5 different facts that you must know regarding OBD Code readers are discussed below in order to give you a detailed overview regarding the operations and utility of this handy device.

1. A few details on the working mechanism of OBD Code Readers

Majority of the car enthusiasts are already familiar with the fact that cars contain a number of sensors that help in keeping the owner informed about their functionality.

Some of the most common sensors include check engine lights, oxygen sensors, manifold pressure sensors, hydraulic sensors, engine knock sensors, etc.

All these sensors are developed in a way that they continuously keep on producing signals and transmitting them to the car’s computer or its ECU (Engine Control Unit).

These signals when received by the computer are then used to maintain and optimize the performance of all the components of the car.

If the signals generated by one of the sensors are unusual in any way, the computer detects it and generates a DLC code immediately. This is done in order to intimate the car’s owner about the fact that something is not right.

As a consequence of this entire process, the check engine light situated by the odo meter of the car gets lit up. The check engine light has two different operational modes.

If it stays on constantly, it suggests that the car is experiencing a mild issue that does not require immediate attention. You can check it out at your convenience if you can’t find the opportunity to do it right away.

On the other hand, if your check engine light is blinking, your car needs to be taken care of right away. It is not safe to continue driving your car in such a scenario.

The check engine light does not offer any specific information on what actually is going wrong with the car. All it tells you is something is not right without pin pointing to the exact issue. This is where the OBD car reader comes in.

When you plug it into your car; it acquires the exact information from the car’s ECU and informs you about the actual ongoing fault in the car.

The most basic models of OBD code readers usually offer a DLC code only. But if you own a good, professional model, it also offers some useful details on the problem and how to diffuse it.
