You may have seen the check emission system warning light if you own an Acura. This can be confusing, especially if you don’t know what it means. You may wonder what you need to do to get the light to turn off. Here’s what you need to know about the check emission system warning light on your Acura.
The check emission system warning indicates that there is a problem with the vehicle’s fuel cap. It could also indicate a faulty emissions control system, especially the EVAP (Fuel Evaporative System).
In this blog post, I will discuss what the check emission system warning means on an Acura and how to fix it.
What Does Check Emission System Mean on an Acura
These are some of the things that can lead to a check emission system warning in your Acura:
Loose or Missing Gas Cap
The most frequent reason the check emission system warning is because the gas cap is loose or missing. When you have a loose gas cap, it needs to be tightened. If the gas cap is missing, you’ll need to replace it.
Causes of a Loose Gas Cap
The gas cap may be loose because:
- It wasn’t tightened properly after the last fill-up
- It’s damaged or worn out
- The threads on the gas cap are stripped
Consequences of Not Tightening a Loose Gas Cap
If the gas cap isn’t tightened properly, it can make fuel vaporize and escape from the tank. This is not only wasteful, but it can also lead to a check emission system warning light. This problem can also lead to stalling or rough idling while driving.
How to Fix a Loose Gas Cap
Tightening the gas cap should be your first course of action if the check emission system warning light comes on. Here’s how to fix a loose gap:
- Pull over and park your car in a safe location.
- Turn off the engine.
- Locate the gas cap. It’s usually on the right side of the vehicle, near the back.
- Unscrew the gas cap by turning it to the left (counter-clockwise).
- Tighten the gas cap by turning it to the right (clockwise) until you hear it click.
- Replace the gas cap if it’s damaged or worn out.
Missing Gas Cap
If your gas cap is missing, you’ll need to replace it. You can purchase a replacement gas cap from your local auto parts store or the dealership. Be sure to get one specifically for your vehicle’s make and model.
Faulty Emissions Control System
Another potential cause of the check emission system warning light is a faulty emissions control system. This is most likely the EVAP (Fuel Evaporative System).
The EVAP system captures fuel vapors that come from the fuel tank. It then stores them in a canister. When the engine is running, the vapors are drawn into the engine and burned.
If there’s a faulty EVAP system, it can cause the check emission system warning.
Causes of a Faulty Emission Control System
The most common EVAP problems include:
- A leak in one of the hoses or valves
- A faulty purge valve
- A faulty canister
- A faulty fuel tank pressure sensor
How do I Fix a Faulty Emissions Control System?
If you have a problem with the EVAP system, you’ll need to take it to a professional for repair. They will be able to diagnose the problem and fix it. In some cases, you will have to replace parts of the system.
Is It Recommended to Keep Driving while The Check Emission System Light On?
It is generally safe to drive while the check emission system light on. However, you should take action to fix the problem with immediate effect. Driving with the Check Emission System on can lead to:
Decreased Fuel Economy
Your Acura will run less effectively if the gas cap is loose or missing. This will lead to decreased fuel economy.
Damage the Engine
If the problem is with the EVAP system, it can cause damage to the engine after a while. This is because unburned fuel vapors will be drawn into the engine.
So, if you see the check emission system light come on in your Acura, take action right away to solve the problem. By taking care of it quickly, you can avoid more serious issues down the road.
The check emission system light on your Acura is usually due to a loose or missing gas cap. In most cases, this is an easy fix that you can do yourself. However, if the problem is with the EVAP system, it will require a trip to the mechanic. I hope this article has helped you understand what the check emission system light means and how to fix it.
