What Does the Orange Engine Light Mean? Understanding Check Engine Indicators

It can be helpful to think of your vehicle's warning lights as an attempt to tell you when something might be wrong and requires your attention. Whether you're a new car owner or you simply haven't experienced an illuminated warning light before, it's always helpful to have an understanding of what each light means as this will ensure the correct steps are taken to prevent further issues.

If you want to know what the light telling you to check engine means, you're in the right place.

What is a Check Engine Light?

Sometimes referred to as 'CEL' in vehicle manuals, the orange car engine light is a small symbol on the dashboard shaped like an engine. This light will glow in an orange colour when something related to your engine requires attention.

Are There Different Types of Engine Light?

Your engine light can communicate whether your vehicle's engine is experiencing a minor or a more serious issue. Here's what to look out for…

A Solid Yellow/Orange Glow

If your vehicle's computer system senses that there is a minor problem with your engine, the check engine light will glow yellow/orange. If this occurs as you are driving, there is no need to panic or pull over straight away.

Provided that your vehicle is performing normally and you aren't hearing any unfamiliar sounds, you're safe to continue with your journey. Just make sure to schedule an appointment with a car specialist by searching for your nearest Protyre garage to have the issue checked out when you reach your destination.

A Blinking Orange or Solid Red Glow

A more serious issue with the engine may be indicated with either a blinking orange or solid red car engine indicator light. If this occurs when you are driving, it is important to pull over as soon as it is safe. Once you have safely pulled over, you should arrange to have your vehicle picked up by a recovery truck. This type of warning light is indicative of a serious problem with your engine and it would not be safe to continue driving.

Common Reasons For Your Engine Light To Turn On

There are a variety of reasons why your car engine indicator light might turn on. Here are some of the most common…

Fuel System

There are numerous valves lining your fuel tank, which are there to stop fuel vapours from escaping. Sometimes leaks can occur here, which will prompt your vehicle's engine light to turn on.

Broken Oxygen Sensor

Your vehicle's oxygen sensor is consistently measuring oxygen levels in the exhaust system. This information is processed by your car's onboard computer to regulate the amount of fuel and air that is channelled into the cylinders. If this sensor isn't working properly, your engine will likely be burning significantly more fuel than usual. While your engine will still function, it can cause damage to your catalytic converters or spark plugs.

Faulty Catalytic Converter

When your catalytic converter isn't functioning properly, your fuel economy will reduce and your emissions will increase.

Dead Battery

Battery issues are one of the most common causes of an engine warning light coming on. If your battery has been disconnected recently, you may simply need to reset the electrics in your vehicle.

Ignition Problems

If your ignition coil isn't functioning properly, the air and fuel mixture in your cylinders won't ignite, and you will likely run into problems very quickly. Similarly, if your spark plugs are corroded or contaminated, your engine may misfire, fail to perform optimally when accelerating, or cut out completely.
