    Meaning of OBD Code

    OBD stands for Onboard Diagnostics. It allows you to check the health of your car and is available on most modern vehicles. If the check engine light shows on the dash screen, there is something wrong with your vehicle’s system, either in the engine, the body, or the chassis. Even a low tire pressure can trigger a check engine light. OBD2 codes are saved in the computer to direct you to which area of the system could be having a problem.

    The OBD code is a combination of letters, numbers, and symbols that can be used to communicate about what could be happening to your car’s systems. The first character is a letter that indicates the affected system in your car. For example: if you see an "E" in your code, there is a problem with the engine management system. The second symbol is a digit, which indicates whether the problem is generic or manufacturer-specific.

    OBD codes end with three digits which direct you to the exact issue in the system. To understand the precise meaning of the codes, you’ll have to rely on the internet, depending on your scanner type. If you are using a Bluetooth-enabled scanner connected to your phone, the Ancel app will explain the codes, and you can also contact the customer service agent through the app to explain the codes. If you have a budget scanner, you must Google the codes' meanings. A mid-range scanner will briefly explain what the scanned codes mean, while a more advanced one will give some deeper explanations.

    The first number represents what kind of fault has occurred; for example, if it says "P0304," this means that there is a problem with the fuel pump. The second number represents the fault diagnosed; for example, if it says "0161," this means that there is a problem with one of the sensors or wiring in your vehicle.

    If you have a newer vehicle, it will have an OBD2 port. This port is under the hood and connected to an ECU (electronic control unit). The ECU has electronic sensors that monitor everything from airflow to fuel consumption and emissions levels. When there are problems with one of these systems, the sensors relay information to the ECU, which you can only find out with a code reader.

     To read an OBD code, you need a scanner.What is OBD2 Scanner? A scanner is a device that can read codes from your vehicle's computer and display them on its screen.
