It is rarely ever pleasant to notice an injector noise on your Toyota Scion FR S. It is a noise that comes up frequently, usually when you accelerate or your engine is idling. However, this symptom may be connected to different kind of complications with your automobile injectors. It may not be anything major, but when a persistent noise arises, you have to be sure. Especially since repairing your Toyota Scion FR S’s injectors can be costly. That’s why our team chose to write this content in order to help you see more clearly, learn about the different conceivable failures and determine your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Toyota Scion FR S, then at the conceivable reasons from which an injector noise may come.
Purposes of the injectors
Injectors are a very significant part of the operation of your engine. They were launched to the modern vehicles about 20 years ago. Before their arrival, more conventional carburettor-type intake systems were employed, which handled the intake of air and fuel into the engine cylinders. With the injectors, manufacturers now have the opportunity, thanks to the injectors pump, to control electronically each stage of the intake process very precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data collected from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their goal is therefore to inject under high pressure a precise quantity of an air/fuel mixture at a perfect timing to obtain the best possible combustion in the cylinders.
The different origins of a clicking or knocking noise coming from the injectors of your Toyota Scion FR S
Discovering injector noises on your Toyota Scion FR S may result from different sources, we will now look into the potential triggers of these. In most cases, the regular noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be implemented to eliminate them. If you notice another clicking noise but it is not from your injectors, we encourage you to go through this content about clicking noise on Toyota Scion FR S to find the cause.
The reasons for injector clicking or knocking noise Toyota Scion FR S
A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Toyota Scion FR S have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its goal is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three attributes is altered, the main purpose of the injectors will be disturbed and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Toyota Scion FR S. The main cause of these situations usually originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably produce a malfunction of the injector.

The effects of injector noise on Toyota Scion FR S
Now that we have examined the several causes for injector noise on your Toyota Scion FR S, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is clogged, or broken, or your entire fuel rail is involved, you cannot escape these repercussions which can promptly become critical….
First, you risk destroying your exhaust system in the long run, because the unburned fuel residues that will end up in your exhaust system can corrode the metal in it.
One of the most basic consequences experienced by drivers is a severe loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will inevitably have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will promptly damage your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks associated with your injectors and protect you from engine failure:
- Do not drive at the bottom of the tank, as you may absorb impurities
- Use quality fuel
- Think of swapping your diesel fuel filter regularly>
