Signs of Barometric Sensor Failure in Your Car Most car owners are aware of the mechanical parts used in their car and are very apt in maintaining all the important parts of their car like the engine and the transmission. However, apart from the engine and the transmission, there are also other parts in your car that play a crucial role in its smooth running and better performance. Your car is equipped with many sensors that help the vital parts in their efficient functioning. Among all the sensors that help in the smooth running of the car, the barometric sensor plays a critical role in the performance of the car. The barometric sensor works in conjunction with the MAP sensor or Manifold Absolute Pressure sensor for the smooth running of the car. The barometer is used in the car to measure the air density. The barometer sensor works in conjunction with the Manifold Absolute Pressure sensor to ascertain the pressure, density, and other factors. The information collected is then passed on to the car's computer so that it can take correct decisions regarding the airflow and fuel mixture. If the barometer sensor malfunctions, then your car is going to face serious issues. Here in this article, we will discuss the signs of barometric sensor failure.
Inefficiency in power The inefficiency in power is one of the primary signs associated with the malfunctioning of the barometric sensor. If the barometric sensor will always provide a wrong reading on the intake manifold pressure, then the car's engine will decrease the amount of fuel being transferred to the motor. Besides that, due to the increase in the refueling frequency, you will note that the car's engine cannot be trusted and efficient as it used to be. If you decrease the amount of fuel that gets transferred to the engine, then this would lead to an increase in temperature in the combustion chamber and the power output due to the internal combustion process will decrease.
Decrease in the engine performance When the barometric sensor fails to transfer the correct information to the car's computer that is the electronic control unit, it results in the disruption of pressure balance. This leads to the weakening of the engine. You can notice these symptoms whenever you accelerate or slow down your car as the engine will jerk the moment you press the pedal. Furthermore, if you experience rough riding then it is time to inspect your barometric sensor.
Emission failure One of the most commonly reported a sign of barometric sensor failure is the car's inability to pass an emission test. A malfunctioning barometric sensor leads to an increase in the volume of hydrocarbon & carbon monoxide emission. In addition to this, the exhaust from the tailpipe will indicate the bad condition of the engine. Whenever your car undergoes an emission test and a high level of carbon monoxide and hydrocarbon is detected in the emission test, then you must immediately inspect the barometric sensor and take your car to a certified mechanic to fix any faults in the sensor.
Fuel economy gets affected A malfunctioning barometric sensor will provide wrong measurements of the high intake pressure. This reading is processed by the computer as a form of necessity to increase the amount of fuel injected into the engine. This leads to an increase in the fuel consumption of the car. If you ever notice that there is an increase in the frequency of going to the filling station, then you should inspect the barometric sensor.
Illumination of the check engine light Nowadays, most modern cars are coming equipped with many additional features that are helpful in detecting any issues before it takes turn for the worse. One such component in your car is the check engine light which is a warning light &
