It is never pleasurable to listen to an injector noise on your Honda Pilot. It is a noise that arises repeatedly, usually when you accelerate or your engine is idling. However, this symptom may be connected to multiple sort of complications with your car injectors. It may not be anything severe, but when a recurrent noise happens, you have to be sure. Most importantly since repairing your Honda Pilot’s injectors can be expensive. That’s why our team decided to create this content in order to support you see more clearly, learn about the different possible failures and establish your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Honda Pilot, then at the possible causes from which an injector noise may come.
Functions of the injectors
Injectors are a very important element of the operation of your engine unit. They were released to the modern cars 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 opportunity, 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 compiled from the various sensors equipping the car (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 origins of a clicking or knocking noise caused by the injectors of your Honda Pilot
Experiencing injector noises on your Honda Pilot may come from different origins, we will now look into the potential triggers of these. In general, the usual noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be adopted to prevent them. If you listen to another clicking noise but it is not from your injectors, we advise you to examine this content about clicking noise on Honda Pilot to locate the reason.
The reasons for injector clicking or knocking noise Honda Pilot
A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Honda Pilot have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its objective is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the aim of improving combustion. If one of these three tasks is altered, the main purpose of the injectors will be disturbed 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 provoke thoses knocking or clicking noises on your Honda Pilot. The main reason of these trouble commonly originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably end in a malfunction of the injector.

The side effects of injector noise on Honda Pilot
Now that we have examined the different causes for injector noise on your Honda Pilot, 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 repercussions which can promptly become severe….
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 felt by drivers is a noticeable 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 promptly harm your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks connected 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>
