MAF sensor
The MAF sensor is a key component in any car’s engine management system. It stands for “mass air flow” and is responsible for measuring the amount of air flowing into the engine. This information is then used by the engine control unit (ECU) to adjust the fuel injection and ignition timing accordingly.
A MAF sensor typically consists of a hot wire or hot film element, through which the incoming air passes. As the air passes over the heated element, its temperature changes. This change in temperature is then used to calculate the mass of air flowing into the engine.
MAF sensors are important because they allow the engine to run more efficiently. If too much or too little air is being drawn into the engine, it can run lean (not enough fuel) or rich (too much fuel). This can cause a number of problems, including reduced power, decreased fuel economy, and increased emissions.
For this reason, it’s important to keep your MAF sensor clean. Over time, it can become clogged with dirt and debris, which can interfere with its ability to accurately measure the amount of air flowing into the engine. If you suspect your MAF sensor is dirty, you should have it cleaned by a professional.
