An issue with the ratio of fuel to air in the engine is indicated by the emission system warning light. Between 40,000 and 60,000 miles, the fuel injectors in the Honda Pilot can malfunction. Also possible for replacement is an oxygen sensor located close to the catalytic converter.

What Does It Mean When the Emission System Light Comes On?
You can notice a misfire, a rough idle, and poor fuel economy if the emission system light is on. There are numerous factors that can turn on the emission system light. Fuel injectors that are malfunctioning, defective MAF or oxygen sensors, or a loose gas cap could all be to blame.
Step 1: Check the Air Filter on the Air Cleaner System.
This system draws air from the outside of the vehicle and filters it before it enters the engine. Any number of issues, including an issue with the emissions system, might be brought on by an obstructed or unclean air filter.
Step 2: Inspect the Positive Crankcase Ventilation.
Unburned gases from the engine are returned to the combustion chamber via the Positive Crankcase Ventilation, or PVC. These gases will escape through the dipstick tube if this isn’t happening.
Start the engine without the oil fill cover in place to see if this is the case. If you notice smoke coming from behind the hood, your PVC probably isn’t operating properly.
Step 3: Consider Using Evaporative Emissions Control System.
It functions by recirculating gasoline tank fumes through a carbon canister. This arrangement, in which the exhaust is released into the atmosphere, is typical of automobiles with closed fuel systems. If this system is in your car and it isn’t functioning, you’ll probably see a check engine light.
Step 4: Check the Exhaust Gas Recirculation System.
Exhaust gases are recirculated back into the engine via the Exhaust gas Recirculation (EGR) system so they can be burned once more. The Pilot may generate too much pollution if the EGR system isn’t working properly.
Start the engine, then let it idle for a while to inspect the EGR system. Then, activate the air conditioning and place your hand over the tailpipe. If you detect a significant suction coming from the tailpipe, the EGR system needs to be repaired because there is a problem.
Step 5: Check the Air Injection System.
To aid complete the combustion process and lower emissions, it operates by infusing a little amount of air into the exhaust stream. If it isn’t functioning correctly, the OBD-II system may display a P0420 error code.
Steps:
- Verify that the pump is receiving power.
- Examine the air injection tubes for obstructions.
- Examine the hoses and fittings for leakage.
- the air injection pump location
- Examine the solenoid and check valves.
Can you drive with a malfunctioning emissions system?
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 does “emissions system malfunction” refer to?
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.
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.
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.
How long can you maintain an exhaust light while 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.
How is an emission system cleared?
Does it appear that the first strategy is failing? You might now want to try an alternative method for resetting the service emission system.
Some dashboard lights can be fixed by driving for 1030 minutes; however, if the service emission light is still on after that, find a secure parking space.
After that, start the car, turn it off, and then start it again three times in a row. If a malfunction causes the dashboard light to come on, doing this should turn it off.
Even though it’s really basic, this fixes minor electrical issues. It only shuts off electricity and restarts broken electrical parts, including the dashboard lights. Please give this method a shot before moving on to something more difficult.
Is the check engine light also an emission light?
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.
