The emission system in your vehicle play a great significance when it comes to minimizing the amount of pollute emitted in the environment. However, being a very delicate part in the car, it can sometimes develop issues like any other intricate part in the car. Although Honda vehicles are well known for their performance and reliability but emission system problem Honda are still there. If you own a Honda and you have come across an emission system warning light, then you are among the many. Here let’s reflect upon the types of emission system problems with Honda vehicles, their possible causes, signs of their presence and how to deal with them.
What is the Emission System?
Before going deep into the problems, we will need to clarify its functions of the emission system. As you may probably imagine it is applied to controlling the generation of the toxic gases which are evolved by the engine of your car. The components through which specific task in regard to emission of pollutants is achieved are:
- The catalytic converter
- The oxygen sensor
- The exhaust gas recirculation valve (EGR)
- The evaporative emission control system (EVAP).
What Does Emissions System Problem Mean On Honda?
The emission system in Honda vehicles means the ability to regulate as well as limit exhaust emission based on environmental standards. However, existing issues in this system may occur. Since there are many reasons that can cause higher emissions and consequently fail the emission test. The emission system problem Honda vehicle mainly originate from the problems with oxygen sensors, catalytic converter. And exhaust gas recirculation valve or EGR. These are important in the measurement of the oxygen amount in the exhaust gases. Reporting this data to the engine control unit (ECU) for tuning of the air/fuel mixture for combustion.
Defective oxygen sensors can make a car less efficient in terms of fuel consumption and more of a polluter than it should be. Likewise the ‘catalytic converter’ which helps in transforming dangerous gases which include carbon monoxide and nitrogen oxides among others to less hazardous ones also can be full up or ruined in some manner cutting its efficiency.
A mechanically operated valve, the EGR stands for Exhaust Gas Recirculation and it is designed to pump a part of the exhaust back to the engine cylinders; The valve might be blocked with carbon deposits which interferes with the process of the circulating gases and increases the amount of NOx emissions. Identifying these problems requires the use of scan tools to interface with the car’s ODB, check on the components for signs of damage, corrosion or wears. Also subsequently repair and replace them for efficiency of the emission system to conform to set standards.
Many of emission system problem Honda vehicles can be prevented if the emission system’s warning lights are not neglected. Moreover, attended to before they become major problems that defy environmental standards.
Emission System Problem Honda – What are the Symptoms?
Before adopting any solution first of all you should have to clearly verify whether your Honda vehicle have the emission system problem or not. So, for this you should consider the following symptoms to ensure the emission system problem in your car.
Check Engine Lights
The check engine light or malfunction indicates an important part of your car’s onboard diagnostics and the light often signals a Honda Pilot emissions system problem. This given light may indicate a trivial issue. Such as an loose gas cap or a serious issue like damage catalytic converter or a faulty oxygen sensor. In Honda cars there is always a sign that check engine light emission and for this must be checked by a mechanic in other not to cause more damage to the car.
Failure to pay attention to the light can result in an unfavorable decline in the fuel economy, high emission rates and, or the failure of other pricier parts. In an attempt to identify the root cause. An engineering scan tool can be used to download fault codes from the vehicle’s computer which may give more explicit details of what may be going wrong. Solving these problems may require basic or technical procedures. But you should seek these services immediately to keep your car running for many years.
Rough Idling
A very ratty idle or anything that makes it shake or not smooth is an ideas that emissions are bad. Shaking or vigorous vibrations of the engine during idling may be caused by faulty oxygen sensors or damaged catalytic converter.
Emissions Test Failure
As any mechanic will tell you, if your vehicle fails an emissions test there is definitely an issue with the emissions system. This failure can be as a result of some problems that might be associated with the following:
- Catalytic converter
- Oxygen sensors
- Evaporative Emission Control (EVAP) system.
Engine Misfires
Excessive engine misfires can therefore be an indication of an emissions related issue. Anything like a damaged spark plug or a damaged catalytic converter will hinder the combustion process leading to misfires.
Smoke from Exhaust
Smoke emanating from an automobile exhaust system which may be black or blue in color may indicate major emission problems. This is most of the time, an indication of unburned fuel, oil leakage or even other major engine problems.

Loud Engine Noise
Unusual or loud noises when the engine is running are a sign that the emissions system has failed. Broken exhaust parts or sometimes a damaged catalytic converter increases the noise coming out from the engine.
Common issues with Honda’s emission system
There are the common issues mentioned which help you to resolve the emission system problem in your honda vehicle.
1- Faulty Oxygen Sensors
An oxygen sensor measures the level of oxygen within the exhaust gas and relays this information to the computer within the vehicle to modify the air fuel ratio. A bad sensor can cause the wrong fuel/air blend impeding performance and also increasing pollutions. Reduced fuel efficiency, stony engine rundown, and a check engine light. Just replacing the faulty oxygen sensor can rid the problem. And also help in getting proper functioning of the engine.
2- Catalytic Converter Issues
Another important part, catalytic converter, minimizes poisonous emissions by changing them into less dangerous releases before they leave the exhaust. It can block or be damaged by long exposure to high temperatures or richness in fuel air mixtures. Decreased power output, bad smell like that of an egg and the enhanced emission of gases.
The catalytic converter may require cleaning or replacement if it has become blocked or is otherwise rendered in efficient.
3- EGR Valve Malfunction
Exhaust trucking regulation is whereby a portion of the exhaust gases is pumped back into the engine through the EGR valve hence reducing nitrogen oxide formation. But if it becomes stuck or chocked it then hampers the running of the engine all together. Shaky, low-speed fuel consumption, poor emission test results.
The trouble can be solved by cleaning or replacing the EGR valve.
4- EVAP System Leak
The other system known as EVAP system is used in avoiding the escape of fuel vapors into the atmosphere. Solutions in this system may cause the check engine light and also affect emissions. Fuel smell inside the car, light on the dashboard, and poor performance during emissions test.
How to Manage an Emission System Problem?
Emission systems are among the most important components in today’s automobiles, precluding the dangerous release of pollutants into our atmosphere.
