A throttle position sensor is a device that detects the position of the throttle body which is essential for determining how much air will enter the engine. The role of this sensor has made it a key component of the vehicle’s fuel management system. ECU will fail to determine the position of the throttle, when the sensor goes bad. A faulty sensor can be notified by various warning syndromes. Being a motorist, it is your responsibility to be aware of those symptoms so that you can replace the faulty sensor before experiencing a costly hassle due to its failure.

2. Needless to say that, the
internal combustion engine
needs a sufficient amount of air
for the complete combustion of
the fuel.

3. Combustion of one liter of fuel
needs about fourteen liters of
oxygen inside the engine of a
car.

4. Modern car engine uses
different types of sensors to
work efficiently. The primary
job of a throttle position sensor
or TPS is to monitor the
position of the throttle valve.

5. Throttle valve allows the flow
of air into the combustion
chamber of the car.

6. Output provided by TPS to the
engine control unit (ECU)
helps to regulate the injection
of fuel and air into the
combustion chamber of the
engine.

7. Malfunctions in such an
important sensor might have
adverse impacts on the
performance of a car.

10. Any kind of error in any type of
sensors in a car would trigger
the check engine light.

11. Finding the root cause behind
the illumination of check
engine light is a little bit
difficult, but it is really
necessary to detect and fix the
problem in time.

12. The condition of different types
of sensors including TPS
should be inspected
immediately.

14. The ECU uses the inputs
provided by TPS to regulate the
fuel to air ratio inside the
combustion chamber of the
engine.

15. However, a faulty TPS could not
provide the right set of
information required by the
ECU to regulate the fuel to air
ratio.

16. Injection of an insufficient
amount of fuel or air into the
combustion chamber might
adversely affect the power
output of an engine.

17. Efforts should be made to fix
such problems in time.

19. Injection of an excess amount
of air or fuel into the
combustion chamber might
lead to engine misfiring.

20. Errors in the TPS might lead to
engine misfiring.

21. So, early warning signs of a
failed TPS should not be
neglected and efforts should be
made to fix such problems.

23. TPS plays an important role in
the performance of an engine.

24. Any kinds of mechanical or
electrical errors in such an
important sensor might have
disastrous consequences.

25. So, timely action is required to
fix such problems.
