There is a lot of debate on whether petrol can be used to clean the MAF sensor in an engine. Some people believe that it is safe to use petrol as a cleaner, while others are wary of the dangers involved. It is important to weigh up the risks and benefits before making any decisions about using petrol as a cleaning agent for the MAF sensor. Before we go into today’s topic, let us give a briefing about what a MAF is and some of its usefulness.
An internal combustion engine with fuel injection uses a mass (air) flow sensor (MAF) to measure the mass flow rate of air entering the engine.
The engine control unit (ECU) needs the air mass information to balance and deliver the appropriate fuel mass to the engine. The density of air varies with pressure and temperature. For detecting the amount of intake air in each cylinder in automotive applications, mass flow sensors are preferable to volumetric flow sensors since air density fluctuates with ambient temperature, altitude, and the use of forced induction.
Can we use petrol to clean MAF sensor?
Yes, you can use petrol to clean the MAF sensor. However, there are many cleaning solutions available in the market which can be used to clean your car’s MAF sensor and improve its working condition of it.
Using petrol for cleaning can damage the MAF sensor unit, but using a brush or a cotton swab and washing it with water is a better option.
It is advised that if the airbag sensor needs to be cleaned, that it should be done using a non-toxic, environmentally friendly, and reliable method.

What are some of its pros and cons?
In the end, it is important to weigh the pros and cons of using petrol to clean the airbag sensor before making a decision.
Petrol is a non-staining, non-toxic, and environmentally friendly substance that is known to break down organic pollutants. However, using petrol to clean the airbag sensor has some risks associated with it. Firstly, the fuel can be mistaken for the airbag and lead to its deployment. Secondly, using petrol to clean the airbag sensor can damage the sensor itself.
How should petrol be used to clean the MAF sensor?
Here is the step-by-step process.
1. Open Your Engine Cover & See the MAF Sensor
2. Cleaning Method: Remove the MAF Sensor from its location & wipe it clean with a dry cloth
3. Place a few drops of petrol on to each ECU pin
4. Replace the MAF sensor
5. Turn on & Drive
What are some signs to show that your Mass Airflow Sensor is dirty?
- Black Exhaust – The black exhaust from too much fuel is one indication that your car’s MAF is failing. If the MAF is not communicating accurate measurements to the engine management module, too much fuel may end up in the combustion chamber. The catalytic converter may potentially become clogged by the extra fuel.
- Difficulty accelerating – As we just mentioned above, if the air and fuel ratio in the combustion chamber is off, it will cause problems with acceleration. The mass airflow sensor could be at fault for this.
The top auto shop in Stanwood, Washington, is Advanced Automotive. Make a time to visit us so that we can check your car and make sure the mass airflow sensor is operating as it should.
- Hesitation – When you push the accelerator or while you are driving, an air and fuel imbalance can also cause your car to jerk or surge. There is too much air in the combustion chamber, as indicated by the hesitation. Surging indicates an excessive gas level.
Can I use WD40 contact cleaner on mass air flow sensor?
The WD-40 Specialist Contact Cleaner is a fantastic option for cleaning your MAF sensor even if it isn’t specifically marketed as a MAF sensor cleaner spray. For cleaning delicate electrical components, a specialist contact cleaner was created. Plastics are also safe because it leaves no residue.
Can you use carb cleaner to clean a mass air flow sensor?
Carburetor cleaning shouldn’t be used to clean the mass air flow sensor. Carb cleaner leaves an oily residue that is bad for the MAF sensor’s electronics. Use the mass airflow sensor cleaner that is intended for that purpose, or cautiously remove the electronics from the casing and clean them separately.
How long does MAF take to dry after cleaning?
Let your mass airflow sensor sit for at least 20 minutes after cleaning it with the cleanser or rubbing alcohol. Before reinstalling the sensor in your car, it must be thoroughly dry to avoid damage.
