It is never relaxing to listen to an injector noise on your Jeep Grand Cherokee. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this indicator may be relating to several kind of complications with your vehicle injectors. It may not be anything severe, but when a persistent noise arises, you have to be sure. Especially since fixing your Jeep Grand Cherokee’s injectors can be costly. That’s why our team chose to prepare this article content in order to help you see more clearly, learn about the different plausible failures and establish your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Jeep Grand Cherokee, then at the plausible causes from which an injector noise may come.
Functions of the injectors
Injectors are a very fundamental component of the operation of your engine motor. They were brought in to the modern vehicles about 20 years ago. Before their arrival, 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 vehicle (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 get the best possible combustion in the cylinders.
The different origins of a clicking or knocking noise caused by the injectors of your Jeep Grand Cherokee
Experiencing injector noises on your Jeep Grand Cherokee may originate from different sources, we will now focus on the potential causes of these. Generally, the usual noise of a faulty injector is of the snap type. Here are the several 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 advise you to examine this article content about clicking noise on Jeep Grand Cherokee to find the cause.
The reasons for injector clicking or knocking noise Jeep Grand Cherokee
A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Jeep Grand Cherokee 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 control the air/fuel dosage and at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three functions is altered, 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 because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Jeep Grand Cherokee. The main cause of these problems commonly comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably end up in a malfunction of the injector.

The repercussions of injector noise on Jeep Grand Cherokee
Now that we have analyzed the several causes for injector noise on your Jeep Grand Cherokee, we will end by stating the possible end result 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 fairly quickly become critical….
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 noticed 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 undoubtedly 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 tips 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>
