Bad Positive Crankcase Ventilation (PCV) System Lines
One of the most frequent problems with Honda Civics’ emissions systems is the Positive Crankcase Ventilation (PCV) system, also known as the PVC valve. Blower-by gases from your crankcase to your intake manifold are eliminated by PCV.
It has tubes that are prone to wear and tear. They might become harmed or blocked, turning on the Check Engine Light. Examine your PVC valve and fix or replace it if any problems are found to establish whether your PVC valve connections are defective.
Dirty Or Clogged Air Filter
The air filter in your car keeps dirt, trash, and other small particles out of the engine. Your Honda Civic’s Check Emission System light can come on if your air filter becomes soiled or blocked. There are two possible fixes for the emissions system problems in Honda Civic vehicles from 2012 to 2015. To fix the issue, you can either decide to clean your filters or replace them.
Evaporative Emissions Control (EVAP) System Damaged Components
The emission of dangerous gases into the environment from your fuel system is regulated by the EVAP system. Your emission control system may be impacted by the deterioration of its tubes, fittings, and cylinder. They must be promptly replaced if damaged.
Damaged, Missing, Or Loose Gas Cap
While your car is being parked, gas vapors could escape from a damaged, missing, or loose fuel cap, and gasoline could also evaporate. A loose gasoline cap may need to be taken off and put back on to fix the issue. If your gas cap is broken, changing it as soon as you can might fix the problem.
Broken Exhaust Gas Recirculation (EGR) System Components
The EGR system is in charge of allowing fumes to reenter the intake system whenever your combustion temperature rises. EGR pipelines may get clogged, EGR valves may malfunction, and EGR hoses may sustain damage. Examine your EGR for these flaws and replace any broken parts.
Damaged Air Cleaner Intake Hose
This hose immediately creates an emission problem as it ages and rips. This hose connects your air filter to the throttle body of your engine and feeds air into the combustion chamber. If the hose is damaged, debris and dirt could go inside and harm your engine. To solve the problem, get a new air cleaner intake hose and replace the old one.
How can the engine pollution alert be fixed?
Driving your car normally and waiting for the check engine light to go out on its own is the simplest way to reset it. Turn the car on and off three times straight if it still isn’t off after three days.
How can I address the issue with my Honda’s emissions system?
The good news is that there is a fairly simple solution to the emissions issue. Simply replacing the fuel injectors is all that is required. The bad news is that you might not be able to get the repairs for free because there hasn’t been a recall. You’re good to go if your Honda Pilot is still covered under warranty. If not, the expenses of the repairs will be your responsibility.
A service bulletin and a recall vary primarily in that the former is an elective repair that is covered by warranty or by the owner. The latter is essentially required and is taken care of by the manufacturer.
According to Repair Pal, the average Honda Pilot owner could expect to pay $500 for the repair. Although it’s not the most costly repair in the world, you’d still like to avoid spending $500 on auto repairs. Fortunately, the majority of Pilots from 2016 to 2018 are still protected by their original eight-year/80,000-mile warranties.
Check your VIN to see if your Pilot is still covered by warranty. If the repairs are already covered by your warranty, you might as well get them done now rather than waiting until the warranty is out and you’re stuck with the tab.
What does the check emission system light imply when it illuminates?
Every time you start the engine, along with other warning lights, the check engine light should illuminate briefly. This light is often a yellow or orange outline of an engine with the words “Check” or “Service Engine.” If it continues to run, something is wrong. If your check engine light flashes or blinks instead of remaining illuminated, there is a major issue that has to be fixed immediately. While many of the usual causes and solutions for an illuminated check engine light are straightforward, sometimes an engine light indicates a more significant issue.
I have an emission problem, can I drive?
Driving with the Check Emission System Warning Light On Is It Safe? Driving is not advised while the check emission system warning light is illuminated. This is because to the possibility that the issue causing the light to come on could harm your car. The issue should be resolved as quickly as feasible.
What is the cost of repairing an emission control system?
The cost of repair work for a car that failed emission testing will depend on the precise cause, but it usually starts at roughly $200. Depending on the kind of vehicle you drive, replacing your exhaust system can cost as little as $175.
Forever. Modern automobile exhausts are typically made of stainless steel or chrome to ensure long-lasting performance. The non-stainless steel exhaust systems on your car, on the other hand, only endure for about 5 years since the pipe can corrode, split, or develop holes.
Driving while your exhaust is blowing out is unsafe and should be avoided. You can breathe in fumes and flames from a blown exhaust while driving.
Reduced fuel efficiency, vibrations, and increased engine noise are a few indicators that you need a new exhaust system.
Just one component of the exhaust system is the muffler. It is used to lessen the noise that the engine’s exhaust makes. The entire system, from the cylinder head to the tailpipe, is the exhaust. The exhaust manifold, catalytic converter, muffler, and the pipes and fittings that join it to the chassis are only a few of the parts that make it up.
This is a misconception; no matter how effective they are, mufflers cannot increase your gas mileage. On the other hand, a limitation in the exhaust system can have a detrimental effect on your MPGs and the performance of your automobile because it can make it impossible for it to start.

What causes automotive emission issues?
Most gasoline-powered cars, including those with model years 1981 and later, as well as diesel cars older than five years must have emissions testing done every two years in Idaho. You can continue the registration process after passing emissions testing and receiving a Vehicle Inspection Report. Regrettably, you could not always succeed in passing emissions the first time.
If your vehicle appears to be operating smoothly, failing an emissions test will come as quite a shock. You are probably wondering just what the heck happened. These are six common reasons why a vehicle will fail emissions, and what can be done to fix it.
- You have a rich mixture of air and fuel. A rich air/fuel mixture is frequently the reason why an emissions test fails. This issue is typically brought on by a faulty oxygen sensor or injectors. Therefore, if you don’t pass the emissions test, get these parts checked out and perhaps replaced.
- Plugs have been worn out by you. Because of incomplete combustion, spark plugs that are defective or worn produce more emissions. Regularly check them, and replace them if necessary
- Your gas cap is damaged or leaking. This problem is simple to resolve. To begin with, make sure the cap is fastened securely. If not, make it tighter. In order to prevent unnecessarily failing an emissions test, this is frequently one of the first things they look for. However, if it is fastened tightly enough, it can still leak, which could lead to a failed emissions test. Simply replace the gas cap with one that will properly seal the tank if you do indeed have a leak in it.
- Your air filter needs cleaning. High quantities of hydrocarbons could be produced by a filthy or clogged air filter, which could result in a failed emissions test. The majority of manufacturers advise changing the filter once a year or every 12,000 miles. It might be a good idea to change your air filter before your emissions test if you can’t recall the last time you did so in order to pass.
Check emission system: What does that mean?
You can feel anxious if your check engine light turns on. Is a catastrophe about to occur? How much will it set you back? Don’t freak out; instead, consider why the light could be on and what you can do to fix it. To learn what might be wrong, keep reading below.
The check engine light turns on when the computer in your car thinks there’s a problem with the emissions control system that could or is already impacting your car.
The car’s computer stores one or more diagnostic fault codes when the light turns on. Even if the light is turned off, these codes will remain in place. You or your mechanic can use an OBD-II scanner to extract the codes and do troubleshooting to resolve a check engine light issue.
If your light is on, it usually implies that your car’s emissions control system is broken and it is polluting the air more than what is permitted by federal regulations. An emissions test or smog check would fail a car in this condition.
The maintenance or service light should not be confused with the check engine light. When a normal maintenance task is due, these lights turn on. They are typically set off by measurements of vehicle use, such as mileage, fuel consumption, or other factors.
What exactly does an emission system issue mean?
Your exhaust system and emissions control system can significantly impact your fuel efficiency. You can observe a considerable decrease in fuel efficiency if there is an exhaust leak or an emissions issue with parts like the fuel tank, carburetor, catalytic converter, muffler, or exhaust manifolds.
How long should the emissions light be on when driving?
It is still possible to drive your car if your check engine light comes on for any reason, but it is only advised to drive another 50 to 100 miles before checking your car’s computer for error codes. You can pinpoint the problem at hand using this technique and deal with it however you see proper.
Depending on the problem that caused the Check Engine light to come on, you could be able to keep driving for a very long time or only a few days. The engine computer has time to reset some sensors after traveling between 50 and 100 miles, which could resolve the issue.
