Yamaha Throttle position sensor problem(TPS)

[antonioshabirto]

how do yamaha TPS differs from others. Do they use Software to reset the TPS?

 

will changing to a better ECU solve the problem ?

 

I am just puzzle and curious.

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

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

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

 

Im not so lucky le... i jus bought my FZ6 bout 3mths back... recently i encounter the TPS prob le... start bike idle can suddenly dies off... den diffcult starting up... when clutch in free roll at idling rpm oso dies off... took my bike down to HL and guess wat they told me... my clutch biting point set too near... and idling too low... which both i oso thinking shouldnt b the case... and eventually a grand finale took place last week... dies off whenever i hit junctions slowing down... and eventually dies on me, cant start at all. thou ignition on bike not start but headlight on, rpm needle flickering like im revving the bike, error code 16 comes out. So i left it there and mingle around with the ignition finally got the bike started and speed all the way home luckily expressway all the way but once exit the expressway bike dies again... from other forum website i found out dat is error code 16 is TPS... called HL and they ask me to put the bike and check cos now bike is safely running... and they need a week or so... and no claim for transportation while this period of time... haiz...

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....

 

Does this mean that the new Yamaha rides have this issue?

Besides changing the TPS, you guys can also try to lift up the tank, take out the TPS and use GT85 to spray it in to clean out as you rotate the TPS.

 

This thing is like a potentiometer. It senses your rotational position and sends a signal to the ECU. Heard that there's some kinda grease in the TPS for lubrication, and after awhile the grease breaks down or something and leaves deposits that impair/degrade the signal sent back.

 

I did this 3 yrs back on my 04R1 and used GT85 to clean out the internals of the TPS. No cost.

 

Fixed my problem permanently.

 

 

Try at your own risk.

 

 

 

Edit: Oops. Just saw the Racewerks tips. Yeah... Do EXACTLY that.

Or if not sure, just send your bike there and ask Norman.

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

 

Hi Gucci,

 

Same as me haiz

WHere to buy the spary ? how much ? have to maintance It ?

please advise

Get the new TPS from Hong Leong.

 

Or, just head to Racewerks if you wanna get the current one serviced. Saves more $$

Just being curious.

Suzuki EFI bikes employ TPSes since its GSXR750s of in '96 & '97.

But up to date, never heard of it having mass failures like on this scale.

 

TOS (Tip-Over-Sensor), yes but was rectified early.

Its been on for so many years but wondering why Yamaha couldn't rectify what seems to be a design fault only...

[ganman]

HL held a major recall sometime last year for the TPS...

 

My Fazer did die on me once... electrical system all functioning fine but engine just died. It was a 05 model... But only encountered this once and it started up fine a min later. Some of the others had more frequent "breakdowns".

[deanz4]

my friend just changed his TPS 02 fjr for 110..ahaha so ex

[Erotomania]

maybe u guys shld petition try complaint email to yamaha japan abt this TPS issue & tell them even the yamaha agents in SG also cant solve the problem & tell them very disappointed with yamaha technologies...blah....blah....

Hehehe! R* is expecting a PC version in about a year's time.

Meanwhile, I'm blasting away gangstarz on an NRG900 sportsbike.

 

One love, breda!

Oh 1 year. That's long.

 

And I just upgraded myself to a fully Crysis capable system last month. LOL. Wasted... wasted indeed.

Well, we're having troubles on both the PS3 and 360 console.

The game really devoures a LOT of resources.

 

Imagine high-res detail consistent for an entire metropolis city.

A fren has gotten 3ROD problems on his 5-months old 360 just by playing GTA4 but plays perfectly fine with other games.

 

But the problem is apparently worser with PS3 consoles.

Totally random freezes and lockups. Some say it even destroys the game profile and saves onboard the HDD.

Ouch. So much problems eh.

 

Well hopefully by the time the PC version comes out, they'll solve some of the ingame issues.

[Running_Man]

This sucks. I just pad deposit for a 2nd hand 04 R1.

Hope this problem has been fixed by previous owner.

[spaiduhz]

I take it that WD40, being kerosene based, cannot be used to flood-clean the TPS?

 

it does seem unfortunate that Yamaha would have this problem for so long left permanently un-rectified. :/

hey tks all guys for your input.

tps is a serious b1tch aZz problem tt even yamaha cant do anything or able to give full detail how to solve it.

 

Recently went to yamaha to fix it, the fat spec wearing mechanic cant do anithing about it,leave the bike for 3days, know what he do ? he say he juz ride 2 times testing, tell me bike is wonderful no problem. wtf . in the end charge me 50$ for labour.

 

thus i went to ubi motor factor, they wash the throttle bodies and spray with some liquid and airblow it, currently now so far so good. but if spoil again ..damm , i muz go replace the tps. Total cost ? 80 .

 

HL seriouslly slacker or lack of knowledge ? kudos to the fat mechanic who still can smile at me n ask me to enjoy my bike when i take it out from hl. Sorry if i sound bias but that is the same mechanic when i encounter code 59(TPS) whom he advise me to ignore it and go ride for few days see how. eventually i endure 1week of **** performance before gerald of HL fix the problem for me.

 

So if u guys thinking of going HL , muz be firm n **** the sh1t of that fat **** . good luck

This is a much debated problem and there seem to be many old wives tales surrounding the issue. I used to ride the 2004 R1 and my TPS broke down after about 1 year's usage. Bought the TPS from HL and went off to another workshop borrowed the tools and fit it up with another mechanic to speed things up. After that conducted a proper VTS. The result was a good use of it since then until I sold the bike in late 2006. The new owner also did not complain of any TPS problems till today.

 

The TPS is basically a potentiometer that collects parameters to determine the position of the trottle body valves. That is why the engine cannot hold idling when the TPS is faulty. The TPS itself is a non-servicable item. It has to be replaced whole and not tampered with. Therefore replacing the water-repellant grease inside does not help but worsens the problem. Grease itself is a graded item and as we do not know the grade to replace, it is best not to play smart alec.

 

After replacing the TPS, we must do a proper valve throttle body synchronization. This is because during the malfunction, the throttlebody will lose the synchronization it was previously calibrated with. By replacing the TPS through the bike shop, this calibration service should be complimentry. And I doubt those self service owners who replace themselves have the proper equipments to do it. To specially conduct the synchronization warrants about $80 as it means extensive labour. But by replacing the TPS, you have already paid for the brand new TPS, you get them to remove the same components anyway. At the end of it, you have a pair of brand new TPS, properly done up service and you can also demand for warranty from the bike shop that if it fails in the next month or so they should take responsibilities.

 

In the end, it is money well spent. Being in the automotive sector, I have seen some really stupid modifications and yet hailed themselves as experts despite their folly. The worst is to spread the wrong info to the next owner and bad mouth the manufacturer on the wrong basis.

 

Workshops themselves are also run by mechanics made of flesh and blood and they will make mistake, they will err.

 

As manufacturers, the responsibility to take work seriously and not brush off any enquiries is a basic requirement. No matter what, a customer with a problem on his machines pays the salary. HL have their good and bad side. But being the agent and not the original builder, they are limited to the things they can do. This is even more amplified in the 4wheeler industries.

 

But as owners, we always have the right to search for a second opinion from reliable sources. I will keep the bad comments at home as one faulty mechanic or a few faulty machines I know does not equate to a global feedback. If you are unsatisfied with the service or products, there are plenty of avenues you can redress your injustice.

 

Good luck.

Replacing the TPS is one solution, bro.

 

But before that, they can also try the DIY stuff and use GT85 on the TPS. Doesn't hurt. If that fails, then go for the replacement.

The problem is short circuiting the TPS can lead to damages to the engine ECU. And by doing the DIY stuffs, still need to spend $80 to get the V/v throttle synchronization done when a mere $200 you can get a pair of brand new TPS and complimentry V/v throttle synchronization done plus warranty isn't it a more economical and technically sound solution? It will be good if the DIY stuffs works and the $80 done on the VTS well spent. If it fails, still gotta re-do and spend another $80? Doesn't seem financially sound. And expelling the water resistant grease doesnt seem technically sound too. When I brought this issue up during meetings in Germany, it invited a lot of laughters from my colleagues all over the world. They explained that there're also 'gurus' in Europe and the States. Well... to each his own. I just offer my advise when I see things on a macro view.
