What if you’ve started your car and you saw the warning lights are lighting up as they usually do after a bulb check? However, later all of them cleared out except one. This one is called a malfunction indicator lamp or popularly known as Check Engine Light. You noticed this light is on and not going out at all.
You see, the MIL lights up to indicate that a sensor in your engine and drivetrain control system has transmitted a reading to the engine’s computer. Which is unrelated to regular parameters, and it’s been recorded as an error code by the computer. The Society of Automotive Engineers established criteria for its OBD II codes for cars in the mid-1990s.
These trouble codes are unique to each car, while others are common to all manufacturers in Asia, the USA, and Europe. The error codes are divided into four primary groups:
- The letter P stands for powertrain, which includes engine, emissions, and transmission.
- The letter B stands for the body that encompasses the temperature control, airbags, lighting, etc.
- The letter C stands for chassis. This includes the parts of your car, for example, electronic brake, steering, auto power control, and anti-lock brakes.
- The letter U stands for network communications such as controller area network wire and modules, cars after 2006.
An engine code with a 0 as the second number is universal, meaning it refers to every car and manufacturer. A trouble code with a 1 as the second number is an “enhanced” code. This is for a certain manufacturer and might need additional diagnostic data about the car.
Each letter and number combination in a vehicle entails a certain kind of issue, no matter if it’s a general case or something particular from the manufacturer.
- P0171–P0175: These codes are used to calculate oxygen levels to understand how much oxygen you’re getting.
- For diagnostic services, P0300-P0305 codes are used. Here Check engine misfires and evaporative systems are the references of these codes.
- Codes P0411, P0440, P0442, P0446, and P0455 are all related to exhaust gas recirculation systems.
Note: You see, the MIL isn’t a basic symptom. Therefore issues such as low oil compression or overheating won’t flash the MIL. However, they can make other lights or meter readings glow. Also, you can find the error codes like 7ea in vehicle identification number and engine codes.

Whether it’s an OBD-II or OBD2, your scanner will return a $7E8 and $7EA, and perhaps display $7E9 code as well. Well, they’re the options for a sub-menu. If there’s a supported module in your scanner, you should receive a usual “P0” code when you tap on one at a time.
