Engine Management Light Check

The engine management light can alert you to an issue with your vehicle and having this appear can be of some concern, but how serious is it and what actions do you need to take.

Commonly known as the "check engine light," the engine management light (EML) is a dashboard indicator that turns on when there is a problem with your vehcles engine, exhaust, or emissions system. The EML is a general warning that something is wrong with your vehicle rather than a specific issue like a "low coolant" or "check oil level" message or light would be.

Modern vehicles are fitted with on-board sensors which can monitor how the engine and other components are performing including:

Spark Plugs or Ignition Coils

When one of your spark plugs or ignition coils is malfunctioning, the check engine light will also often turn on. It's possible that something isn't firing properly, which could result in decreased engine performance, and the check engine light is alerting you to the issue.

Oxygen Sensors

Oxygen sensors are part of your emissions system and are used to identify problems with the exhaust. The check engine light would most likely come on if there are pollution issues. The sensor itself may occasionally malfunction or produce inaccurate results, necessitating replacement.

Loose Fuel Cap

This one is actually quite common. Sometimes you don't tighten the fuel cap all the way (listen for the click), or perhaps you never replaced it in the first place. In any case, it's a simple issue to identify and resolve.
