Some cars house the MAF sensor inside the air filter box, so open it up and move the box aside to find the MAF sensor. Every car’s MAF sensor placement is slightly different. If you’re still unsure where your sensor is located, check your car’s manual. Or, search online for “mass air flow sensor” with your car’s make and model.
Do not use anything besides MAF cleaner to clean your sensor. This cleaner is specifically designed to clean its delicate wire or plate. Using brushes, cloths, other car part cleaners, or rubbing alcohol can damage the sensor. [7] X Research source If the wire or plate still has gunk covering it or doesn’t look bright and shiny, spray it with more cleaner until it’s sparkling.
It might be tempting, but don’t dry your MAF sensor off with a cloth. The sensor is super delicate and wiping it can damage its parts.
If you have a car stalling issue or a lit check engine light, cleaning the MAF sensor can often solve the issue. If these problems persist, your sensor might just be old or faulty. To replace it, search for the MAF sensor that’s compatible with your car or check your car’s manual. Simply unplug the connector, take out the sensor, and pop in your new one. [10] X Research source
