[TIPS] How to set your TPS

Well I don't know whether the values below will work in other countries version... but let's try

Tools:
- Digital avometer
- Needle

To check your TPS:
1. Turn off your engine and electricity, release TPS wires from the socket.
2. Set digital avo to ohm meter, connect (+) terminal to blue wire and (-) to black-blue wire.
3. Check whether the avo shows value between 3k-7k ohm, if not, it's time to replace your TPS with the new one

To check your TPS linearity:
1. Plug back in TPS wires to its socket. turn on electricity.
2. Set digital avo to dc voltmeter, connect (+) terminal to yellow wire and (-) to black-blue wire.
3. Check whether the avo shows value 5V, if not, it's time to replace your TPS with the new one
4. Set digital avo back to ohm meter, and open throttle smoothly.
5. Check whether the avo shows linear increase value from 0-5k ohm, if not, replace your TPS

To adjust TPS degree:
1. Set idle rpm to 1300-1500 rpm
2. Set digital avo to dc voltmeter, connect (+) to yellow, (-) to black-blue wire
3. Adjust your TPS position by loosen its nut to get avo value between 0.63-0.73V

Bad/broken tps will cause your engine to get bad mileage and bad acceleration. Too low idle rpm will cause engine to sound unpleasant because decompression is still working.

Sorry if there are some bad english :D

Thanks for the tips!!!

also to add AVOMETER is also called MULTIMETER/ MULTITESTER in some countries.
known brands are SANWA japan.

its the device used by electronic repairman which is available on hardware stores/electronic stores.

regarding
1. Set idle rpm to 1300-1500 rpm

how will you know the rpm range?
is the tachometer used by cars can be used on our motorcycle
like brands like Autogauge?

Dunno how accurate is an Autogauge. But I've used the Daytona Digital RPM Meter with (great) success. Pretty accurate. Tap onto yr spark plug lead for reading.

Well hehehe, the easiest way is to turn on the headlight, set your idle rpm until the headlight turn not too bright but not blinking anymore. Also, if you hear to the engine... the decompression stop to work at 1300-1500 rpm, so if you still hear your engine 'knock' (decompression still working), means your idle rpm is too low.

Yes, AVOMETER is also called MULTIMETER

And some Yamaha workshop/garage should have digital rpm... with a holder to sparkplug wire.

hey guys, dose the TPS have an affect on the throtle response? even when the engine is warm, when i rev the throtle it kinda chokes, like it's not getting enough of something, any hints on cause?? goff_d_p1@hotmail.com thanks

ACORDING TO MY MACHANIC IT'S TOO EARLY FOR FOR RE-JETTING MY CARBS. ONLY 1,820Klm. I WENT ON A TWO HUNDRED Klm RIDE THE OTHER DAY, AND IT DID THE SAME THING AGAIN WHEN WE STOPED FOR GAS. MY MACHANIC SAID THE JETS DON'T GET DONE TILL IT REACHES 4 TO 6K Klm THAT SEEMS LIKE A LONG TIME BEFORE ANY ADJUSTMENTS ARE MADE??

C'mon somebody! Please tell BARUA the function of TPS! I can't because I'm standing with BARUA on this topic and want to know more about the TPS :D

PS (Throttle Position Sensor)
TPS (Throttle Position Sensor)

Features of the technology
A throttle position sensor (TPS) has been adopted on the T135 to enable ignition timing control utilizing a 3-D program map based on signals on engine rpm and throttle opening.

Effect (User Benefits)
(1) Outstanding fuel consumption characteristics - Optimum ignition timing in accordance with actual running conditions contributes to excellent fuel economy.
(2) Excellent drivability - The optimized ignition timing means that there is more efficient burning of the fuel droplets in the combustion chamber, which in turn contributes to improved drivability.

mean this thing control ignition ..full throttle mean bigger spark or this sensor ignite when it reading tdc..if yes we can adjust our TPS to get more power and change our BTDC ..bla..bla..

bro Frozen fire

can you verify in your source (not with the service manual downloaded here)
what is the correct color coding in
checking the TPS degree and and TPS linearity as in your
post it has the same color coding for + and - in avo.
see the bold posts.


thanks

Hi Frozen Fire,

How to loosen the TPS nut? Which one is the TPS nut? Do u have a picture of it? I'm confused....

thanks..
