The crankshaft position sensor is a sensor that monitors the rotational speed and position of the crankshaft. It sends data to the ECU to make necessary adjustments when any kind of malfunction occurs. Bad wiring harness or loose wiring can cause the signal of the crankshaft to be cut off while AUDI A4’s engine is in operational mode. You will notice acceleration issues, reduced gas mileage, rough idling- once after the CPS becomes faulty. Replacement is the most effective solution I guess. Still, prior to replacing the sensor, you should consult a reputable AUDI mechanic and run some tests – for getting a confirmation that the faulty source is the CPS.

1. SIGNS OF A FAILING CRANKSHAFT POSITION
SENSOR IN AN AUDI A4

2. Audi A4 has emerged as a
key player in the niche of
midsize sedan due to its
unique and attractive
features.

3. Onboard computer of
Audi A4 uses data from
various sensors including
crankshaft position
sensors.

4. Such a key sensor
monitors the position and
rotational speed of the
crankshaft of an engine.

5. Any kinds of errors in the
data provided by the
crankshaft position sensor
adversely influence the
performance of an Audi
A4.

6. So, signs of a failing
crankshaft position sensor
or CPS in an Audi A4
should never be
overlooked.

7. Mechanical or electrical
errors associated with the
CPS of an Audi A4 needs
immediate attention.

8. BAD CRANKSHAFT
POSITION SENSOR
IN AN AUDI A4

9. The engine control unit
uses the data provided by
the CPS to regulate the
performance of the engine
of an Audi A4.

10. However, a bad CPS fails
to provide right data
which could adversely
affect the performance of
an engine.

11. Even the engine of an Audi
A4 could even vibrate
heavily.

12. The ECU monitors the
performance of an engine.
CHECK ENGINE
LIGHT

13. However, if it detects any
kinds of errors in the data
provided by the CPS, then
it would turn on the check
engine light.

14. The appearance of such a
crucial warning sign
should not be overlooked
as it could have disastrous
consequences.

15. Any kind of error in any
kind of sensor used in an
Audi A4 could adversely
influence its performance.
ENGINE MISFIRES
AND STALL

16. The crankshaft position
sensor is one of the most
important sensors.

17. Onboard computer of an
Audi A4 relies on the CPS
to regulate the air to fuel
mixture inside the
combustion chamber of an
engine.

18. An engine with a faulty
CPS could misfire or stall
in the middle of nowhere.

19. ENDNOTE

20. Different types of sensors
used in an Audi A4 need
special care.

21. Root causes behind the
failure of the crankshaft
position sensor in an Audi
should be repaired
immediately.
