It is hardly ever pleasurable to listen to an injector noise on your Chevrolet Sonic. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this symptom may be relating to multiple types of problems with your automobile injectors. It may not be anything serious, but when a frequent noise appears, you have to be sure. Most importantly since fixing your Chevrolet Sonic’s injectors can be expensive. That’s why our team decided to write this article in order to help you see more clearly, learn about the different possible failures and distinguish your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Chevrolet Sonic, then at the possible triggers from which an injector noise may come.
Purposes of the injectors
Injectors are a very fundamental element of the operation of your engine. They were brought in 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 ability, thanks to the injectors pump, to control electronically each stage of the intake process very accurately (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 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 reasons of a clicking or knocking noise based on the injectors of your Chevrolet Sonic
Finding out injector noises on your Chevrolet Sonic may come from different locations, we will now center on the potential causes of these. In general, the typical noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be implemented to eliminate them. If you listen to another clicking noise but it is not from your injectors, we recommend you to examine this article about clicking noise on Chevrolet Sonic to locate the cause.
The causes for injector clicking or knocking noise Chevrolet Sonic
A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Chevrolet Sonic have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its mission 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 tasks is modified, the main role of the injectors will be disrupted 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 Chevrolet Sonic. The main cause of these problems usually comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably result in a malfunction of the injector.

The repercussions of injector noise on Chevrolet Sonic
Now that we have examined the several reasons for injector noise on your Chevrolet Sonic, 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 major….
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 basic effects experienced by drivers is a noticeable loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk deteriorating 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 recommendations 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 changing your diesel fuel filter regularly>
