It is never pleasant to listen to an injector noise on your Lexus UX. It is a noise that happens continually, usually when you accelerate or your engine is idling. However, this sign may be relating to several kind of complications with your vehicle injectors. It may not be anything severe, but when a continuing noise appears, you have to be sure. Specifically since repairing your Lexus UX’s injectors can be costly. That’s why our team chose to create this article content in order to help you see more clearly, learn about the different conceivable failures and establish your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Lexus UX, then at the conceivable reasons from which an injector noise may come.
Purposes of the injectors
Injectors are a very useful part of the operation of your engine motor. They were released to the modern vehicles about 20 years ago. Before their appearance, 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 possibility, 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 vehicle (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 get the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise based on the injectors of your Lexus UX
Listening injector noises on your Lexus UX may result from different sources, we will now center on the potential triggers of these. Generally, the usual noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be adopted to stop them. If you listen to another clicking noise but it is not from your injectors, we advise you to browse this article content about clicking noise on Lexus UX to discover the cause.
The explanations for injector clicking or knocking noise Lexus UX
A clicking or knocking noise from your injectors can be justified by different explanations. Indeed, the injectors of your Lexus UX 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 task is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three functions is modified, 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 as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Lexus UX. The main cause of these trouble commonly comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably end up in a malfunction of the injector.

The effects of injector noise on Lexus UX
Now that we have reviewed the several reasons for injector noise on your Lexus UX, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is clogged, or damaged, or your entire fuel rail is involved, you cannot escape these side effects which can almost instantly become considerable….
First, you risk destroying your exhaust unit 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 common consequences felt by drivers is a distinctive loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly 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 tips 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>
