When does my Toyota Yaris 2 make a loud noise?
One way to find a noise from your Toyota Yaris 2 is to identify when it occurs. Indeed, some problems can be linked to parts that are only stressed under certain conditions. It is this method that we will focus on in this first part.
Loud noise Toyota Yaris 2 when accelerating
Loud noise on Toyota Yaris 2 that takes place when you are accelerating can be symptomatic of different failures. Indeed, if you encounter a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will create a much higher noise than during normal process. Moreover, it is also highly plausible that loud noise on your Toyota Yaris 2 is associated with a wheel bearing, which is one of the most common origins of these types of manifestations. Another alternative is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also plausible that the issue may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

When my Toyota Yaris 2 is stopped
If your Toyota Yaris 2 makes a loud noise while not accelerating, engine on, the issue may be connected to poor air intake. An air intake hose that has come loose or has a hole in it may be the reason.

The loud noise comes from the wheels of my Toyota Yaris 2
As we have seen before, loud noise from the wheels of your Toyota Yaris 2 may be connected to two main trouble. If it is one of your tired bearings, it will tend to make a thumping noise that intensifies when it is under stress (spins faster and faster). So keep in mind to examine by driving “fast” (neutral gear on and window open to hear only the noise of the wheels) that the noise is located here, if this is the case swap it or them straight away. If it is a deformed tire, make sure to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Toyota Yaris 2 that is the problem, you will tend to feel a vibration in the direction of the car as you go faster. In both circumstances, you will have to go to your auto technician to replace the tires or perform a balancing.

The loud noise comes from the engine of my Toyota Yaris 2
In case you have identified loud noise as coming from the engine of your Toyota Yaris 2, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be associated with a compression loss during the engine ramp-up phase, so you should encounter a power loss during your acceleration. If the loud noise on your Toyota Yaris 2 is related to air intake, the control will be done mainly visually, check all your air intake hoses by a visual control in your engine block to be sure that it is not damaged or disconnected which would induce an air intake, if it is just disconnected you can reconnect the air intake tubes yourself. Then examine that the engine idle speed is not random. In case you confirm one of these two disorders, take your car to your garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have detected comes from the exhaust pipe of your Toyota Yaris 2, it is highly plausible that you have rust if your car is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your Toyota Yaris 2, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To validate this, get help from someone who will stand under the car while you accelerate to find the exact area of source of this noise. If it is a hole, you can repair it with a putty provided for this purpose, or, if it is a collar, “reattach” it. If it is cut or the hole is too big, it is better to get closer to your mechanic.
