The engine may be idle inappropriately, or in some cases, it might not idle at all. However, the PCM is unable to control the quantity of fuel that it sends to the engine. The defective MAF sensor will not send any information regarding airflow to a PCM. The Buick mass airflow sensor symptoms include trouble turning the vehicle, engine hiccups, lean or rich idling, and more. If people prefer to continue driving, then there might be some severe damage to the engine that will be caused and force you to run in the lean air-to-fuel situation. The car owners can still drive it, but it will be less effective as engine hiccups will occur along with multiple more symptoms. This is one of the most affordable and easier options to opt for instead of getting the engine replacement of your car or truck. How do you know if you have a bad mass airflow sensor? The faulty MAF sensor will not prevent the vehicle from running. So, don’t ignore the MAF sensor get it cleaned often, get it to repair if it is necessary.

The engine replacement cost is about $75,000, so it will be recommended that drivers listen to their MAF sensor before breaking the banks.

The following services are commonly performed with a MAF sensor replacement: Hesitation (when you press the gas pedal, the car pauses before accelerating).

Check your vehicle owner’s manual for its recommended maintenance schedule to see exactly how often you should do this.Ĭommon Symptoms That You Need to Replace the Mass Air Flow Sensor However, you should be sure to replace your air filter frequently to ensure that the air passing through your MAF sensor is clean and free of debris that could clog this.

The MAF sensor is durable and has no moving parts, so it does not require regular replacement. Replacing the mass air flow sensor sooner rather than later will avoid these potentially more serious and expensive problems. Ignoring a misfire could result in ignition failure, catalytic converter damage, and unsafe or dangerous conditions while operating the vehicle. If you continue to drive with a bad MAF, it could cause your engine to misfire. You may also get a P0174 code, which is the same problem on a second cylinder bank if your engine has one.

A P0171 code is common, which means there is too much air in the fuel/air mixture. The first thing you may notice is your engine running a little bit rough, or perhaps not having as much power as you expect. What Happens If You Don’t Replace the MAF Sensor? It may also be possible to clean your mass air flow sensor instead of replacing it, but it takes the same amount of time to remove and replace it, so your mechanic will likely just replace it to be sure it’s fixed. Once the mechanic has the part, it shouldn’t take them more than an hour of work to replace it, so your car should be in and out of the shop on the same day. This gives the ECM inaccurate information and causes an incorrect fuel/air mixture. Sometimes this sensor can get clogged with debris or fail entirely. This enables the ECM (the computer that runs the engine) to calculate and add the proper amount of fuel. The mass air flow sensor (MAF) measures how much air goes into your engine. Your engine requires a precise mixture of fuel and air in order to run at maximum power and efficiency.

Also, even if cleaning the sensor doesn’t solve your problem, now you’ll know how to find it, remove it, and replace it yourself. For the minimal cost, it’s well worth trying to clean it before you replace it. But sometimes the sensor is just dirty, and you can fix it yourself with just a $10 can of cleaner. Upon diagnosing a mass air flow sensor problem, a mechanic will typically replace it to make sure the problem is fixed properly the first time. However, you can save even more money by troubleshooting the problem yourself.
