The sensors in your powertrain are responsible for the monitoring of the operations of various components and are linked to a system known as On-Board Diagnostic II (OBD-II). The check engine light quickly calls your attention to any malfunction in your vehicle. Depending on the vehicle or brand, the light is usually red, yellow or orange. Some carmakers are making it easier by writing the words “Check engine Light” alongside the colour on the dash. 

When people say cars talk, don’t stand in disbelief. There are several ways cars communicate with their owners if only they paid attention. One of the ways is through the check engine light. It doesn’t necessarily mean you are in trouble. It could be minor issues like loose gas caps. The light gives information and provides diagnostics to car problems.

How do I solve the check engine light issues?

Solving the check engine light issues is easier than you thought. We understand it could be a nightmare for drivers especially when it happens in the middle of nowhere. The first thing you need to do is take a look at the code which can be viewed on the vehicle’s computer system. It can also be read by the OBD II via the OBD connector port (found under the steering column). If you find it difficult reading the code, take your car to a repair facility for an expert to do that for you. If you want to avoid the stress of taking it to a workshop, you can buy a scanner to read the code yourself. Luckily, the scanner is cheap. It goes as little as $15. When you get the code, insert it into any search engine along with the vehicle’s description. By doing that, you will find the description of the issue on the net or closely related ones. 

However, we often recommend our readers to avoid guess work. It won’t cost you too much if you take your car for diagnosis at a workshop. One of the reasons for such is that DIY code reading might not give you the accurate problem.
