2. Combustion engines with fuel
injection systems use a
manifold absolute pressure
sensor or MAP sensor.

3. Function of a MAP sensor
is similar to that of a
mass airflow sensor or
MAF sensor. But, some
engine uses both types of
sensors for better
outcomes.

4. A MAP sensor monitors the
manifold pressure or airflow
and sends those data to the
engine control unit or ECU.

5. The ECU uses this data to
monitor the engine’s mass
air flow rate and to regulate
the fuel injection system
accordingly.

6. Malfunction in such an
important sensor might
negatively affect the power
output of an engine.

7. MAP sensor needs special
attention and signs which
show that the MAP sensor
has defects that should not
be neglected.

10. The ECU uses outputs of a
MAP sensor to regulate the
air to fuel ratio inside the
engine.

11. Errors in the data provided
by the MAP sensor might
affect the air to fuel ratio
inside the combustion
chamber.

12. Disproportionate amount of
air to fuel ratio might
negatively affect the power
put of an engine.

13. So, signs of a rich or lean
air-fuel mixture inside a
combustion engine should not
be neglected.

15. Data provided by a faulty
MAP sensor to the ECU
might be responsible for
poor fuel economy.

16. Errors in the data provided
to the ECU induces the fuel
injection system to inject
more fuel into the
combustion chamber.

17. So, a sudden rise in the
rate of fuel consumption by
the engine should not be
ignored.

19. Defects in any type of
sensors in a car including
the MAP sensor would
trigger the check engine
light to illuminate.

20. So, illumination of this
warning light should never be
ignored.

22. The fact is that injection
of excess amount of fuel
into the combustion
chamber might produce a
huge amount of unburned
hydrocarbons, oxides of
nitrogen, and carbon
monoxide.

23. So, the root cause behind
the generation of such a
huge amount of
environmental pollutants
should be identified and
repaired in time.

25. A MAP sensor plays a vital
role in the process of the
internal combustion.

26. Mechanical or electrical
faults in this sensor might
adversely affect the power
output of an engine.

27. Timely efforts should be
made to fix the problems
associated with such an
important sensor.
