The barometric sensor plays an important role in the smooth running and better performance of your car. For that, the sensor needs to be operational and should not show signs of failure, such as power inefficiency, emission test failure, and excessive fuel consumption. For more details, go through the given slideshow on the various signs of barometric sensor failure in a car.

2. There are several
important
components in your
car which play a
crucial role in the
smooth running and
better performance of
your car.

3. Besides, the mechanical
parts, which help in the
running of the car there
are many sensors that
play an equally vital
role in the overall
functioning of all the
components of your car.

4. 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.

5. As it is a very
important sensor, you
must know the signs
of its failure so that
you can immediately
take remedial
measures.

6. Power
inefficiency

7. The power
inefficiency is one of
the common
symptoms you will
experience when the
barometric sensor
malfunctions.

8. 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.

9. Besides that, due to
the increase in the
refueling frequency,
you will note that the
car's engine cannot be
trusted and is not
working efficiently as it
used to be.

10. If you decrease the
amount of fuel that gets
transmitted to the
engine, then this would
lead to the increase in
temperature in the
combustion chamber.

11. Emission
test failure

12. One of the best way to
test that whether your
barometer is
functioning or not is to
subject your car to an
emission test.

13. This is because a bad
barometric sensor leads
to an increase in the
volume of carbon
monoxide and
hydrocarbon emission.

14. Furthermore, the
exhaust from the
tailpipe of your car will
indicate the bad
condition of the engine
which is very
concerning.

15. Whenever your car
undergoes an emission test
and a high level of carbon
monoxide and
hydrocarbon is detected in
the emission test, then
you should immediately fix
your barometer sensor.

16. Excessive fuel
consumption

17. A malfunctioning
barometric sensor will
provide wrong
measurements of the high
intake pressure and this
can lead to many
problems in your car.

18. This reading is processed
by the computer as a
form of necessity to an
increase the amount of
fuel injected into the
engine and it leads to
increase in the fuel
consumption by the car.

19. If you ever notice that
there is an increase in the
frequency of going to the
filling station, then you
should inspect the
barometer sensor.

20. Moreover, the illumination
of the check engine light
of your car can also
indicate the
malfunctioning of the
barometric sensor.
