When the engine management light (EML) is on, it is essential not to ignore it. This amber EML symbol is a crucial dashboard light that signals a potential problem in your car, which could lead to a breakdown or even an MOT failure. A sensor within the engine or emissions system may trigger the EML.
This guide provides all the information you need to identify common causes and solutions for the engine management light (EML).
What does the amber engine management light (EML) mean?
The engine management light (EML) should illuminate when you start the vehicle and switch off after a few seconds. However, if the EML stays on or starts flashing, it may indicate an issue with the engine or one of its related systems.
Your car’s dashboard contains various lights and notifications, but the engine management light (EML) is essential. Any driver who sees the EML light should promptly take their vehicle to a trusted local garage or call a mobile mechanic to do the necessary repairs.
Can I drive with the engine management light on?
If your engine management light (EML) comes on, it’s best to have a mechanic check and fix the problem immediately. Driving with the EML light on can cause more damage to the engine and other systems and reduce performance.
While it might be a minor issue that needs a quick repair, addressing it promptly can prevent further damage to your vehicle and save you money in the long term.
What causes the engine management light to come on?
Modern vehicles are complex, with numerous electrical components that impact the engine and drivetrain. Sometimes, these components can experience issues or faults. Here are some common problems to be aware of:
Reason 1 – Catalytic Converter
This crucial engine component controls vehicle emissions. If it malfunctions or has a connection issue, the engine management light will appear on your dashboard.
Reason 2 – Ignition System
This can involve issues with spark plugs, ignition coils, or other parts of the vehicle’s starter motor. Several electrical systems feed into this component, and if they have problems, the light will appear.
Reason 3 – Clutch
If your clutch is slipping or the gear system sensors are failing, you will see the engine management light. In this case, it is important to take your car to a garage immediately.
Reason 4 – Engine Misfire
Certain engine parts can overheat, leading to a misfire, which can result in sudden juddering while driving and cause the dashboard light to appear.
Reason 5 – Faulty Sensors
While the above four points involve sensors, many more sensors are installed throughout any vehicle. If these are linked to major engine or electrical system components, they will trigger the appearance of the engine management light.
How to reset the engine management light
If the engine management light (EML) is on, it should reset itself after fixing the issue. Most modern vehicles have an onboard computer that monitors the engine and electrical systems and alerts the driver to any issues that need attention. If there are no problems, the light should turn off on its own. However, in some cases, the EML may stay on due to the original fault persisting or a new one emerging.
If the light remains on, it is best to take your car to a garage and have a mechanic check it. Sometimes, the light may stay on because of an electrical fault. In such cases, you can try removing the battery, reattaching it, and starting the engine. If the light is still on, a mechanic may need to use an “On Board Diagnostic Scanner” to pinpoint the problem and provide the best options for resolving it.
