We’ve all been there – driving along and minding our own business when all of a sudden, a light pops up in the dashboard. The light looks like the outline of a car’s engine, and in some cases has the words “check” or “check engine” as a further indicator. This is the check engine light, which is one of the most dreaded signs among drivers nowadays.

If your check engine light is on, there is some good and bad news. The good news is that it doesn’t mean something is horribly wrong with your car. The bad news, however, is that it can also mean that something is very wrong with your car. In today’s blog, we are showing you five potential scenarios behind an illuminating “check engine” light.

Engine issues

The first thing that commonly triggers a check engine light is engine problems. This light appears based on the signals received through a collection of sensors, and when a problem is detected, the light is on. The engine problems can also mean air or fuel delivery issues, which is why the car engine doesn’t perform as it should.

Transmission issues

Next on the list are problems with the transmission. As you know, the car’s transmission is a system that manipulates the engine power, transferring it to the drive wheels. These two assemblies work together closely, which is why a problem with the transmission can produce tailpipe emissions – illuminating as a check engine light on your car’s dashboard.

Emissions equipment issues

Most modern cars come with advanced systems that relate to the emissions equipment. These include the exhaust gas recirculation system, the evaporative system, the catalytic converter, and so on. Each of these systems is unique and designed to minimize tailpipe emissions and in that way protect the environment. A “check engine” light can mean there is a problem with some of these emission systems – we won’t list all of them since there are too many.

Issues with electronics, modules, and sensors

Modern cars have plenty of electronics, and all of these may sometimes cause problems with the powertrain controls. This is basically the signal the engine receives and returns from the car. This type of computerized signal is part of a vast data network full of sensors, modules, and wires which can typically trigger the check engine light.

Ignition system issues

The ignition system is a collection of spark plugs, coil packs, and a lot of other things that ignite the air/fuel mixture inside the engine. The control module is what monitors the operation of this system, and is often an indicator that can signal the check engine light if it detects a problem.

Driving with the check engine light on is generally ok if you don’t notice anything unusual. However, it is only recommended for a short distance – whether you are visiting your local mechanic or driving to your garage. So, if you see the check engine light on your dashboard, proceed with caution and be sure to get it diagnosed and repaired. After all, that is the only right way to prevent further damage.
