It is never relaxing to listen to an injector noise on your Toyota Iq. It is a noise that happens regularly, usually when you accelerate or your engine is idling. However, this warning sign may be related to multiple types of complications with your car injectors. It may not be anything serious, but when a continuing noise arises, you have to be sure. Especially since replacing your Toyota Iq’s injectors can be expensive. That’s why our team decided to create this content in order to help you see more clearly, learn about the different conceivable failures and distinguish your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Toyota Iq, then at the conceivable triggers from which an injector noise may come.injector-noise-toyota-iq

Benefits of the injectors

Injectors are a very fundamental part of the operation of your engine. They were released to the modern vehicles about 20 years ago. Before their introduction, more conventional carburettor-type intake systems were used, which handled the intake of air and fuel into the engine cylinders. With the injectors, manufacturers now have the ability, 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 accumulated from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their purpose is therefore to inject under high pressure a precise quantity of an air/fuel mixture at a perfect timing to get the best possible combustion in the cylinders.

The different triggers of a clicking or knocking noise coming from the injectors of your Toyota Iq

Listening injector noises on your Toyota Iq may result from different locations, we will now look into the potential triggers of these. Generally, the typical noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be applied to prevent them. If you listen to another clicking noise but it is not from your injectors, we suggest you to go through this content about clicking noise on Toyota Iq to discover the cause.

The reasons for injector clicking or knocking noise Toyota Iq

A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Toyota Iq have three main missions, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its task is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three attributes is altered, the main functionality of the injectors will be disturbed and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Toyota Iq. The main cause of these trouble generally originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably lead to a malfunction of the injector. If after checking, this noise originates from another component of the engine of your Toyota Iq, have a look at this content for more infos.

The effects of injector noise on Toyota Iq

Now that we have reviewed the several reasons for injector noise on your Toyota Iq, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these repercussions which can almost instantly become considerable….
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 known repercussions felt by drivers is a significant loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will almost instantly affect your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks linked to 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>
