The amount of electronically controlled components in modern cars is considerable and all of them are crucial in keeping your car running in top shape. Unfortunately, these electronic components can cease to function properly over time. This applies to the mass air fuel (MAF) sensor, which functions by ensuring the engine gets the right amount of fuel. While it might not stop working entirely, it could show some signs that it is on the way out, and to help you identify those signs our Westbury Toyota experts have written up a short, thorough guide.
The MAF ensures that the air going into the engine intake is always the correct amount. This is critical as it accounts for how much fuel is needed to maintain the proper ratio for air-fuel (AFR). The ideal AFR is supposed to be 14.7:1, which means that for every 1 pound (lb.) of fuel, there is 14.7 lbs. of air. However, in real world situations, the AFR will vary. When you are driving on cruise control, for example, the AFR could be 22:1, while acceleration could require an AFR of 12:1.
When the MAF sensor starts to malfunction, it will impact the engine control module (ECM), which ultimately results in an inability to correctly calculate fuel injection. When this happens, it will likely lead to issues with your vehicle.
There are several indicators that the MAF sensor may be failing, and some could be misconstrued as other vehicular issues. In order to be able to identify potential problems with the MAF sensor, it will be useful to become familiar with all the signs.
