How Could you Find the Faulty Speed Sensor of your Car

1
How could you find the FAULTY SPEED SENSOR of
your CAR
2
There are two types of speed sensors are
available in the car such as engine speed sensor
and transmission speed sensor.
3
The engine speed sensor detects the revolutions
per minute of the engine's crankshaft spinning
and the transmission speed sensor detects the
fastest traveling of your car.
4
In the dashboard, the tachometer represent the
engine speed, as well as the speedometer,
represent the transmission speed.
5
The engine control unit receives the information
from the sensor and takes appropriate action to
perform all the functions of the engine and
transmission.
6
If you find that the sensors of your car are
damaged, then the following points will help you
to determine the faulty sensor in your car.
7
Damaged cruise control
8
If the cruise control mechanism of your car is
working properly, then the transmission speed
sensor of your car run functionally.
9
When the engine control unit unable to receive
the information about the speed of the car, then
the cruise control unable to maintain the same
speed.
10
If the sensor fails to deliver the accurate data
to the onboard computer of the car, the
powertrain control module sends an error code to
the car.
11
If you notice that when you press the cruise
control control button it does not engage, then
it may be the reason of faulty speed sensor.
12
Check engine light
13
When you find that the check engine light of
your car is illuminated, this is a clear
indication of a faulty speed sensor of your car.
14
The ECU depends on the speed information of the
engine's crankshaft. When it does not receive the
information, it can automatically illuminate the
check engine light.
15
It also indicates the increases of tailpipe
emissions that can surpass the acceptable limits
for environmental contaminants from cars.
16
When you notice that the check engine light comes
on, you should contact a mechanic to scan the
error codes.
17
Malfunctioned speedometer
18
When you find that your car's speedometer stops
functioning all of a sudden, then it will clearly
indicate that the speed sensor has some defects.
19
The malfunctioning of the speed sensor indicates
that the speedometer of your car will not have
the ability to read the speed of the car.
20
This issues is very risky for your car because
you will drive your car without aware about the
exact speed of the car that has registered.
21
The malfunctioning of the speedometer due to the
faulty speed sensor can cause unnecessary and
unavoidable accidents.
22
Improper shifting
23
Without the valid speed signal from the sensor,
the power control unit not able to control the
shifting of gears within the transmission.
24
It may cause a problem with the sensor and impact
the shift timing as well as extending the time
interval between the transmission shifts.
25
When you find that the transmission shifts are
hard, then it can damage the internal components
of the car.
26
If you notice that the transmission of your car
is shifting harshly or roughly, then you need to
contact a mechanic as soon as possible.
27
Conclusion
28
If you find any of the above symptoms in your
car, then take your car to a professional
mechanic to diagnose it and to identify the
faults.
