What does it mean when the check emission system light comes on?
The check engine light, also known as the malfunction indicator light (MIL), is a warning light that illuminates on the dashboard of a vehicle when the onboard computer detects an issue with the engine or emission control system. This light is designed to alert the driver that there may be a problem that requires attention.
Understanding the Check Engine Light
The check engine light is part of a vehicle's onboard diagnostics (OBD) system, which monitors various components and sensors related to the engine and emission control system. When the OBD system detects a problem, it sets a diagnostic trouble code (DTC) and turns on the check engine light to notify the driver.
The check engine light can indicate a wide range of issues, from minor problems like a loose gas cap to more serious issues like a malfunctioning catalytic converter or a problem with the engine's ignition system. The light may also come on if the engine is running too rich (too much fuel) or too lean (not enough fuel), which can affect fuel efficiency and emissions.
Diagnosing the Problem
When the check engine light illuminates, it's important to have the vehicle's diagnostic system checked as soon as possible. This can be done by taking the vehicle to a mechanic or using a diagnostic tool, such as an OBD-II scanner, to read the diagnostic trouble codes stored in the vehicle's computer.
- The diagnostic trouble codes can provide valuable information about the specific problem that triggered the check engine light.
- Once the problem has been identified, the mechanic can then diagnose the issue and recommend the appropriate repairs.
- It's important to note that the check engine light may come on for a variety of reasons, and not all of them are serious. In some cases, the light may come on due to a minor issue that can be easily fixed, such as a loose gas cap or a faulty sensor.
Ignoring the check engine light can lead to more serious and costly problems down the road, as the underlying issue may worsen over time. It's always best to have the vehicle inspected and the problem diagnosed as soon as possible to ensure the safety and proper functioning of the vehicle.
Can I still drive my car if it says emissions system problem?
It's not recommended to drive with the Check Emission System warning light on until you know the cause.
Is emission system serious?
Your vehicle's emission system greatly impacts its performance. It filters and reduces harmful gases, boosting engine efficiency. If it's malfunctioning, you'll notice decreased fuel efficiency, power, and acceleration, plus potential engine damage.
What is the most serious warning light in a car?
#1: Check Engine Light
The check engine light is something you shouldn't ignore because there are several possible reasons why this light could appear. Most common reasons include issues with the vehicle's emission system, engine components, or fuel compartment.
How much does it cost to fix an emission system?
If your vehicle failed emission testing and it needs repairing, then the cost will depend on the exact cause, but the repair work typically starts around $200. Replacing your exhaust system depends on the type of car you drive, but that work starts at approximately $175.
How much does it cost to fix emissions problems?
Minor fault repairs can set you back around £200, but if you've got a problem with your emission-reducing catalytic converter, expect a much higher bill.
Is it safe to drive with the emission warning light on?
It is ok for some time but if it starts to flash, then get it serviced as soon as possible. It can cause damage to the engine.
How do I fix my check emission system?
Diagnosing & Fixing the Problem

- Replace your air filter.
- Change faulty oxygen sensors.
- Take your vehicle to a mechanic.
What does it mean when my emission system warning light comes on?
This could be due to various issues such as a malfunctioning sensor, a problem with the catalytic converter, a leak in the exhaust system, or issues with the engine management system. It's essential to address this warning promptly as it can affect the vehicle's performance, fuel efficiency, and environmental impact.
