R6 tps symptoms

The throttle position sensor TPS is part of your vehicle's fuel management system and helps ensure that the correct mixture of air and fuel is delivered to your engine. The TPS provides the most direct signal to the fuel injection system of what power demands are being made by the engine. The TPS signal is continually measured and combined many times per second with other data such as air temperature, engine RPM, air mass flow, and how quickly the throttle position changes.

The collected data determines precisely how much fuel to inject into the engine at any given moment. If the throttle position sensor and its other sensor partners do their jobs correctly, your car accelerates, cruises, or coasts smoothly and efficiently, as you expect, while maintaining optimum fuel economy.

The throttle position sensor can fail in several ways, all of which result in poor fuel economy at best, and performance limitations that may create a safety hazard for you and other motorists at worst. It can also cause problems when changing gears, or setting base ignition timing. This sensor can fail gradually, or all at once. This is intended to at least allow a driver to get off a busy highway in a safer manner.

Replacing the TPS will include clearing relevant fault codes, and may require software reprogramming of the new TPS module to match other engine management software. This is all best left to a professional mechanic who can provide you with a diagnosis, and then install the correct replacement part. It may feel as though the car simply doesn't accelerate as it should, and jerks or hesitates as it picks up speed. It may accelerate smoothly, but lack power. If these symptoms occur, there's a good chance you've got a problem with the TPS.

When the car accelerates while driving, it usually means the butterfly valve inside the throttle has closed up and pops open suddenly when the driver presses on the accelerator. This gives the car an unintended burst of speed that occurs because the sensor cannot detect the closed position of the throttle. If you start to experience engine misfires, stalling, or rough idling when the car is stopped, it can also be a warning sign of a failing TPS. You don't want to wait to get this checked out!

If the idling appears off, it means the computer is unable to identify the fully shut throttle. The TPS can also send bad input that ends up stalling the engine at any time. This is another failure mode of the TPS, which indicates that it is falsely limiting the power being requested with your accelerator pedal foot. You may find that your car will accelerate, but not beyond a speed of 20 - 30 MPH. This symptom often goes hand in hand with loss-of-power behavior.

Have your vehicle checked for trouble codes to verify the source of the problem. The throttle position sensor is key to getting the desired power and fuel efficiency from your vehicle in any driving situation. As the symptoms listed above make clear, failure of this component has serious safety implications and must be checked out immediately by a qualified mechanic.

A throttle position sensor is similar to the motor cortex in the human brain, it controls one of the most important components of the car that keeps your engine running like a throttle body.

Picture a little module in the car that reads how far down you have pressed the gas pedal. An engine needs two things to stay running which is air and fuel. Normally a car will pick up air through the intake and passes it through the Mass Airflow Sensor.

The air will travel up the intake and it will reach your throttle body. In the old days, there was a wire attached to the gas pedal of your car and it would move accordingly to how you pressed it. Nowadays there is an electric system that's far more efficient than the old ways but it can still have issues. When a TPS goes bad, then the car's throttle body won't function properly. It could either stay shut or it won't close properly which is a severe issue.

If it stays shut then your engine is not going receive air and it won't start. When the throttle gets stuck in an open position than your vehicle will receive too much air and cause it to have a high or fluctuating idle.

Acceleration issues: A bad TPS may cause all sorts of power issues. Your engine may start up but it will have little to no power and it causes it to shut off. On the other hand, it can also cause your car to have spontaneous accelerations even if you didn't step on the gas. Unstable Engine Idle: Faulty position sensors can cause sporadic idle conditions due to fluctuating airflow.

If you see your car misfiring, Idling rough, or stalling out while you drive then you definitely want to have a professional check out that sensor.If you have any problems with the registration process or your account login, please contact us.

Bike: Yamaha R1 Miles: 51, Battery: New still reading 12v Last week my bike gave me an error code so i looked it up in the manual and it said check throttle position sensor.

It ran fine and eventually the code went away, so I didn't worry about it. Fast forward 3 days. Gauges flickered on and off, the tach reading was incorrect it was flipping up and down Now the bike will not start at all.

If you turn on the key, it makes its normal sounds from under the seat, fuel pump kicks on, etc. Has anyone ever had this problem with their bike? Is this normal signs of a throttle position sensor going out?

Join Date: Mar Feedback Rating: 8. I would start with the main TPS then go from there I have heard of this problem before on older R I have an extra at home if you need it but I dont know if it fits. I have an extra TPS sensor from my spare r1 motor, Im in the process of replacing it as we speak. But how would a TPS problem explain the buzzing noise i get as soon as I hit the starter button?

All battery connections are good and tight. No i did not check the charging system, are you thinking it could be the stator that has crapped out on me? Join Date: Jan Feedback Rating: 1.

Charge the battery and then check system output, it should be above I've had batteries read normal at rest, but as soon as I put them under load, they dropped below 5 volts.

6 Symptoms of a Bad Throttle Position Sensor

Members List Member Map. Calendar Garage Forum Home.A bad throttle position sensor is the last thing that you will ever wish to have on your ride. The purpose of a throttle position sensor is to keep your car working by controlling the throttle. With the passage of time, the sensor loses its efficiency and thus has to be replaced. The important question is how to identify the throttle position sensor symptoms so that you end up replacing the right sensor?

Honestly speaking, it is not easy to detect throttle position sensor issues. However, there are specific throttle position sensor symptoms that will ensure you find the culprit. It senses the air, heat, and light, and sends the information to the ECM which adjusts the throttle and fuel supply accordingly. A faulty throttle position sensor sends incorrect information to the ECM resulting in various issues in the engine, its performance, and fuel economy.

Following is the list of the common symptoms of a faulty TPS. In most of the cases, all of these symptoms will show together making it easier to detect the faulty component.

Jerking of the vehicle is the most common symptom of a bad TPS. These jerks can be experienced while accelerating or at high or low speeds. These are random jerks that will disappear at times.

Idle surging can be caused due to other issues in the car but if it happens in conjunction with other throttle position sensor symptoms, the culprit is TPS. At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surging. The check engine light will randomly turn on and off even if the car is running smoothly without any jerks and stalling.

This is often the first ever symptom of a bad TPS. The engine can stall for no reason. The engine can stall at high speed, at low speed, or even at idle. A faulty throttle position sensor will not let your car accelerate normally. Hesitation in acceleration, acceleration surge at both high and low speeds, delay in acceleration, etc. As soon as you see a mix of these throttle position sensor symptoms, you should test the TPS and if it is not functioning properly, it has to be replaced.

Table of Contents.By cycoMarch 18, in Naked. Hi, back in July 06 I had an accident. The motor cutting out made the rear wheel slide as if siezedI managed to bring it back under control but to late and clipped the oncoming car. NOT what some riders are saying!!!!!!!!! Have you had any similar problems? This can even make the bike accelerate or slow down without the rider moving the throttle in rare circumstances.

Throttle body sensor where there has been a lot of info and like wise on a German Forum. Any feed back I would be very gratefull for.

My r6 was laid up for the winter when I started it a couple of weeks ago once it was warm it would not idle it just cut out I have had a recall from yamaha for air filter fixings but nothing about TPS I have spoken to two yam dealers who both said that this recall did not affect the r6 the problem has corrected itself but after 3month lay up there should be no problems with idle it is an 06 bike will wait and see what happens but it is a bit worrying.

Reading this is a concern as i was not aware of this. There are lots of issues even relating to some models, it would seem that even though the TPS has been replaced the problems are still persisting with some.

No matter what Yamaha are saying. Dealer should have all the affected VIN numbers on computer. The problem seems to start around the ml mark and in some cases gets worse as the TPS becomes more worn. There seems to be a lot of confusion about which bikes are actualy on this recall around the world and this is what some of us are trying to clarify as Yamaha themselves were not very clear on the subject in the press reports last October.

Plus of course if you are the second or third owner and not registered with Yamaha as the new owner you would not even get your recall notice letter.

I had the same worries over my MT In the end I phoned them and was told mine was not on the list for recall. For anyone who may have concerns about the TPS recall, you should give Yamaha Customer Services a ring; Have the machine details to-hand, i. You can post now and register later.

The Problem: Yam FZ6N dropped it about a month back, nothing serious just an balance issue, but since then have had an occasional problem with idling and low speed.

The bike usually idles at aboutwill now idle occassionaly at about or under; ie it has a tendancy to cut out at the most inappropiate moments, like low speed lane splitting or waiting at the lights. On the trips where the bike is misbehaving it seems to be running a little rough, normally the engine warning light also comes on. Now the quick and easy fix has been to turn off the ignition and turn it back on, and everything seems hunky-dorey. No immediate causes spring to my mind since your bike is EFI.

Does it use a throttle position sensor TPS? This may have been knocked in your fall and could cause hunting at idle, but turning the ignition on and off wouldn't cure this. If you're certain that turning the ignition on and off does fix it, then it's obviously related to the ecu.

Looks like it could be a case for the dealer The power dropping away when accelerating sounds like a problem I had.

Does it come back and drop away, so it feels like you are on a rodeo bull? I also had to have some throttlewhen stopped at lights. The problem may be with your carbs, they may need balancing. When I had that problem I was switching between 2 and 4 cylinders, hence the bucking effect. The fz6 doesn't have carbs, its fuel injected. The engine may be generating a weak spark, hence the low idling rpm.

This could be related to a dodgy rectifier or coil. As soon as that check engine light comes on, I'd be taking it to a dealer. This doesn't sound like the sort of problem that can be easily diagnosed. I'd be guessing a fuel line or fuel pump.

One may have been dislodged in the fall. Just for those interested, the fault turns out to be a faulty throttle postion sensor, Yamaha knows the problem but is doing nothing about it [-X.

The problem is a little mostiure getting into the resistive sensor causing false readings. Appears as an intermittent fault, that puts a high petrol content into the cylinders. Once the fault appears the only way to get rid of it is to kill the ignition and restart. On my FZ6 the fault occurs when in third gear, with the throttle wound back for about m, and then comming to a stop.By leek74May 1, in Chat!

When i'm riding normal at my own pace the bike runs fine, but when i'm instructing holding a constant speed the bikes juddering as if i keep reving the throttle. I was convinced it was the TPS so tonight i put a meter on the sensor to see what ohms im getting. The info i have says i should see k ohms on the sensor it's self but i readand when its plugged in 0.

I loosened off the pins to adjust it to see if i could get it to the 0. I've got hold of some new throttle bodies complete with sensors which I will put on tonight and hopefully this will cure it. Throttle servo motor on the way out is usually what causes this, seen it a few times and generally does not throw up a fault code. You can post now and register later.
