The main purpose of the MAF sensor in your Mini Cooper is to measure the amount of air flowing into the engine intake or calculate the amount of fuel to add for achieving the correct mixture of air or fuel in the combustion chamber. If the mass airflow sensor of the Mini is failed, then you will notice the signs defined in the following slides.

1. Symptoms of A Bad Mini
Cooper Mass Air Flow
Sensor in Mill Valley

2. Modern cars have
many sensors for
calculating the correct
amount of air and
fuel.

3. Among different
sensors, the MAF sensor
measures the air mass
flowing into the engine
intake.

4. Moreover, it measures
how much fuel to add
to achieve the correct
air-fuel ratio.

5. If you have a bad MAF
sensor, the ECM cannot
calculate fuel injection
correctly.

6. The following points define the signs of
bad mass airflow sensor in Mini Cooper.

7. Rough Idling

8. Smooth idle is difficult
to achieve without the
proper amount of fuel
in the car.

9. If the MAF sensor has
issues, the engine runs
roughly, especially while
idling.

10. Black Exhaust Smoke

11. In some cases, the
ECM runs so richly
that black smoke
comes out of the
exhaust.

12. Ignoring the issues for
longer can also overload
the catalytic converter.

13. Hard Starting

14. For smooth starting,
the engine may
require more fuel than
idling in Mini.

15. If the MAF sensor is
failed, the ECM does not
command enough fuel
injection to start the
engine.

16. Illuminated Check Engine
Light

17. Performance and
circuit diagnostic
trouble codes may
refer directly to the
MAF sensor.

18. Subsequently, fuel trim
and misfire codes can
also be linked to the
MAF sensor.

19. Hesitation or surging

20. During acceleration,
you might notice
hesitation or sudden
abnormal power.

21. When it happens, you
have to consult a
professional mechanic
to diagnose the MAF
sensor.

22. Conclusion

23. When the MAF sensor
of the Mini is failed,
you have to diagnose
the problem ASAP.

24. Bring your car to a
reputed mechanic for
replacing the MAF
sensor immediately.
