What is Throttle Position sensor and how does it works?

The basic function of the TP sensor is that it tells the reading
Ecm whether the throttle is open ecm reduce the amount of air and fuel to equalize in the engine.

1,location:
The Location of the tp sensor is on the back and front side of the throttle.

2,Works:
Tells the air ratio to the computer when the vehicle is parked or drive.

3,symptoms of A Bad Tp Sensor:
First of all the checking light came on & genrate Few dtc p0122 , p0123, p0124 and p2135.

4,Weak acceleration.
When ecu is not getting data So more amountof air and less amount of petrol
got mixed in the engine.

5,engine Rough Idling:
When the tp sensor is damaged or weak So in the speed of 600 to 900 rpm
the up and down keep happening.

6,Excess Fuel consumption:
Ecu gets wrong signal due to bad throtel sensor,
Because of which the amount of air and fuel in the engine is not equal
and car gives poor black smoke or smells of petrol and the car may take longer starting.

7.Acceleration changes:
Sometimes the car doesn’t take the whole race And sometimes car would race herself than necessary.
