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) codes are accessed by; plugging a code reader into the vehicle’s (OBD) port. 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.

So, Is your Check Engine light on? Are you wondering what it means? Your car knows, and it stores comprehensive information; on what’s wrong in the form of Trouble Codes.
