Throttle position sensor


Throttle body showing "wide open throttle" sensor on the right


A throttle position sensor (TPS) is a sensor used to monitor the position of the throttle in an internal combustion engine. The sensor is usually located on the butterfly spindle so that it can directly monitor the position of the throttle valve butterfly.
The sensor is usually a potentiometer, and therefore provides a variable resistance dependent upon the position of the valve (and hence throttle position).
The sensor signal is used by the engine control unit (ECU) as an input to its control system. The ignition timing and fuel injection timing (and potentially other parameters) are altered depending upon the position of the throttle, and also depending on the rate of change of that position. For example, in fuel injected engines, in order to avoid stalling, extra fuel may be injected if the throttle is opened rapidly (mimicking the accelerator pump of carburetor systems).
More advanced forms of the sensor are also used, for example an extra closed throttle position sensor (CTPS) may be employed to indicate that the throttle is completely closed.
Some ECUs also control the throttle position and if that is done the position sensor is utilised in a feedback loop to enable that control.
Related to the TPS are accelerator pedal sensors, which often include a wide open throttle (WOT) sensor. The accelerator pedal sensors are used in "drive by wire" systems, and the most common use of a wide open throttle sensor is for the kickdown function on automatic transmissions.
Modern day sensors are Non Contact type, wherein a Magnet and a Hall Sensor is used. In the potentiometric type sensors, two metal parts are in contact with each other, while the butterfly valve is turned from zero to WOT, there is a change in the resistance and this change in resistance is given as the input to the ECU.
Non Contact type TPS work on the principle of Hall Effect, wherein the magnet is the dynamic part which mounted on the butterfly valve spindle and the hall sensor is mounted with the body and is stationary. When the magnet mounted on the spindle which is rotated from zero to WOT, there is a change in the magnetic field for the hall sensor. The change in the magnetic field is sensed by the hall sensor and the hall voltage generated is given as the input to the ECU. Normally a two pole magnet is used for TPS and the magnet may be of Diametrical type or Ring type or segment type, however the magnet is defined to have a certain magnetic field.

above info clears the ,,xtp feature of bs-26 carb of gs-150r

Wow good info thank you sir
Please do mention the source

source is wikipedia, correct if i am wrong
AFAIK TPS controls ECO n PWR modes, n in GOD mode tps is turned off.
XTP (Xtra Torquey Performance) has nothing to do with TPS

yes.. Will take the delivery today..

Cheers..

congrats bro
enjoy your ride

Engine Rough / smooth

hi all,

my GS engine become smooth automatically for the last 300+ km

milage on highway is 69KM/Lr!!!!!!... - first time in my bike
on normal ride 64 !!!!! (tested 3 times continuously on PWR mode)
vibration start at 85 - 90 km speed

my GS completed 1 yr & 9400+km

my previous average milage is 52 to 55 on normal city ride
& maximum milage is only 60...
Vibration start from 55-60 km on 'rough mode'

too good figures man!!!!!!!
these figures are comparable to any 100cc!!
how??? what you have done???
any effects on power delivery??

anyways
That are some real +ve signs....

other riders who have crossed 9-10k write down your figures too..

hi sameer,
Tune the carburator for better performance
calculate milage after 3rd or 4th service

A quick update...completed 9000km on odo...mileage i am getting is 52-56kmpl..
Today changed the oil from castrol active 20w40 to castrol power one 15w40.

The oil changing procedure which i followed is :
1) opened the oil bolt...and completely drained the old oil.
2) filled the engine with 700ml petrol.
3) turned the engine on for 1min..so that petrol will clean the engine thoroughly.
4) drained the petrol completely.
5) Finally fed the engine with castrol power one.

After doing this..i found gear shifting to be butter smooth. acceleration in very much increased,the bike sounds as if new.

But the only problem i had is the tappet noise. but will surely do the tappet settings tomorow...

so how was the petrol when you drained it???

Guys dont try that procedure its for old model 100cc bikes

In other word petrol is a fuel / solvent where engine oil is to cool the engine.

+1 Never Try this Procedure This is used my Local mechs in Hero Honda But never to be tried in GS. If you want to Flush the engine and save your 60K then just use a Engine Oil Pour it in and Run the Engine for 5 Minutes and Flush it out. This is the safest way to Do it. I will not recommend the petrol Flushing to Anyone. This is Not recommended even by suzuki mech whom i interact very well.He Told sir '200 ka engine oil dalwa key Flush karwa lo why risk the 60k item.'
