Before we proceed, it should be known that Mass Air Flow (MAF) sensors are responsible for the detection of any leak in your exhaust system. With any leak, the MAF sensor will alert the system while setting off a light that peeps up from your dashboard.
How to Trick Your MAF Sensor
Your MAF sensor has a similar tube with a special design, same size and shape also. While the MAF sensor is made of plastic. This lookalike tube is made of metal and offers close functionality.
Step 1: With this tube, place it on the surface of your ignition source to have it heat up and offer your MAF sensor a similar temperature to the fuel-air mixture propelling from the car’s tailpipe.
Step 2: Get a gas of any type except filthy gasoline for cars. Since the MAF sensor admits heat quickly, with your gas choice, it provides the same outcome as to how hot it gets and how much mixture of fuel and air it produces.
Step 3: Observe the release of heat from the open flame as it would trick the MAF sensor to read higher than expected. This scenario has its risk to your car’s engine.
Beware that tricking the MAF sensor is like a bandage. It’s better replaced with a new sensor than tricking a faulty one.
What Is Mass Air Flow Sensor? Why Is It Necessary In The Car?
The MAF sensor helps mitigates blow in your engine. A blow can occur in your engine when there is too much fuel but less air in the combustion chamber which will cause uncontrolled blasts within the cylinder.
The impact of this can have your piston and valves damaged and simultaneously cause your car to malfunction severely. MAF has been seen in many cars and trucks and its value can’t be overemphasized.
Its function is basically to measure the amount of air as it moves through the engine and informs the car of how much fuel to deliver. If the MAF sensor malfunctions, your engine will as well malfunction. For instance, if the MAF senses you’re receiving more air when you’re not, it will cause the motor to deliver more fuel than required.
This can cause your engine to blow. Since the function of this sensor is just to measure the amount of air entering your engine, it can be tricked into sensing that more air is passing in than it is. And this makes your engine run with a higher octane than it supposes.
By tricking the MAF sensor to believe you’re receiving more air, you can mitigate your car’s engine from a blow. For instance, should your engine need 87 octanes to mitigate blow, and you’re using less than that, your engine will likely blow.
What Happens If You Have A Bad Mass Air Flow Sensor?
The MAF sensor is a vital aspect of your engine as it measures the airflow coming into the engine and sends a piece of information to your car’s system to adjust functionality for optimal performance.
The MAF sensor is important because it lets your engine function at its peak and operates with lower emissions. The cause of the MAF sensor failure is usually a result of contamination. Though there are other reasons why it can fail.
If your MAF sensor should fail, you will receive a code indication of such occurrence and a decline in your car’s performance. Let’s assume your car did not malfunction at an early stage, you will notice a drastic reduction in fuel economy. Replacing failed MAF sensor is necessary as it impacts your car’s engine performance.
The code will appear on your dash and illuminate the check engine light when the MAF fails. When you notice such an indication, take your car to the mechanic to determine the level of failure the MAF sensor gets to and for subsequent replacement.
Disadvantages of Having a Bad MAF Sensor?
There are three basic disadvantages of a failed MAF sensor. And each defect in the MAF harms the engine.
Firstly, the oxidized sensor will read lower than it should. When this happens, it seems you have more power propelling from the engine than measured by the instrument cluster. This causes the wear and tear of the engine parts due to excess usage.
Secondly, a Bad MAF sensor reduces the engine’s functionality. This indicates a lack of enough fuel received for proper combustion, some of the fuel will be expelled unburned from the exhaust. this causes fuel wastage and decreased engine performance and increased detrimental emissions.
Thirdly, a bad MAF sensor will force the car to run rich. This is when your car burns too much fuel and most of the fuel is expelled unburnt through the exhaust. it causes the same thing as decreased engine performance and harmful emissions.
When Should You Bypass MAF Sensor?
Every car has its MAF sensor to measure the amount of air propelling into the engine for optimal fuel consumption and power. When you don’t often drive your car or the plugged-in chargers aren’t transmitting power as required, it will cause the MAF to freeze and can’t pass any air reading again.
Due to this, there will be a poor or faulty reading of miles per gallon, which eventually leads to high fuel consumption and malfunctioning of the engine. Tricking the MAF sensor is the most utilized means to fix this challenge for decades.
If you seem the fault is more than just a tick on the MAF sensor, consider taking it to the mechanic for diagnosis and possible repair or replacement of the MAF sensor.
The knowledge of how to trick your MAF sensor is vital to all drivers besides resetting the MAF sensor before you will consider taking it to the mechanic.
If the MAF sensor should fail, the readings and miles per gallon shown on the dash will be erroneous and causes the engine to malfunction. As a result, you will be wasting money on fuels and trying to improve your car performance without fixing the main problem which is the MAF sensor.
Therefore, pay attention to what we have detailed here today to enable you to trick your mass air flow sensor.
