The Common Emission System Problem In Honda Vehicles
Although Honda vehicles are known for their reliability and performance, like any complex machinery, Honda vehicles are not immune to occasional issues and the emission system problem Honda is one of these. Whether you own a Honda Civic, Accord, CR-V, or any other Honda model, you might have experienced is related to the emission system. Let’s go deep into the world of Honda emission system problems and find out how to tackle them effectively.
What Does Emissions System Problem Mean On Honda?
When you encounter an “emissions system problem” in a Honda vehicle, it refers to an issue or malfunction within the vehicle’s emission control system. Like in any other model vehicle, Honda’s emission system is designed to reduce harmful pollutants emitted into the atmosphere as a result of the combustion process.
The emission control system in a Honda is structured based on various components that work together to minimize the release of pollutants such as nitrogen oxides (NOx), carbon monoxide (CO), and hydrocarbons (HC). These components include the oxygen sensors, catalytic converter, exhaust gas recirculation (EGR) valve, evaporative emission control (EVAP) system, and more.
When the Honda’s onboard diagnostic system detects a problem or a deviation from the expected performance of the emission control components, it triggers the “emissions system problem” warning or check engine light on the dashboard.
When the “check emission system Honda” light activates on the Honda’s dashboard, it implies that the Honda emission system isn’t working properly. Sometimes, it could be a simple issue like a loosened gasoline cap, however, you also need to have a quick diagnostic as soon as possible.

Emission System Problem Honda: What Are The Symptoms?
The symptoms of Honda’s emission system can vary depending on the specific issue affecting the emission control system. Here are some common signs to look out for:
Check engine light
The most obvious symptom of a Honda emission system problem is the illumination of the check engine light on the vehicle’s dashboard with the message “check emission system”. The check engine light serves as a warning that a problem has been detected. However, it doesn’t provide specific details about the exact issue, so it’s important to have the vehicle scanned for diagnostic trouble codes (DTCs) to identify the specific problem.

Failed emission test
If you live in an area where periodic emissions testing is required, an emission system problem can cause your Honda to fail the test. Failed emissions tests are often due to increased levels of pollutants being emitted from the vehicle, indicating a problem with the emission control system.
Unusual exhaust smoke
Let’s pay attention to the color and consistency of the exhaust smoke coming from the tailpipe. In some cases, an emission system problem can cause the exhaust smoke to be thicker, darker, or have an unusual color. If you notice excessive white smoke, black smoke, or a strong odor in the exhaust may indicate an issue.
Reduce fuel efficiency
Another symptom of a failed Honda’s emission system can also cause a decrease in fuel efficiency. When you notice that your Honda is consuming more fuel than usual or that you’re having to refuel more frequently, it could be a sign of an emission system problem.
How To Fix The Emission System Problem Honda?
Whenever you notice the error message “check emission system” on your Honda dashboard or any other symptoms we listed above, it’s time you fix or diagnose the emission system. How you might be able to go about fixing it?
Before going into detail methods, we will find out about what are the causes of the Honda emission system:
- Faulty catalytic converter
- EGR system issues
- Fuel system problem
- Evaporative emission control (EVAP) system leaks
…
When you encounter an emissions system problem on your Honda, it is important to address it promptly. Ignoring or neglecting the issue can lead to some serious damages, which may result in the vehicle failing an emissions test or being non-compliant with environmental regulations.
Retrieve diagnostic trouble codes (DTCs)
When the check engine light illuminates, it indicates that the vehicle’s onboard diagnostic system has detected a problem. The first step is to use a diagnostic scanner to retrieve the DTCs associated with the emission system problem. These codes provide specific information about the component or system that is experiencing the issue.
Check other parts of the emission system
You can inspect the various components of the emission control system to identify any visible signs of damage or malfunction. This may include checking the oxygen sensors, catalytic converter, EGR valve, EVAP system, and other related components.
Clear DTCs and test
After the repairs or component replacements have been performed, you can clear the DTCs from the vehicle’s onboard diagnostic system. The vehicle will then be tested to ensure that the emission system problem has been resolved. This may involve a road test or using specialized equipment to verify that the system is functioning correctly and that emissions are within acceptable limits.
