Hi everyone, glad to be aboard, I'm hoping some kind and knowledgeable soul out there might be able to help me, I am lucky enough to own a 2012 r160 HOWEVER [isn't there always one of them] it ain't behaving, I got it at 2800 ks at it has been pure heaven up until 11,500ks
at which point its started to run rough at low revs and cuts out as I'm changing down to a stop, the boys down at the dyno shop tell me the throttle position sensor is worn and is telling Mr ESU to squirt more fuel than required and flooding the motor. 500 big ones from benelli OUCH
I have picked up from reading other threads that they are a BMW PART and easy to come by ,but not sure how,why,where, any info would be muchly appreciated CHEERS

Welcome Steve,i had my t.p.s replaced last year with a new part by Bennetts of Barnsley (U.K.) during a service and was charged £75 for the part.It might be worth sending them an e-mail or give them a call. Sorry don't have the number handy but it's on the forum.Hope this helps,Graeme

TPS result

Hi Guys ,I finally have a result for my r160 tps problem. Thanks to this forum and good old ebay . the item is a TPS for bmw 3 series 92-2000 models and is sold for $86au plus $36 del at a2zspares out of England
it has been fitted and works yippee. As a point of interest the only 3 r160's that I personally know about, are all 2012 models and all 3 have had the same problem kick in at around 12,000ks, so it would be interesting to know if this is just a coincidence or a common problem.
cheers

G'day Steve
I have had a pretty ordinary time trying to resolve this TPS issue (as refferred to by Errol). I tried two aftermarket TPS (non genuine BMW) and they were not compatible. The voltage would not go low enough to do a reset. I'd be very interested to see if yours was able to be reset or if you just replaced the faulty one and ran it?

I eventually took the one off my R160 track bike and put it on my road bike which solved the issue but it seems to be a bit erratic now as well. Keen to know if the genuine BMW (Hella) one is within spec.

BTW I'm out at Boonah if you want to go for a spin sometime. There are about 4 of us that I know of.

Hi Mark, the after market TPS we sourced through Ebay have worked just fine, we have fitted them in to 2 bikes now both successfully, having said that it was necessary to rebalance the throttle bodies and dyno tune both bikes which was done by the guys at

Found this on eBay Australia and seems to be a good price if the correct TPS.
Being located in Oz, it could be a rapid and relatively cheap option for Oz owners.
The listing details all BMW models it is used on.

NEW Quality Throttle Position Sensor FOR BMW 323i 323TI 325i 328i E36 | eBay

As the link will probably not work after some time, suggest you search for New-OEM-QUALITY-Throttle-Position-Sensor-For-BMW-323i-323ti-325i-328i-E36

I was looking in the workshop manual I have for a TNT 1130 at the coil specs and lo and behold the BMW part number is there for the TPS.

BMW 13631721456

A quick look on eBay found many and some at a very good price.

These are the ones I used. They DO NOT WORK. I tried two of them. Voltages were way out and a fair bit apart. Just use a known b rand ie Hella etc.

Great to know that. I know that with Ducatis the TPS type depends upon the ECU.
Those, like mine, with 16 x 16 tables, the TPS resistance is non linear. Up to 30 degrees the resistance slope vs TP is steep to provide accurate TP angle to the ECU.
On later ECUs the tables are 20 x 32 where TP is 20 break points. In these the resistance slope is linear vs TP, I guess as the extra 4 TP break points allow greater accuracy at low TP.

Maybe one of these is the case for the Benelli TPS and certain BMW models.

The "end to end" resistance of the TPS does not matter, as it is just used as a potential divider to input a voltage to the ECU.
What does matter is how the resistance changes (as above) with throttle angle. If the resistance/voltage is wrong, then the ECU is looking in the wrong part of the map for the real butterfly angle.

You're a bit smarter than me in relation to the ins and outs of electrical components but when it came to resetting these aftermarket TPS's the voltage was on both occasions too high and of course could not be reset. WOT voltage from memory was OK.

Interesting. Maybe there is an extra resistor in those TPS at the "bottom end" between the ECU negative and the bottom of the TPS potentiometer.

Any way, your experience is that they do not work and that is valuable info.
Maybe the ECU has some built in voltage limit that resetting cannot be applied to.
Resetting Sagem is different to resetting Walbro ECUs.

I have drawn up the attached on TPS operation.

Hi, I have just picked up my S./H R160 from Olivers in Brisbane. Advertised with 9k but has nearly 12. Never mind, let the buyer beware. Anyway it is having the same issues as yours. Running like crap and stalling once even slightly warm. I will hunt down one of those BMW TPSs and give it a try. Was the TPS from a 4 or 6? They may be the same. I will post how it all goes. Now to head into the manual to see how its done. Thanks for the info.

Hi Mate! I have some spare tps if you need 1. Its from LOWE Germany same exact part from HELLA. I believe its the same for the bmw's listed. It work for my 2013 899 and mates 2009 1130.. it should work on the r160's. Im in melbourne can post if you need to.. bought for $43 on ebay. I can ship it to $50. Let me know if your interested.

Oh BTW once you intsalled it make sure you also do a good clean of your TB with cleaner and spray some on your stepper aswell.. it will run like new.. its also a good practice to do a reset TPS on tuneecu if you have the cables..

Sadly this one is the same as the others. Tuneecu says on attempted reset words to the effect "Voltage to high"
All idle stops wound right out.

It can can have a rest now as the starter clutch is buggered so I have time to explore TPSs further.
Anyone know the best place for starter clutch parts? Maniac I suspect.

TPS will not reset

Hi,

After much work replacing the starter clutch and finding some pretty dodgy workmanship( Starter clutch screws fell out once the circlip was undone) Alleged new starter clutch not long ago. Anyway tried two BMW type TPSs. Throttles totally closed. Voltage to high to reset?

Ideas? May just have to buy a genuine one. The original unit resets fine. When it used to run it was extremely rich. It has a new stepper motor and I have down loaded better map.

Sounds a lot better when turning over. Not like the engine is about to explode.

Ideas on TPS please.

Hi Trotts sorry to hear the TPS I sent you didnt work. A bit puzzling as it worked on my 899 and mates 1130 and share the same Hella TPS.. Maybe the R160 is different I dont know. What version of tune ecu do you have? Have you tried using different version? I did remember my mates 1130 had the same problem resetting his OEM Factory TPS before he changed it and tried downloading the most current version and it worked.

Ideas on TPS please.

There's a bloke on gumtree au selling original Hella TPS. I think around $70+. His name is Sinh or Craig. Try this link

He said he use to be one of benelli dealership in sydney.
