Being the target of recurring problems on your car is really frustrating, furthermore the economic side that these problems represent, one must also add the time lost with a non-functional Scion xB and the time spent to identify and solve the malfunction. However, some problems are less severe than others, which is not to say that they do not stress us. In this article we are going to look into a issue that can occur to many of us, having vibrations at acceleration on Scion xB. This issue can often be hard to perceive but it must be looked after. We will consequently start our content page with the origins of these vibrations on Scion xB, then, with the solutions you have to reduce or stop these tremors.

Why does my Scion xB emit vibrations when accelerating?

So let’s start our content page with the origins of this type of issue on your car. You should already know that an engine, especially if it is ancient or if it has been driven quite a bit, can naturally vibrate without being a issue behind it. Large diesel engines, especially those with a lot of torque, can trigger this kind of impression, both at idle and when accelerating.

I feel vibrations on my Scion xB only when accelerating

Let’s take the most interesting circumstance for us in this content page. The simple fact that you experience trembling on your Scion xB during your acceleration phases, in this circumstance you will have to examine the state of several parts because several of elements can be at the origin of these vibrations and even if you are unfortunate a mix of several of them may also be possible, here is the list of parts that can be concerned.

  • Turbo: If the turbo of your Scion xB is defective, it may trigger vibrations that you will feel when you accelerate at the moment it is running.
  • The turbo pressure sensor: This sensor will manage the pressure exerted in the turbo of your car, if it fails it may affect the performance of your turbo and create vibrations that you may experience at the time of acceleration of your Scion xB.

    • .

  • If the turbo is punctured or damaged, the consequence will be similar, the power supply of your turbo will be disrupted and its performance too. Be sure to visually verify their condition.

I’m feeling vibrations on my Scion xB at acceleration and deceleration

We will now focus on the case where you experience vibrations on your Scion xB when you are accelerating but also when you are idling. If you only experience vibrations when you are idling on your Scion xB, please consult our content page focused on this issue to fix your problem. If, however, you identify that your Scion xB vibrates when accelerating but also when it is stopped, here is the list of items to verify:

  • EGR valve: In actual fact this valve which manages the return of exhaust gases for pollution standards can become dirty and disrupt the evacuation of exhaust gases which can trigger Scion xB vibrates when accelerating but also when stopped.
  • Injectors: Your injectors that regulating the fuel/air mixture flow may be dirty or damaged, which will release the wrong amount of mixture and thus prevent your engine block from working effectively, it is even possible that one or more of your cylinders are not running correctly.
  • Fuel Filter: Like the injectors, if the filter is clogged it will not let the fuel pass correctly and therefore disrupt the performance of your Scion xB, up to the point of producing vibrations during acceleration.

Here are the main motives of a Scion xB that vibrates at acceleration

What can I do to stop the vibration when I accelerate on my Scion xB? What can I do?

Finally, in this last part, we will give you the possibilities available to you to cure these tremors on your car when you accelerate. Here is the best attitude to adopt according to the component that is involved:

  • Turbo: If your turbo starts all these vibrations when you accelerate your Scion xB, it will be good for you to control all the parts associated with it because changing a complete turbo is a big budget and most of the time the issue does not come exclusively from the turbo. So be sure to examine your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Scion xB to your mechanic.
  • EGR valve: The EGR valve has the benefit that it is often easy to access and simple to take apart/clean. You can always look into it and clean it, for this see our content page on cleaning the EGR valve of an Scion xB.
  • Injectors: Injectors are very sensitive parts and a few impurities may be enough to disrupt their performance. Use a fuel additive to simply clean the injectors, if this is not enough you will have to go to a expert.
  • Fuel Filter: If it is the fuel filter, simply change it. A fuel filter doesn’t clean itself, so if it is clogged you will just have to replace it with a new one.

Now you have all the information you need to uncover the origin of the vibrations at acceleration on your Scion xB. If you don’t feel able to complete certain operations don’t hesitate to go to your motor mechanic.
