Yamaha Throttle position sensor problem(TPS)

[Non Stop Racing]

any 1 encounter it before ? even yamaha own mech at hl dont know how to resolve this problem....u can believe it ? wtf man....

[xrage98]

This issue has been going on since i guess the 2004 models came out. I guess almost all 04 and above R1 riders face this problem some time or another. I used to ride an 04 R1. First 15000km was fine then after that it just went sour. My bike would die on me every single time i ride it. Changing the TPS just delays d problem not solve it. Which eventually forced me to change bikes. I loved my R1 but this problem got so annoying that it pissed me off. Heard the 07 R1 have engine dying problems as well. Not sure about the 08's.

I've tried this method, don't scold or **ck me if it doesn't work for you....

 

Here goes....the tps if you read in the link above is like a radio volume knob, when you always leave it at the same position for a long time like in the old type

radios,

 

when you try to turn the volume up or down, you get cracking sound or inconsistent volume control....eg:-you want loud volume, little sound then suddenly the sound from speakers blast out loud.

 

This usually happens to old types of radios with the round volume control knobs.

 

You can either spray some wd40 under the knobs to lubricate the mechanism or switch off the radio and turn the volume knob on and off a number of time and you will not get cracking or inconsistant volume control.

 

Sorry if i am abit long-winded.

 

My spark t135 have a problem of inconsistent engine power previously and after much testing and checking on the internet i found out interesting knowledge about the yamaha TPS.

 

The spark t135 also have TPS, so i applied what i do to the radio to my bike.

 

Using the on and off method, twisting open the throttle full open and close again many times.WARNING:(PLEASE SWITCH OFF ENGINE FIRST AND THE CABURETOR WILL GET FLOODED WITH PETROL)

 

Then you stop twisting the throttle and start the engine(will be abit difficult when engine is flooded)

 

I do this everytime before going out on my bike and now power delivery is very consistent.(When you in the hurry, do not use this procedure as trying to start a engine with a flooded caburetor is not easy work and very fustrating)

 

Hope my idea helps and if you think i'm NUTS don't try it......

Dun worry, it's true about TPS problems. Was told of riders crashing 'cos the sensor doesn't work! IF the riders survive the crash, they come back and complain about the TPS.

 

Sad to say, that's one component that you have to monitor all the time

[cheeko]

even spark135 also have TPS sensor thingy?! oh my god!

hmm..me too had several near miss accidents..due to engine suddenly dying off when i downshift. and when i brought this prob up to agent, i was told "ur riding technique is not correct. try not to clutch in for too long" i was astounded! now blame my riding techniques. lol.. i think a bike should not haf its engine dying no matter how long i clutch in

[Guest tookara]

clutch in should not die wat

wah sey how man like that

This is the tps for spark t135 http://www.yamaha-motor.co.jp/global/asean-touring/machine/technology/img/pic_007.jpg

i can't believe it, even small bikes also got TPS, next maybe they have Fuel injection, and fly by wire. Lucky i buy a honda wave R, Simple & not much headache to maintain

Seems to me that besides xrage98 and chua6389, the rest are just trying to make some sort of a guess-work...no?

 

I myself experience this issue 1 year ago on my 2005 FJR1300, sold to me fr a nice chap in here...

 

there're symptons to this prob, firstly, you'll find that at low revs in Gear 1 & 2, when clutching-in to negotiate low speed manuveours, the engine will suddenly die on you. there-after, some probs in startin the bike.

after starting it, engine might just die suddenly, almost immediately

 

got stuck in GP Esso, at 2-3am!!

 

finally gave-up. Rested the bike for half an hour, the moment it starts again, dashed my way back into SGP.

 

once you're able to reach above 2nd-gear, doesnt seem to be any probs. prob seems to be there at low-speed, esp when clutching-in

 

next day changed the TPS, approx $120, prob solved

[xrage98]

Just like n@kan0 says about the symptoms. For my case changed the TPS and worked fine for a while then months later happens again. Can't be changing the TPS every few mths. Plus it's dangerous to ride in that condition where your bike can just suddenly die off when negotiating a bend.

ohh.... luckily i'd sold off my FJR 3-4 mths after i'd changed the TPS

 

so no idea what happened after that....?? Heng Ah....

yes engine dies at lower speeds and gear 1/2 like tat. and its extremely dangerous esp when u are out 'playing' bike and u need to kick down to gar 1/2. imagine at high rev 8/9k rpm..suddenly ur engine dies.. WTF!

change tps? this is a manufacturing defect. cant always be changing tps. they should find a perm solution to it. we are not paying few hundreds for the bike u know! when honda had a prob for their 929, they did a major recall last time. and so did a few other models. but i have yet to see for the tps prob. the least they could do is find out the problem. but heck, they keep putting the blame on us riders. maybe next bike should consider getting a non yamaha bike.

clutch in should not die wat

 

pls tell that to HL mechanics. thank u bro

Good thing I didn't take over your FJR. I can't imagine if TPS spoilt at Golden Triangle or somewhere along the Mae Hong Son loop

Yup, that's why those who lived to tell the tale come back and complain. HL's hands are tied. It's a design fault.

Me too same boat as urs. Owned a '04 R1 also. Changed TPS a few times. Finally sprayed GT85 to the TPS.

 

All tis problem after a short while wil come back. So pissed off, i cahnged bike also. But missed my R1. One of the sexiest bike ard. Heee.....

if we remove the TPS thing, any prb occur?

[cheeko]

bike will still run, but firing & timing will not be smooth.

[DGray]

And tat wil make things worse instead of rectifying it. Its a big no-no taking out ur TPS.

[frogman]

maybe your TPS needs to be adjusted?

Hey Saniboy,

So what bike you riding now? Used to see u post in the YZF thread last time.

[LollyPoP]

hmm... this TPS thingy happen to most 04 FZ6 & a handful of the 05s.

didn't hear much abt it on the 06 onwards.

[cheeko]

why even small bikes need TPS? Running on good old simple carb is good enough, and also cheaper & less headache to maintain. When bike breakdown also means less 1 components to troubleshoot & replace

Perhaps some newer kups now run on EFI.

TPS is one of the important components of an EFI bike.
