It is never enjoyable to notice an injector noise on your Cadillac DTS. It is a noise that arises repeatedly, usually when you accelerate or your engine is idling. However, this warning sign may be linked to different types of concerns with your automobile injectors. It may not be anything severe, but when a continuing noise shows up, you have to be sure. Most importantly since repairing your Cadillac DTS’s injectors can be costly. That’s why our team decided to prepare this content page in order to help you see more clearly, learn about the different possible failures and determine your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Cadillac DTS, then at the possible causes from which an injector noise may come.
Benefits of the injectors
Injectors are a very important part of the operation of your engine. They were launched to the modern cars about 20 years ago. Before their introduction, 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 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 collected from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their aim 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 triggers of a clicking or knocking noise based on the injectors of your Cadillac DTS
Listening injector noises on your Cadillac DTS may originate from different sources, 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 different sources of these noises and the solutions to be applied to stop them. If you notice another clicking noise but it is not from your injectors, we recommend you to go through this content page about clicking noise on Cadillac DTS to discover the cause.
The causes for injector clicking or knocking noise Cadillac DTS
A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Cadillac DTS have three main tasks, to manage 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 target of improving combustion. If one of these three features 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 as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Cadillac DTS. The main cause of these situations commonly comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably produce a malfunction of the injector.

The consequences of injector noise on Cadillac DTS
Now that we have reviewed the several reasons for injector noise on your Cadillac DTS, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is blocked, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can fairly quickly become serious….
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 repercussions experienced by drivers is a distinctive loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will inevitably have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will fairly quickly damage your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks relating 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 changing your diesel fuel filter regularly>
