Most car owners are unaware about just how important their fuel and air mixture is to the performance that they enjoy. Without a fully regulated air and fuel system, your car will not be able to run as it is intended to. There are a number of different components on your vehicle that are designed to keep this mixture consistent. The MAP sensor is among the most used and vital components on a car in regards to the air and fuel system. This sensor helps gathers information on the amount of air entering the engine and its temperature. When running your car, you will be helped out greatly by this sensor.

Once the MAP sensor gets the information on the air and its temperature, it will alert the engine computer if there needs to be any changes in the amount of fuel needed. Each of the sensors on your car are supposed to last as long as the car does, but this is not always the case. If your MAP sensor is not working correctly, then it will be hard to keep your car running at peak condition. When signs of trouble start to arise, you will have to take the time to make sure you get the proper repairs done. The time that is put into getting these repairs done will be worth due to the functionality they can restore.

Due to the location of the MAP sensor, it will usually not be checked on a frequent basis. This means that you will not have any previous dealings with this part until it is need of replacement.
