The Honda Civic has won the hearts of millions of people worldwide because it is known for being a safe and fuel-efficient small car. The Civic has become a standard in its field because of its incredible speed, low pollution, beautiful style, and high fuel economy.
Even though this happens to many cars, the check engine light on your Honda Civic may be on. This means there will be a problem with the smog control that needs fixing soon. On some Honda Civics, such as 2012, 2016, 2017, 2018, 2019, 2020, and 2022, the display might show Emission System Problem.
Even the most reliable and highly rated cars can have problems. In other words, the Honda Civic might have issues with technology just like any other car.
Many people who own this car are worried about the emissions system.
What Does The Check Emission System Mean?
The Honda Civic’s emission system consists of several parts that work together to reduce the dangerous pollution released into the air. Parts of this system are:
- The oxygen sensors.
- The internal monitoring system.
- The exhaust gas return valve.
- The catalytic converter.
- The oxygen sensors.
The catalytic converter reduces harmful gasses from the engine by using palladium and platinum as catalysts to speed up chemical processes inside the engine.
The exhaust device releases these less dangerous gases out into the air. If parts break or don’t work right, the pollution system could have big problems.
A sign that says Emission System Problem shows up on the panel of a Honda Civic when the system’s sensors detect a problem. Several things could be causing this issue. Some of these parts have nothing to do with the catalytic converter or the exhaust system.
Common Causes of Emission System Issues
1. Failure of a Catalytic Converter
Sometimes, problems like carbon deposits or dirty fuel can block the catalytic converter, which decreases its efficiency and power while increasing emissions. Signs that this might be happening include experiencing reduced acceleration and noticing the Check Engine light turning on. Several factors can contribute to these issues, such as a faulty oxygen sensor, a malfunctioning mass air flow sensor, worn-out spark plugs, or damaged spark plug wires.
2. Oxygen Sensor Failure
When oxygen sensors malfunction, they can mess up fuel mixture, causing issues with the engine. These sensors are typically located on the exhaust manifold. Signs of this problem include receiving an emissions fault code and experiencing compromised performance from the emission system.
3. Problems with the Exhaust Gas Recirculation Valve (EGR)
When the EGR valve gets jammed, it affects the engine’s performance and emissions. Regular oil changes help prevent carbon buildup and blockage in the valve. Cleaning the EGR valve can solve the issues without needing specialized repair skills.
4. Dirty Fuel Injectors
Clogged fuel injectors can mess up the proper mix of fuel and air in the engine, causing more emissions. Signs of this issue include misfiring, vibrations while idling, and fluctuations in the RPM gauge. When you notice these engine problems, it’s likely that the fuel injectors are causing them. Identifying and fixing clogged fuel injectors promptly can help keep the engine running smoothly and reduce emissions.
5. Errors in the Onboard Diagnostic System (OBD)
A broken OBD system may fail to detect emission system problems, making diagnosis harder.
6. Bad or Loose Gas Cap
Issues with the gas cap can cause emission problems, leading to issues like bad fuel economy and a rough engine idle. To stop this, make sure the gas cap is in good condition and tightly closed. If you encounter problems, consider replacing it with an original Honda part for the right fit and better quality.
Understanding these causes helps maintain a well-functioning emission system in your Honda Civic, promoting optimal engine performance and reducing environmental impact.
How Do You Fix The Emissions System Problem?
If your car’s EVAP (Evaporative Emission Control) system leaks, it means there’s an issue with the part designed to gather and store fuel vapors from the tank to prevent them from escaping into the air.
1. Handling Simple Repairs
- Depending on your Honda Civic’s year model, you can manage simple issues like a dirty air filter or a damaged air cleaner intake.
- Simple fixes, such as cleaning the air filter, can usually be done by yourself.
2. Cleaning the Air Filter
Using a Vacuum
- Connect a vacuum hose and vacuum both sides of the air filter.
- Ensure thorough cleaning under a bright light to remove all the dirt.
- If there is extra dirt, vacuum it for a maximum of 4 minutes before shifting it.
Cleaning with water
- Mix some detergent in a bucket of water and make sure everything gets cleaned properly.
- Wash the air filter with water to get very clean air.
- When cleaning, spread the filter out on a clean cloth to dry completely before replacing it.
3. Fixing a Damaged Air Cleaner Intake Hose
- Replace the air cleaner intake line if it breaks and causes the problem.
- Seek assistance from a professional or purchase a replacement hose from a local auto parts store to fix it yourself.
4. Expert Diagnosis for Complex Issues
- If you’re experiencing more complex problems with the Check Engine light, contact a mechanic for help.
- An expert technician will utilize diagnostic tools to understand codes, identify particular issues with the exhaust system, and provide accurate solutions.
- Staying away from do-it-yourself (DIY) solutions for complex issues ensures the modifications are made correctly and keeps you safe.
5. Efficient Diagnosis Saves Resources
- When issues come up, it’s best to call in the professionals instead of attempting a DIY solution.
- If the problem is minor and manageable by experts, you might be able to avoid spending more money on components.
- If engine issues are identified and addressed promptly, they may not worsen.
- Whether fixing your Honda Civic’s air system is simple or hard is dependent on your method. It will be better for the environment and it will operate better.
Is It Safe To Drive With An Emission System Problem?
If your car’s emissions light system isn’t working right, you should always avoid driving that car with this fault. The pollution system of a car is very important for controlling and lowering the amount of pollution that is released. If you keep driving with an exhaust system that doesn’t work, a lot of problems could happen.
Conclusion
In short, it’s very important to fix a problem with the Honda Civic’s 2012, 2016, 2017, 2018, 2019, 2020, and 2022 emissions systems. If you don’t, your car might not work right, and you might even get in trouble with the state.
The emission system reduces harmful elements from the car’s pollution, helping to keep the air clean. It’s not just about the car; we need to take care of the environment too. If you see anything wrong with your car or the panel lights, tell an adult to check it out. Getting things fixed quickly will help keep the air we breathe safe and clean and your car running well.
