s Team!

Excellent service, easy to schedule an appointment, and love the “loaner” option!
