It is rarely ever relaxing to listen an injector noise on your Nissan Pathfinder. It is a noise that comes up regularly, usually when you accelerate or your engine is idling. However, this indicator may be related to different kind of trouble with your vehicle injectors. It may not be anything major, but when a continuing noise appears, you have to be sure. Most importantly since fixing your Nissan Pathfinder’s injectors can be expensive. That’s why our team chose to write this content page in order to help you see more clearly, learn about the different conceivable failures and distinguish your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Nissan Pathfinder, then at the conceivable triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very useful component of the operation of your engine motor. They were launched to the modern automobiles about 20 years ago. Before their appearance, 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 accumulated from the various sensors equipping the vehicle (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 obtain the best possible combustion in the cylinders.
The different causes of a clicking or knocking noise coming from the injectors of your Nissan Pathfinder
Finding out injector noises on your Nissan Pathfinder may come from different locations, we will now center on the potential triggers of these. Generally, the common 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 stop them. If you listen another clicking noise but it is not from your injectors, we advise you to browse this content page about clicking noise on Nissan Pathfinder to discover the trigger.
The reasons for injector clicking or knocking noise Nissan Pathfinder
A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Nissan Pathfinder have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its mission is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three characteristics is altered, the main functionality of the injectors will be disrupted 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 induce thoses knocking or clicking noises on your Nissan Pathfinder. The main trigger of these situations in most cases originates from a particle that gets into the injectors. The accuracy 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 Nissan Pathfinder
Now that we have examined the different reasons for injector noise on your Nissan Pathfinder, we will end by stating the possible effects 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 side effects which can fairly quickly become critical….
First, you risk destroying your exhaust system 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 regular consequences experienced by drivers is a severe loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will fairly quickly 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 swapping your diesel fuel filter regularly>
