It is rarely ever enjoyable to listen to an injector noise on your Dodge Caliber. It is a noise that happens continually, usually when you accelerate or your engine is idling. However, this symptom may be connected to different types of problems with your car injectors. It may not be anything major, but when a frequent noise arises, you have to be sure. Specifically since fixing your Dodge Caliber’s injectors can be expensive. That’s why our team decided to create this article in order to support you see more clearly, learn about the different conceivable failures and identify your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Dodge Caliber, then at the conceivable causes from which an injector noise may come.injector-noise-dodge-caliber

Functions of the injectors

Injectors are a very fundamental part of the operation of your engine unit. They were released 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 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 obtained from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their objective 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 based on the injectors of your Dodge Caliber

Hearing injector noises on your Dodge Caliber may result from different locations, we will now concentrate on the potential causes of these. In most cases, the common noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be adopted to get rid of them. If you listen to another clicking noise but it is not from your injectors, we suggest you to go through this article about clicking noise on Dodge Caliber to discover the reason.

The reasons for injector clicking or knocking noise Dodge Caliber

A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Dodge Caliber have three main missions, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its mission is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three tasks 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 resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Dodge Caliber. The main reason of these situations usually 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 in a malfunction of the injector.

The effects of injector noise on Dodge Caliber

Now that we have reviewed the diverse reasons for injector noise on your Dodge Caliber, we will end by stating the possible consequences of malfunctioning one or more of your injectors. Whether only one is obstructed, or broken, or your entire fuel rail is involved, you cannot escape these consequences which can almost instantly 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 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 inevitably have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will almost instantly damage your cylinders or pistons and your engine may tighten.
Here are three little tips 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 swapping your diesel fuel filter regularly>
