Diagnostic trouble engine codes (or fault codes) are codes that are stored by the on-board computer diagnostic system.

These codes are stored when a sensor in the car reports a reading that is outside the normal.

The trouble engine codes, or diagnostic code, are an alphanumeric value that corresponds to a particular problem. Every car built since 1996 has an (OBD) computer system that monitors and identifies issues.

In particular, it looks for issues that may result in harmful and polluting emissions from exhaust gases. When this system identifies an issue it turns on the check engine light and records an (OBD) code.

OBD-II – OBD Stands For On-Board Diagnostics Codes

There are literally hundreds of different codes a Check Engine Light can represent. While that sounds daunting, with a little patience, tackling basic diagnostics will give you useful knowledge about your vehicle.

On-Board-Diagnostic (OBD) trouble codes are one way your vehicle communicates with a mechanic. Every car built since 1996 has an OBD computer system that monitors and identifies issues. In particular, it looks for issues that may result in harmful and polluting emissions from exhaust gases. When this system identifies an issue it turns on the check engine light and records an OBD code.
These codes provide a mechanic with information about the system and the conditions under which the issue was first identified. However, they can’t provide a clear-cut solution to the actual cause of the problem – only clues for where to look.
