Your mechanic will test the system and determine how bad the mass airflow sensor failure is. This means you need to take your vehicle to your mechanic for diagnosis and repair.

The car will throw a code on the dash and illuminate the check engine light when this happens. It’s essential to replace a faulty mass airflow sensor as soon as possible because this will optimize your engine’s performance. When this happens, you will get a code indicating a mass airflow sensor failure has occurred. But one of the most common failures of this part is that it becomes contaminated, which causes it to fail. The airflow sensor can fail in several ways. Why is this important? Because you want the engine to perform at its best in order to burn fuel and operate with lower emissions efficiently. It measures the amount of air coming into the engine and sends a reading to your car’s computer, which then adjusts the engine accordingly for optimal performance. The Mass Air Flow Sensor is an essential part of your car’s engine.

How To Test Your MAF (Mass Air Flow Sensor) & HOW to Find A Vacuum Leak What Happens If You Have A Bad Mass Air Flow Sensor? This method of tricking the MAF sensor takes advantage of its relatively high sensitivity towards heat.

For example, if your car requires 87 octanes to prevent knock, and you’re using less than 87 octanes, you will be susceptible to knock. This can allow your engine to run with a higher octane than its actual rating.īy tricking the MAF sensor into thinking that you are using more air, you will prevent or alleviate possible knocks in your engine. Since a mass airflow sensor is essentially just a tube that measures the amount of air entering your engine, you can trick it into thinking more air is coming in than it is. For example, if it thinks you’re getting more air when you’re not, it will try to deliver more fuel than needed. If the MAF doesn’t function properly, your engine will not run correctly. It measures the amount of air as it passes through your engine, which lets the car or truck know how much fuel to deliver.

MAF is a standard sensor found in many cars and trucks. This can damage your pistons and valves and eventually lead to serious problems with your car’s performance. Knock results from having too much fuel and not enough air in the combustion chamber, which causes uncontrolled explosions within the cylinder. Using a mass airflow (MAF) sensor properly is necessary to prevent a knock in your engine.

  • However, air mass flow sensors are extremely sensitive to heat.Īs such, a tiny amount of heat from an open flame can trick the sensor into reading higher than it should, which is detrimental to your engine if this happens. The gas used does not matter how hot it is and how much fuel-air mixture it can produce. This tube has the same shape as the airflow sensor and is made of metal, not plastic.īy placing it in front of an ignition source, it will heat up and give the same reading as the fuel-air mixture coming from your car’s tailpipe. If you want to trick a mass airflow sensor, you’ll need a unique tube. How To Trick A Mass Air Flow Sensor? Yes, there are ways to trick the mass airflow sensor. Generally speaking, bypassing is not desirable because it wastes money unnecessarily while at the same time it could lead to severe damage if left unchecked. A single leak will cause the MAF sensor to trigger and set off a light that pokes up from your dashboard. MAF sensors are used on all cars to detect any leak in your exhaust system.
