Why does my Toyota Sienna release vibrations when accelerating?

So let’s commence our article with the roots of this form of issue on your car.

Large diesel engines, especially those with a lot of torque, can bring about this sort of sensation, both at idle and when accelerating.

I feel vibrations on my Toyota Sienna only when accelerating

Let’s take the most interesting circumstance for us in this article. The fact that you come to feel trembling on your Toyota Sienna during your acceleration phases, in this scenario you will have to check the state of some elements because various of elements can be at the origin of these vibrations and regardless if you are unlucky a mix of several of them may also be possible, here is the list of components that can be concerned.

  • Turbo: If the turbo of your Toyota Sienna is faulty, it may bring about vibrations that you will feel when you accelerate at the moment it is activated.
  • The turbo pressure sensor: This sensor will manage the pressure exerted in the turbo of your car, if it fails it may disturb the behavior of your turbo and deliver vibrations that you may feel during acceleration of your Toyota Sienna.

If, on the other hand, you identify that your Toyota Sienna vibrates when accelerating but also when it is stopped, here is the list of components to examine:

  • EGR valve: In truth this valve which controls the return of exhaust gases for pollution standards can become dirty and disrupt the evacuation of exhaust gases which can bring about Toyota Sienna vibrates when accelerating but also when stopped.
  • Injectors: Your injectors that control the fuel/air mixture flow may be dirty or damaged, which will discharge 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 properly.
  • Fuel Filter: Like the injectors, if the filter is blocked it will not let the fuel pass properly and therefore disrupt the performance of your Toyota Sienna, up to the point of leading to vibrations during acceleration.

So make sure to take a look at your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Toyota Sienna to your mechanic.
  • EGR valve: The EGR valve has the advantage that it is generally easy to access and easy to disassemble/clean. You can always take a look at it and clean it, for this see our article on cleaning the EGR valve of an Toyota Sienna.
  • Injectors: Injectors are very sensitive components and a few harmful particles 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 professional.
  • Fuel Filter: If it is the fuel filter, just change it. A fuel filter doesn’t clean itself, so if it is clogged you will only have to replace it with a new one.
